Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Bitcoins are mined using a cryptographic algorithm called SHA-256. This algorithm is simple enough to be done with pencil and paper, as I show in this video. Not surprisingly, this is a thoroughly impractical way to mine. One round of the algorithm takes 16 minutes, 45 seconds which works out to a hash rate of 0.67 hashes per day.

https://www.udemy.com/blockchain-for-business-the-new-industrial-revolution/?couponCode=YOUTUBE Bitcoin and cryptocurrency mining explained with the the Byzantine Generals Problem. The Byzantine Generals problem was first introduced in a computer science paper published in 1982. The problem discussed in the paper is that reliable computer systems must be able to function effectively in the presence of faulty components that may send conflicting information to different parts of the system. This issue is even more acute when we talk about decentralized computer networks. Imagine the following thought experiment: The Byzantine army has surrounded an enemy city. The army is organized into several units. Each unit is commanded by a general and they all need to come up with a coordinated plan of action. However, they are located away from each other and the only means to communicate among themselves is via messages. To make things more complicated, one or more of the generals are possibly traitors. The presence of disloyal generals means that misleading messages could be sent aiming to disrupt any coordinated plan of action, be it attack or retreat. To find a successful solution to this conundrum, the Byzantine army needs to find its path to coordinated action, one way or another. To achieve this, the Byzantine army needs an algorithm that works effectively towards a coordinated outcome where the loyal generals follow it and the traitors don’t. Now that you are familiar with the problem, let’s see its solution. It is called the Byzantine Fault Tolerance algorithm. Over the years, there have been several proposed theoretical solutions involving game theory and math. The first practical implementation of Byzantine Fault Tolerance algorithm came with the Bitcoin’s Proof-of-Work. In this case the “generals” are nodes on the Bitcoin network, also known as “miners”. A network node is a connection point that can receive, create, store and send data across a network. In other words, nodes are the connected dots that make up a network. To simplify, think of it in the following way. In the image we traditionally use to depict a blockchain, every single computer is a separate node. They are all connected and can receive, create, store, and send data to each other. In the context of the Byzantine Fault Tolerance algorithm, the important concept to grasp is that these mining nodes start from the assumption that nobody else on the network can be trusted. Proof-of-Work secures network consensus even in the presence of non-compliant nodes. That is, even if there are some Byzantine generals who are not acting in the army’s best interest, coordinated action can still be achieved. Let’s see how this mechanism works in Bitcoin. As we all know by now, Bitcoin is a peer-to-peer network where all activities are done by its users through appropriate software and hardware. These activities include making transactions, receiving transactions, and verifying and transmitting transactions. Now, this is where we need to introduce the concept of “mining”, which many of you have probably heard. Mining is an activity, carried out by network participants, which involves Proof-of-Work and results in generating new coins as a reward for the miner who successfully did this Proof-of-Work first for each new block.

This is part 4 of the Blockchain tutorial explaining what cryptograhy is and also what encrypt and decrypt means. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Home page: https://www.3blue1brown.com/ Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives the desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

We first propose a scalable framework where user can use his attribute values and a search query to locally derive a search capability, and a file can be retrieved only when its keywords match the query and the user’s attribute values can pass the policy check. Using this framework, we propose a novel scheme called KSAC, which enables Keyword Search with Access Control over encrypted data. KSAC utilizes a recent cryptographic primitive called HPE to enforce fine-grained access control and perform multi-field query search. Meanwhile, it also supports the search capability deviation, and achieves efficient access policy update as well as keyword update without compromising data privacy. To enhance the privacy, KSAC also plants noises in the query to hide users’ access privileges. Intensive evaluations on real-world dataset are conducted to validate the applicability of the proposed scheme and demonstrate its protection for user’s access privilege.

However it seems that this is NOT correct. Please read: https://blog.iota.org/official-iota-foundation-response-to-the-digital-currency-initiative-at-the-mit-media-lab-part-1-72434583a2 This is part 1 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. IOTA is not an acronym for Internet of Things, (IoT) but it just mean something very small. David Sønstebø, Sergey Ivancheglo, Dominik Schiener and Serguei Popov founded IOTA in 2015. IOTA Foundation main focus is Internet of Things and the Machine Economy but this technology is well suited for payments between humans as well. The IOTA white paper can be found at: https://iota.org/IOTA_Whitepaper.pdf All IOTA's which will ever exist have already been created. The total IOTA supply is: 2,779,530,283,277,761 IOTAs IOTA features - Scalability The network becomes stronger when the number of transactions increases. IOTA can achieve high transaction throughput. - Decentralisation IOTA has no miners. Every transaction maker is also a transaction validator which means every transaction maker actively participates in the consensus. - No transaction fees IOTA has no transaction fees which means IOTA can be used for micropayments. - Quantum computing protection Quantum computers will be able to crack current data encryption methods much faster than current classical computers. IOTA uses the Winternitz One-Time Signature Scheme which is a quantum-resistant algorithm. See: https://eprint.iacr.org/2011/191.pdf IOTA is the 3rd generation public permissionless distributed ledger, based on a Directed Acyclic Graph (DAG). IOTA called this DAG the tangle. The tangle is NOT the same as the Blockchain. A tangle is a data structure based on Directed Acyclic Graph (DAG). Each transaction always validates 2 previous non validated transactions. Directed means the graph is pointing to one direction. Tips are the unconfirmed transactions in the tangle graph. Height is the length of the longest oriented path to the genesis. Depth is the length of the longest reverse-oriented path to some tip. Making a transaction is a 3 step process: - Signing: Your node (computer / mobile) creates a transaction and sign it with your private key. - Tip Selection: Your node chooses two other unconfirmed transactions (tips) using the Random Walk Monte Carlo (RWMC) algorithm. - Proof of Work: Your node checks if the two transactions are not conflicting. Next, the node must do some Proof of Work (PoW) by solving a cryptographic puzzle (hashcash). Hashcash works by repeatedly hashing the same data with a tiny variation until a hash is found with a certain number of leading zero bits. This PoW is to prevent spam and Sybil attacks. The goal of the Random Walk Monte Carlo algorithm is to generate fair samples from some difficult distribution. The Random Walk Monte Carlo (RWMC) algorithm is used in two ways: - To choose two other unconfirmed transactions (tips) when creating a transaction. - And to determine if a transaction is confirmed. To determine the confirmation level of your transaction we need the depth to start from and we execute the Random Walk Monte Carlo algorithm N times, the probability of your transaction being accepted is therefore M of N. M being the number of times you land on a tip that has a path to your transaction. If you execute RWMC 100 times, and 60 tips has a path to your transaction, than your transaction is 60% confirmed. It is up the the merchant to decide to accept the transaction and exchange goods. It is the same as Bitcoins where you want to wait for at least 6 blocks for high value transactions. Transactions with bigger depths takes longer to be validated. An IOTA Reference Implementation (IRI), wallet and libraries are available at: https://github.com/iotaledger To setup a full node you need to tether with neighbours by exchanging your ip address with theirs. Once you have sent a transaction from an address, you should never use this address again. A tangle can get branch off and back into the network. This is called partitioning. The Coordinator or ‘Coo’ for short, are several full nodes scattered across the world run by the IOTA Foundation. It creates zero value transactions called milestones which full nodes reference to.

Mobile: (0) 9952649690, Email: [email protected], web: http://www.jpinfotech.org Privacy has become a considerable issue when the applications of big data are dramatically growing in cloud computing. The benefits of the implementation for these emerging technologies have improved or changed service models and improve application performances in various perspectives. However, the remarkably growing volume of data sizes has also resulted in many challenges in practice. The execution time of the data encryption is one of the serious issues during the data processing and transmissions. Many current applications abandon data encryptions in order to reach an adoptive performance level companioning with privacy concerns. In this paper, we concentrate on privacy and propose a novel data encryption approach, which is called Dynamic Data Encryption Strategy (D2ES). Our proposed approach aims to selectively encrypt data and use privacy classification methods under timing constraints. This approach is designed to maximize the privacy protection scope by using a selective encryption strategy within the required execution time requirements. The performance of D2ES has been evaluated in our experiments, which provides the proof of the privacy enhancement.

What is Hashing & Digital Signature in The Blockchain? https://blockgeeks.com/ Today, we're going to be talking about the word blockchain and breaking it down to understand what does it mean when someone says, "Blockchain." What is hashing? Hashing refers to the concept of taking an arbitrary amount of input data, applying some algorithm to it, and generating a fixed-size output data called the hash. The input can be any number of bits that could represent a single character, an MP3 file, an entire novel, a spreadsheet of your banking history, or even the entire Internet. The point is that the input can be infinitely big. The hashing algorithm [00:01:00] can be chosen depending on your needs and there are many publicly available hashing algorithms. The point is that the algorithm takes the infinite input of bits, applies some calculations to them, and outputs a finite number of bits. For example, 256 bits. What can this hash be used for? A common usage for hashes today is to fingerprint files, also known as check zones. This means that a hash is used to verify that a file has not been [00:01:30] tampered with or modified in any way not intended by the author. If WikiLeaks, for example, publishes a set of files along with their MD5 hashes, whoever downloads those files can verify that they are actually from WikiLeaks by calculating the MD5 hash of the downloaded files, and if the hash doesn't match what was published by WikiLeaks, then you know that the file has been modified in some way. How does the blockchain make use of hashes? [00:02:00] Hashes are used in blockchains to represent the current state of the world. The input is the entire state of the blockchain, meaning all the transactions that have taken place so far and the resulting output hash represents the current state of the blockchain. The hash is used to agree between all parties that the world state is one in the same, but how are these hashes actually calculated? The first hash is calculated for the first block [00:02:30] or the Genesis block using the transactions inside that block. The sequence of initial transactions is used to calculate a block hash for the Genesis block. For every new block that is generated afterwords, the previous block's hash is also used, as well as its own transactions, as input to determine its block hash. This is how a chain of blocks is formed, each new block hash pointing to the block hash that came before it. This system of hashing guarantees that no transaction in the history can be tampered with because if any single part of the transaction changes, so does the hash of the block to which it belongs, and any following blocks' hashes as a result. It would be fairly easy to catch any tampering as a result because you can just compare the hashes. This is cool because everyone on the blockchain only needs to agree on 256 bits to represent the potentially infinite state of the blockchain. The Ethereum blockchain is currently tens of gigabytes, but the current state of the blockchain, as of this recording, is this hexadecimal hash representing 256 bits. What about digital signatures? Digital signatures, like real signatures, are a way to prove that somebody is who they say they are, except that we use cryptography or math, which is more secure than handwritten signatures that can be [00:04:00] easily forged. A digital signature is a way to prove that a message originates from a specific person and no one else, like a hacker. Digital signatures are used today all over the Internet. Whenever you visit a website over ACTPS, you are using SSL, which uses digital signatures to establish trust between you and the server. This means that when you visit Facebook.com, your browser can check the digital signature that came with the web page to verify that it indeed originated from Facebook and not some hacker. In asymmetric encryption systems, users generate something called a key pair, which is a public key and a private key using some known algorithm. The public key and private key are associated with each other through some mathematical relationship. The public key is meant to be distributed publicly to serve as an address to receive messages from other users, like an IP address or home address. The private key is meant to be kept secret and is used to digitally sign messages sent to other users. The signature is included with the message so that the recipient can verify using the sender's public key. This way, the recipient can be sure that only the sender could have sent this message. Generating a key pair is analogous to creating an account on the blockchain, but without having to actually register anywhere. Pretty cool. Also, every transaction that is executed on the blockchain is digitally signed by the sender using their private key. This signature ensures that only the owner of the account can move money out of the account.

Mostly everyone is browsing on the internet to get information nowadays. Let's take a look at some invisible web secrets. Support our Patreon today: https://www.patreon.com/theywillkillyou Subscribe for new videos: http://goo.gl/SaufF4 Follow us on Instagram: @theywillkillyou Known as ‘The Onion Router’ from its original project name, Tor is free software that allows users to communicate on the Internet anonymously. This is achieved by directing traffic through a network of over seven thousand relays that hide the user & their location from traffic analysis & network surveillance. Much like the layers of an onion, Tor implements layered data encryption in its communication protocol. Tor’s main objective is to protect the privacy of its users & to give them the freedom of conducting confidential communication & ensuring that their Internet activities are not being monitored. The software was developed by The Tor Project, Inc, Inc, a nonprofit research & education organization founded by Nick Mathewson, Roger Dingledine & five others. The bulk of their funding came from the United States Government. The Tor Browser, which is a modified & extremely secure version of Mozilla Firefox, is the project’s flagship. For the time being, attacks against Tor fall in the realm of academic research & the software’s developers reportedly welcome any challenge. It is a form of digital currency & a payment system that people all over the world can use to make transactions over the Internet. It's also a type of cryptocurrency which means that the money exchanged can’t be linked to a real identity if the person wants to remain anonymous. Bitcoin is the first decentralized form of currency meaning that the system doesn’t have any administrators or a central repository. The user has a Bitcoin address which is an identifier composed of 26-35 alphanumeric characters & it represents the possible destination of a bitcoin payment. Sites or users need to use a global database known as the blockchain which keeps track of who has how much money at all times. The blockchain is a record of all transactions that have ever been made in the Bitcoin network that also keeps track of newly generated bitcoin. This means that all users know each other’s bitcoin value. The process of generating bitcoins is called mining. The difficulty of the problem increases based on the speed of decryption so that a single block is decrypted every ten minutes. The dark web is not the same thing as the deep web but instead only represents a small part of it. The deep web refers to any site that can’t be accessed through traditional search engines while the dark web represents a part of the deep web that has been hidden intentionally. The most famous content on the dark web can be found in the Tor Network & accessed through Tor browsers. There seems to be no limit what can be found on the dark web. Content includes numerous scams, child pornography, cannibal sites, the sexualized torture & killing of animals, porn that would be banned anywhere else or live torture rooms. Bitcoins may be used to buy anything from fake documents to illegal drugs & weapons or the services of hackers & hitmen. Named after an ancient network of trade routes, the deep web’s Silk Road was an online black market & the first modern darknet market.This means that it could only be accessed with specific configurations, authorization or software. After a development process of 6 months, the Silk Road was launched in February 2011 & it became known as a platform for selling a wide variety of illegal drugs. In October 2013, Ross William Ulbricht, the person suspected of being the Silk Road’s founder under the pseudonym ‘Dread Pirate Roberts’, was arrested by the FBI. He was charged with money laundering, & computer hacking & conspiracy to traffic narcotics & sentenced to life in prison without the possibility of parole. His net worth at the time of his arrest was estimated at $28.5 million. Transactions that took place on the Silk Road were conducted with bitcoins. Circada 3301 was the name attributed to a secret organization that on six occasions published a series of complex puzzles with the purpose of recruiting highly intelligent individuals. Even though the puzzles were posted on different platforms, it was claimed that most of the clues could be found on the deep web. The puzzles focused on steganography, cryptography & data security. Mariana’s Web is an umbrella term used in reference to what lies in the deepest part of the Internet. Some believe that Mariana’s Web is actually an artificial intelligence entity. Others claim that it’s the place where you’ll find the most horrific things available on the deep web.

Cryptocurrency mining malwares are designed to use the computing power of your PC or smartphone, to do someone else’s work of finalizing transactions in cryptocurrencies. If you are a Google Chrome browser user, and you have been using a web browser extension called Archive Poster all this while, chances are your PC would have been hijacked without you even being aware of it, and used for mining cryptocurrencies.. The offending extension, which describes itself as a tool that “allows you to quickly reblog, queue, draft, and like posts right from another blog’s archive” was in fact hijacking the processing power in computers of as many as 105,000 users, and using that to mine cryptocurrencies.. While this particular extension has now been removed from the Chrome web extensions and apps store, it was using a distributed-network cryptocurrency mining program called Coinhive and mining a currency called monero. . If you have been using this extension, it would be a good idea to remove it—head to your Chrome browser app type chrome extensions in address bar look for Archive Poster and click the trash icon next to it to delete.. Bitcoin mining is the process of authenticating and legitimizing bitcoin transactions done online, anywhere in the world. In a simpler scenario, imagine the teller in your bank, who authenticates a deposit or withdrawal transaction that you may make by physically visiting the bank.. In the world of the as-yet-unregulated cryptocurrencies, every single transaction or exchange made using crypto coins needs to be added to what is known as a final bitcoin ledger or blockchain. . These transactions combined then reach “block” status, and it is this block that is sent to miners by different blockchain networks such as bitcoin, litecoin, omni, ripple and in Google Chrome extensions’ case, monero. . The miners who receive these blocks of data that need to be mined then use their specialized hardware and keys called “nonces” to encrypt the block of transaction data. . This hash is then added to the block that was received earlier, thereby authenticating it. Miners are paid when they complete a block.. For this, miners need to invest in very powerful computing devices to execute the mining task. A simple browse through Amazon.com suggests that these aren’t exactly affordable either. . For instance, the popular Bitmain Antminer S9 is priced at $6,399 (around Rs4,07,000) and the DR-100 Pro 21GH/s X11 ASIC Miner costs $1,999. . Considering the money that miners will have to invest initially before any returns start to come in post the successful completion of the mining processes, it perhaps becomes more exciting to write a malware code, piggyback on popular apps, and sneakily use the processing power of thousands or millions of computing devices globally and safely assume that their owners wouldn’t suspect a thing. . The only real give-away is if your PC’s CPU constantly registers 100% or close to 100% usage even when you aren’t

Presentation Slides: http://averageradical.github.io/compile/#/ Send Tips directly to KevG @ bitcoin:1QDEf7xr33aHGPZUHg9WHQkyGLcYKXcv4i Much of the software associated with Bitcoin is open source, i.e. wallets, address generators, mining software, operating systems... Open source means the raw computer code is publicly available for scrutiny. Open source software is usually considered less buggy and more secure. One common obstacle with open source software is transforming it from the raw computer code to a program that runs on your phone, tablet, laptop, desktop. This process is called 'building from source'. This presentation seeks to demonstrate how to build from source several useful applications, with the ability to run these programs on multiple operating systems. Additionally, we will dive into the source code to make small changes prior to building, i.e. background color, edit text, etc... No software development experience necessary.

What is The History of Bitcoin: Super Easy Explanation - https://blockgeeks.com/ We’ll start at the very beginning by understanding the history of blockchain. The very first blockchain in the world was Bitcoin. An anonymous person or group known as Satoshi Nakamoto published a document in an online cryptography forum in November 2008 and revealed the first details of how it would work, describing it as a “peer-to-peer electronic cash system”. The whitepaper is available today at bitcoin.org/bitcoin.pdf. It allows any 2 people to pseudonymously send money to each other no matter where they are in the world. It is a borderless currency. The main benefit of Bitcoin is that it does not require any centralized authority or institution to operate. This is in contrast to today’s centralized financial systems that depend on the existence of a central bank or government to mint money. If for any reason the central authority were to shutdown, the money would become worthless. In a decentralized system like Bitcoin, there is no central authority and the system can continue to operate as long as there are members in its peer-to-peer network. The goal of the whitepaper was to describe how the different parts of the Bitcoin protocol would operate and be kept secure. A new type of database, called a blockchain, would keep track of a single history of all Bitcoin transactions and it would be maintained by everyone in the network. The database would be publicly available for anyone to view and inspect, and anyone can download a copy of the same database. This provides data redundancy and makes sure the data is never lost, but also provides a way for anyone to verify the transactions in the database themselves. A block in the database just stores a sequence of transactions, and a sequence of blocks is called a blockchain. Each block is identified by an incrementing number and a unique Sha-256 hash. The hash for a block is calculated using the transactions inside it, as well as the previous block’s hash, which forms a chain of hashes. The data in the blocks is secured using a cryptographic algorithm called proof-of-work, which also keeps all members of the network and the database in sync to prevent double-spending. In this context, preventing double-spending means preventing anyone from spending money they dont have. Proof-of-work is used to generate new blocks for the database, also known as mining, and the reward for mining a new block is given to the miner by creating new Bitcoins in the system. This is the only way new Bitcoins can be created. Anyone on the network can be a miner and a new block is mined roughly every 10 minutes, which includes the latest set of verified transactions. The first release for Bitcoin was version 0.1 written in C++ by Satoshi and published on SourceForge in January 2009 under the open-source MIT license. Anyone could download the source code and run it to join the network, also known as becoming a node in the network. This is the original version 0.1 source code written by Satoshi. We can see the hard-coded genesis block, which is the very first block in the chain. The hash for the block can be verified by using any Bitcoin blockchain explorer. Let’s copy and paste this hash into the blockchain explorer available at blockchain.info. We can see that this hash is for block number 0, and that it has only one transaction in it which is the mining reward, and the reward amount of 50 Bitcoin was given to this Bitcoin address. We can also see this 50 Bitcoin reward for the genesis block in the original source code. The genesis block is a special case needed to start the blockchain and is the only block that is hard-coded, whereas every subsequent block is calculated using proof-of-work. Satoshi’s motivation for creating Bitcoin is revealed in the piece of data he included in the genesis block: a newspaper headline from The Times that read ‘Chancellor on brink of second bailout for banks’. The date of the newspaper is proof that the genesis block was created on or after Jan 3 2009. Satoshi developed the source code mostly himself up until mid-2010, when he handed it off to the open-source community. It is now maintained under the project called Bitcoin Core. The software is currently at version 0.15.1 and is available for download at bitcoin.org. This is still the most popular Bitcoin client, and its estimated that there are over 10 thousand nodes running the Bitcoin network today using various clients. Satoshi disappeared from public view in late 2010, his identity still unknown to this day. The only way someone could prove that they are Satoshi is by using the same encryption keys used when posting the original whitepaper in the online cryptography forum.

Critical study on Data Mining with IDSS using RAPID technique for Diabetes To get this project in ONLINE or through TRAINING Sessions, Contact: JP INFOTECH, #37, Kamaraj Salai,Thattanchavady, Puducherry -9. Mobile: (0)9952649690, Email: [email protected], Website: http://www.jpinfotech.org In data mining, knowledge is extracted using key elements and concepts after identifying relevant and reliable data. But in the field of health care, researchers are finding it difficult to convert the bio-medical database into knowledge at a rapid pace. The medical data is huge, complex and heterogeneous in nature. Data Mining principles& tools are used in conjunction with health care expert systems to extract inherent relationships among data elements as knowledge. By integrating different data mining concepts with expert systems, a new system called “Integrated Decision Support System” (IDSS) is proposed, which can provide better results compared to existing ones. It converts knowledge into useful format and uses different tools for construction of its architecture. To reduce possible solutions for diabetic diagnosis, Case Based Reasoning (CBR), Rule Based Reasoning (RBR) and Web Based Portal Joint Asia Diabetes Evaluation( JADE) programs are integrated with Reliable Access and Probabilistic Inference based on clinical Data (RAPID) in the developed IDSS system to enhance existing systems for fast extraction of knowledge.

Mobile: (0) 9952649690, Email: [email protected], web: http://www.jpinfotech.org Searchable encryption allows a cloud server to conduct keyword search over encrypted data on behalf of the data users without learning the underlying plaintexts. However, most existing searchable encryption schemes only support single or conjunctive keyword search, while a few other schemes that are able to perform expressive keyword search are computationally inefficient since they are built from bilinear pairings over the composite-order groups. In this paper, we propose an expressive public-key searchable encryption scheme in the prime-order groups, which allows keyword search policies (i.e., predicates, access structures) to be expressed in conjunctive, disjunctive or any monotonic Boolean formulas and achieves significant performance improvement over existing schemes. We formally define its security, and prove that it is selectively secure in the standard model. Also, we implement the proposed scheme using a rapid prototyping tool called Charm, and conduct several experiments to evaluate it performance. The results demonstrate that our scheme is much more efficient than the ones built over the composite-order groups.

Blockchain is a kind of tamper resistant digital ledger. The ledger stores data in groupings called "blocks." What data gets stored in the blocks depends on what the blockchain is being used for (whether it's to transfer digital currency, or to store and distribute other transaction information like real estate or medical records, and so on). Also stored in the blocks is an encrypted digital fingerprint, or hash, that identifies the block and what data is inside it. Each newly generated block also contains the previously generated block's digital fingerprint such that the blocks can be sequentially linked or "chained" together, hence the term "blockchain." Tampering with the data inside any block within the chain is therefore difficult, in part because such tampering would constitute an alteration of the block's digital fingerprint, thereby risking the unlinking of the block and the breaking of the chain. One major benefit of blockchain is that the generation, or "mining" of such blocks and their distribution is decentralized. So it would be unlikely that any one entity could control the blockchain network, given that the network is supposed to be comprised of many individual users, or "peers." Blockchain technology gained more visibility due to Bitcoin, a blockchain cryptocurrency originally developed by a mysterious figure who went by the name "Satoshi Nakamoto." Attention to Bitcoin reached its height in 2017 and 2018 as its value in dollars grew rapidly and then crashed. Other cryptocurrencies have also seen ups and downs such as Ethereum, the second largest cryptocurrency and blockchain network after Bitcoin. Blockchain is a tool; like any tool it could be used for public benefit or for harm. But if we want to cultivate prosocial uses for blockchain, more people will need to understand what it is and how it works. That's why we talked to Soumya Basu. Soumya is a Computer Science PhD student, who researches blockchain at Cornell University. Soumya is also the co-founder and Chief Technology Officer of bloXroute, a distribution network meant effectively to increase blockchains' number of transactions per second.

Random forest algorithm is a one of the most popular and most powerful supervised Machine Learning algorithm in Machine Learning that is capable of performing both regression and classification tasks. As the name suggest, this algorithm creates the forest with a number of decision trees. In general, the more trees in the forest the more robust the prediction. In the same way in the random forest classifier, the higher the number of trees in the forest gives the high accuracy results. To model multiple decision trees to create the forest you are not going to use the same method of constructing the decision with information gain or gini index approach, amongst other algorithms. If you are not aware of the concepts of decision tree classifier, Please check out my lecture here on Decision Tree CART for Machine learning. You will need to know how the decision tree classifier works before you can learn the working nature of the random forest algorithm. ------------------------------------------------------------ Support us on Patreon ►AugmentedStartups.info/Patreon Chat to us on Discord ►AugmentedStartups.info/discord Interact with us on Facebook ►AugmentedStartups.info/Facebook Check my latest work on Instagram ►AugmentedStartups.info/instagram Learn Advanced Tutorials on Udemy ►AugmentedStartups.info/udemy ------------------------------------------------------------ To learn more on Artificial Intelligence, Augmented Reality IoT, Deep Learning FPGAs, Arduinos, PCB Design and Image Processing then check out http://augmentedstartups.info/home Please Like and Subscribe for more videos :)

What's the big buzz about **Cryptocurrency**. Even I came to know a few days ago, That's why I wanna share my understanding with you and if I'm wrong at any point please feel free to correct me.Let's begin :-) Cryptocurrency is an encrypted decentralized digital currency transferred between peers and confirmed in a public ledger via a process known as mining. ## Buzz words: **Public Ledgers:** All confirmed transactions from the start of a cryptocurrency’s creation are stored in a public ledger. The identities of the coin owners are encrypted, and the system uses other cryptographic techniques to ensure the legitimacy of record keeping. **Transactions:** A transfer of funds between two digital wallets is called a transaction. That transaction gets submitted to a public ledger and awaits confirmation. When a transaction is made, wallets use an encrypted electronic signature (an encrypted piece of data called a cryptographic signature) to provide a mathematical proof that the transaction is coming from the owner of the wallet. **Mining:** In simple terms, mining is the process of confirming transactions and adding them to a public ledger. In order to add a transaction to the ledger, the “miner” must solve an increasingly-complex computational problem (sort of like a mathematical puzzle). The mining process is what gives value to the coins and is known as a proof-of-work system. ***OMG!!!*** Cryptocurrencies are typically open source. That means that developers can create APIs without paying a fee and anyone can use or join the network. The transaction is known almost immediately by the whole network. But only after a specific amount of time it gets confirmed. Confirmation is a critical concept in cryptocurrencies. You could say that cryptocurrencies are all about confirmation. As long as a transaction is unconfirmed, it is pending and can be forged. When a transaction is confirmed, it is set in stone. It is no longer forgeable, it can‘t be reversed, it is part of an immutable record of historical transactions: of the so-called blockchain. On a blockchain, transactions are recorded chronologically, forming an immutable chain, and can be more or less private or anonymous depending on how the technology is implemented. The ledger is distributed across many participants in the network — it doesn’t exist in one place. Instead, copies exist and are simultaneously updated with every fully participating node in the ecosystem. Only miners can confirm transactions. This is their job in a cryptocurrency-network. They take transactions, stamp them as legit and spread them in the network. After a transaction is confirmed by a miner, every node has to add it to its database. It has become part of the blockchain. For this job, the miners get rewarded with a token of the cryptocurrency, for example with Bitcoins. Since the miner‘s activity is the single most important part of cryptocurrency-system we should stay for a moment and take a deeper look on it. Principally everybody can be a miner. Since a decentralized network has no authority to delegate this task, a cryptocurrency needs some kind of mechanism to prevent one ruling party from abusing it. Imagine someone creates thousands of peers and spreads forged transactions. The system would break immediately. So,there is a rule that the miners need to invest some work of their computers to qualify for this task. In fact, they have to find a hash – a product of a cryptographic function – that connects the new block with its predecessor. This is called the Proof-of-Work. Proof of work is a protocol that has the main goal of deterring cyber-attacks such as a distributed denial-of-service attack (DDoS) which has the purpose of exhausting the resources of a computer system by sending multiple fake requests. ## Pros - Cryptocurrencies make it easier to transfer funds between two parties in a transaction. These transfers are facilitated through the use of public and private keys for security purposes. These fund transfers are done with minimal processing fees, allowing users to avoid the steep fees charged by most banks and financial institutions for wire transfers. ## Cons: - Because cryptocurrencies are virtual and do not have a central repository, a digital cryptocurrency balance can be wiped out by a computer crash if a backup copy of the holdings does not exist. - Since prices are based on supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can fluctuate widely.

Hi, I’m Sy “The IT Guy” Williams, the owner of TeamLogic IT of Orlando In the previous video I provided an overview of Blockchain. In this video I’m going to discuss How Blockchains Work The Role of Miners Blockchain Immutability A blockchain is a peer-to-peer network that consist of wallets and nodes. A wallet can be a mobile or web based application. It has an address that can be the source and destination of a transaction. Wallets are used to create transactions, cryptographically sign the transactions, and communicate the transaction to the nearest node. All full nodes (called miners) receive all transactions either from a wallet or from a peer. Each node node will validate the transaction and bundle it with other transactions to create a block of transactions. Each new block is connected to the previous block by placing the hash value of the previous block into the new block. The logging of the previous block hash value is what creates the chain. A hash is a fixed length cryptographic representation of the data. When the node finds a specific hash value for the block it is creating it will add that block to its local copy of the blockchain. The node will notify peers that it has successfully created a new block. All peers will validate the new block before accepting it/adding it to its local copy of the blockchain. A hash is an algorithm that takes data input of any lengths and derives a unique fixed length output. A hash can be thought of as a fingerprint of the data. The creation of the hash is a one-way process meaning you can convert data to a hash but you can not take the hash value and convert it back to the data. The National Institute of Science and Technology (NIST) has published secure hash algorithms (SHA). Bitcoin uses secure hash algorithm SHA-256 and Ethereum uses secure hash algorithm SHA-3. The one-way translation provides a mechanism to validate data without revealing it. Public-key encryption uses two mathematically related keys: a public key known to everyone and a private key known only to the recipient of a message Your public key is used to encrypt the message and can be shared Your private key is used to decrypt messages, sign transactions, and should remain private. All transactions are digitally signed using private keys. All blocks are linked to the previous block via the previous block hash Any change to a block will change the block’s hash and invalidate succeeding blocks Invalid blocks won’t be accepted by other nodes in the blockchain network The other nodes will not add this change to their local copy of the blockchain

In this talk, we'll go through our project called NuCypher, a network to empower privacy and data confidentiality in decentralized systems based on the use of advanced cryptographic techniques. In particular, we use "proxy re-encryption", a special type of cryptosystem that allows to delegate decryption rights of encrypted information. Nodes in our network provide a cryptographically-enforced access control service that allows users to securely share information with others, but in such a way that nodes are completely oblivious to the data that is encrypted: at no point nodes can read anything. We'll cover how Python has enabled the vast majority of our implementation, from constructing a low-level library for elliptic curve arithmetic on top of cryptography.io, to interacting with the Ethereum blockchain with py-geth and web3.py. Finally, you'll see a practical example of the use of pyUmbral, our cryptographic library (https://github.com/nucypher/pyUmbral), and a live demo of how to share data securely with the NuCypher network.

However, the use of LBS also poses a potential threat to user’s location privacy. In this paper, aiming at spatial range query, a popular LBS providing information about points of interest (POIs) within a given distance, we present an efficient and privacy-preserving location-based query solution, called EPLQ. Specifically, to achieve privacy preserving spatial range query, we propose the first predicate-only encryption scheme for inner product range (IPRE), which can be used to detect whether a position is within a given circular area in a privacy-preserving way. To reduce query latency, we further design a privacy-preserving tree index structure in EPLQ. Detailed security analysis confirms the security properties of EPLQ. In addition, extensive experiments are conducted, and the results demonstrate that EPLQ is very efficient in privacy preserving spatial range query over outsourced encrypted data. In particular, for a mobile LBS user using an Android phone, around 0.9 s is needed to generate a query, and it also only requires a commodity workstation, which plays the role of the cloud in our experiments, a few seconds to search POIs.

Hi and welcome to our channel! So you’ve been told crypto is perfect for concealing your identity when transacting? A lot of people think cryptocurrencies are inherently anonymous. But this is not entirely true. Most are rather pseudonymous. Take Bitcoin for example. One can track all transactions associated with an address. Bitcoin transactions are linked to a specific address which makes up an “identity” of sorts, much like an IP address. However, there are multiple solutions for those seeking enhanced privacy. Monero, Dash and Zcash, for instance. Today we’re going to be breaking down the latter. Zcash is a Bitcoin fork. As a result it has the same total supply of coins, and each is made up of smaller units called zatoshis in reference to Bitcoin’s satoshis. Zcash’s genesis block was mined back in 2016, but there was no ICO or premine. But let’s first take a look at the people who created this coin and are maintaining its infrastructure. 0:59 Zcash Team There’s an officially registered entity developing Zcash – the Zerocoin Electric Coin Company. Zooko Wilcox is the creator of the coin and CEO of the company. He boasts 20 years of experience in cryptography and distributed ledgers. He’s always been a fan of Bitcoin, but he wished for more discretion. Another prominent member of the Zcash team goes by the name of Matthew Green. He’s a cryptographer and security technologist at the Johns Hopkins Information Security Institute. There are a number of other scientists from Berkeley and Tel Aviv University, but who are also important to mention are Vitalik Buterin of Ethereum, Gavin Andresen of Bitcoin Core and Tezos founder Arthur Breitman. 1:36 Technolgy Behind Zcash ZCash employs a cryptographic tool called zk-SNARK which stands for Zero-Knowledge Succinct Non-Interactive Argument of Knowledge aka Zero Knowledge Proof for short. It verifies transactions without giving away its participants (their public addresses) and the amount being transferred. If you opt for it, that is, because there’s an option to reveal all that data to whomever you see appropriate. And it keeps this data on the blockchain fully encrypted which renders a transaction virtually intractable. As a side note, the protocol was really developed in the 1980s by researchers of Massachusetts Institute of Technology. 2:10 Mining The hashing algorithm used by Zcash is a type of proof-of-work algorithm called Equihash and it was introduced specifically for this cryptocurrency in 2016. It is memory-oriented which is different with Bitcoin. And even though graphics cards are still a viable option for mining Zcash, numerous ASIC devices have emerged that eventually broke the whole purpose of integrating Equihash. One block generates within 2.5 minutes, and 12.5 ZEC are issued per one block. But here’s something to take into account. 80% of the mined coins go to the miner, while the remaining 20% go to a special pool referred to as "founders' reward". It is shared between investors, developers, and the Zcash Foundation. 2:50 Pros & Cons This cryptocurrency isn’t perfect, of course, and arguably not even the best among its counterparts, but there are a few upsides that we’d like to highlight. #1 Anonymity due to the blockchain only recording timestamps of transactions, when users select to use all the privacy features to the fullest degree. And the level of transactions’ transparency is customizable. #2 Fungibility. Every single unit of the currency isn’t marked, so you can’t determine if, where and when it’s been used before. Some merchants will not accept Bitcoin that have previously been used for some illegal purposes. #3 Efficient mining relative to Bitcoin. Graphics cards don’t consume as much energy as ASICs do, if again you choose to go for the card option. Now let’s touch upon some drawbacks of Zcash. #1 Speed. It takes 2.5 minutes to generate one block, and one second to process 6-25 transactions. For comparison, Dash, another anonymous coin, can do so much better due to its InstantSend feature. #2 Its privacy-oriented technology needs to be tested by time. There was an occurrence last year that filled many Zcash fans with doubt about its reliability when paying on the darkweb. We’re talking about Seizure of AlphaBay by law enforcement agencies just days after the announcement it would accept Zcash. As a separate point we’d like to bring up the price dynamics. The average rate in October 2018 was $116 which is a huge decline since the first day of the coin’s existence when it was worth over $4,200. On the bright side, it’s become so popular now that you can purchase it on most of the top-rated marketplaces such as Binance, Bithumb, Bittrex and Bitfinex. #zcash #crypto #cryptotimes #anonymous #investment #monero

What is Bitcoin? Well, that is not the correct question to ask. Bitcoin is a cryptocurrency so better ask What is a Cryptocurrency and How Does it Works ? A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions, to control the creation of additional units, and to verify the transfer of assets.] Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies. How bitcoin works? As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once. Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography. Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining. Processing - mining Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spend

However, cloud storage gives rise to security concerns. In case of group-shared data, the data face both cloud-specific and conventional insider threats. Secure data sharing among a group that counters insider threats of legitimate yet malicious users is an important research issue. In this paper, we propose the Secure Data Sharing in Clouds (SeDaSC) methodology that provides: 1) data confidentiality and integrity; 2) access control; 3) data sharing (forwarding) without using compute-intensive reencryption; 4) insider threat security; and 5) forward and backward access control. The SeDaSC methodology encrypts a file with a single encryption key. Two different key shares for each of the users are generated, with the user only getting one share. The possession of a single share of a key allows the SeDaSC methodology to counter the insider threats. The other key share is stored by a trusted third party, which is called the cryptographic server. The SeDaSC methodology is applicable to conventional and mobile cloud computing environments. We implement a working prototype of the SeDaSC methodology and evaluate its performance based on the time consumed during various operations. We formally verify the working of SeDaSC by using high-level Petri nets, the Satisfiability Modulo Theories Library, and a Z3 solver. The results proved to be encouraging and show that SeDaSC has the potential to be effectively used for secure data sharing in the cloud.

Title: Extracting Spread-Spectrum Hidden Data from Digital Media Domain: Networking - Steganography Key Features: 1. We consider the problem of extracting blindly data embedded over a wide band in a spectrum (transform) domain of a digital medium (image, audio, video). We develop a novel multicarrier/ signature iterative generalized least-squares (M-IGLS) core procedure to seek unknown data hidden in hosts via multicarrier spread-spectrum embedding. 2. Neither the original host nor the embedding carriers are assumed available. Experimental studies on images show that the developed algorithm can achieve recovery probability of error close to what may be attained with known embedding carriers and host autocorrelation matrix. 3. We propose the information hiding concept to reduce the risk of using cryptographic algorithms alone. Data hiding techniques embed information into another medium making it imperceptible to others, except for those that are meant to receive the hidden information and are aware of it presence. 4. It focuses on methods of hidden data in which cryptographic algorithms are combined with the information hiding techniques to increase the security of transmitted data. We focus our attention on the blind recovery of secret data hidden in medium hosts via multi-carrier/signature direct-sequence spread-spectrum transform domain embedding. MODULE DESCRIPTION Steganography: Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol Digital steganography can hide confidential data (i.e. secret files) very securely by embedding them into some media data called "vessel data." The vessel data is also referred to as "carrier, cover, or dummy data". In Steganography images used for vessel data. The embedding operation in practice is to replace the "complex areas" on the bit planes of the vessel image with the confidential data. The most important aspect of Steganography is that the embedding capacity is very large. For a 'normal' image, roughly 50% of the data might be replaceable with secret data before image degradation becomes apparent. Multi-Carrier Spread Spectrum Embedding: The technique of spread spectrum may allow partly to fulfill the above requirements. Advantages of spread spectrum techniques are widely known: Immunity against multi-path distortion, no need for fiequency planning, high flexibility and variable data rate transmission. The capability of minimising multiple access interference in direct-sequence code- division-multiple-access system is given by the cross-correlation properties of spreading codes. In the case of multi-path propagation the capability of distinguishing one component fiom thers in the composite received signal is offered by the auto-correlation roperties of the spreading codes. Image encryption and watermarking: The host image is an 8-bit or higher grey level image which must ideally be the same size as the plaintext image or else resized accordingly using the same proportions. Pre-conditioning the cipher and the convolution processes are undertaken using a Discrete Fourier Transform (DFT). The output will include negative floating point numbers upon taking the real component of a complex array. The array must be rectified by adding the largest negative value in the output array to the same array before normalization. For color host images, the binary cipher text can be inserted into one or all of the RGB components. The binary plaintext image should have homogeneous margins to minimize the effects of ringing due to 'edge effects' when processing the data using Fourier transform. Image decryption and extraction: (i) The correlation operation should be undertaken using a DFT. (ii) For color images, the data is decomposed into each RGB component and each 1-bit layer is extracted and correlated with the appropriate cipher. (iii) The output obtained in Step 3 has a low dynamic range and therefore requires to be quantized into an 8-bit image based on floating point numbers within the range max (array)-min (array).

However, the use of LBS also poses a potential threat to user’s location privacy. In this paper, aiming at spatial range query, a popular LBS providing information about points of interest (POIs) within a given distance, we present an efficient and privacy-preserving location-based query solution, called EPLQ. Specifically, to achieve privacy preserving spatial range query, we propose the first predicate-only encryption scheme for inner product range (IPRE), which can be used to detect whether a position is within a given circular area in a privacy-preserving way. To reduce query latency, we further design a privacy-preserving tree index structure in EPLQ. Detailed security analysis confirms the security properties of EPLQ. In addition, extensive experiments are conducted, and the results demonstrate that EPLQ is very efficient in privacy preserving spatial range query over outsourced encrypted data. In particular, for a mobile LBS user using an Android phone, around 0.9 s is needed to generate a query, and it also only requires a commodity workstation, which plays the role of the cloud in our experiments, a few seconds to search POIs.

Your files are encrypted, shredded into little pieces called 'shards', and stored in a decentralized network of computers around the globe. No one but you has a complete copy of your file, not even in an encrypted form. Because of this, Storj can be faster, cheaper, and more secure than traditional cloud storage platforms. Faster because multiple machines are serving you your file simultaneously, cheaper because you are renting people's spare hard-drive space instead of paying for a purpose-built data center, and more secure because your file is both encrypted and shredded. There is no need to trust a corporation, vulnerable servers, or employees with your files. Storj completely removes trust from the equation. Storj uses blockchain features like a transaction ledger, public/private key encryption, and cryptographic hash functions for security. Storj is working hard to solve data security issues with the help of its own web app, Storj, which lets you store your files, and client app, Storj Share, which lets you rent your hard-drive space for money. To best protect your data, files are encrypted client-side on your computer before they are uploaded. Each file is split up into chunks which are first encrypted and then distributed for storage across the Storj network. The network is comprised of Storj Share nodes run by users around the world who rent out their unused hard drive space in return for Storjcoin X coin. The decentralized aspect of Storj means there are no central servers to be compromised, and with client-side encryption, you are in control of the keys to your files. Storj team recently announced migration to Ethereum blockchain. Migration will happen 1 to 4 weeks after the second crowdsale is finished. Well the second crowdsale is finished and the goal of raising 30 million $ for the future development is reached! If you check any other project on Ethereum blockchain, they all have much bigger market cap value than Storj has today, so we can expect a huge price increasement once STORJ is connected to Ethereum blockchain. Migration to Ethereum blockchain also means "smart contracts" as a new tool for Storj team to help them accomplish even bigger decentralization, primarily when it comes to payments. With migration to Ethereum a huge potential lies in a fact that some of the projects build on Ethereum blockchain will now easily connect and start using Storj as a storage solution for hosting their files. I hope this video will help you understand the huge potential of Storj and will trigger you to invest into Storj before the migration happens! Once the migration happens you will be late as the price will reach the skies!

Cloud computing provides a flexible and convenient way for data sharing, which brings various benefits for both the society and individuals. But there exists a natural resistance for users to directly outsource the shared data to the cloud server since the data often contain valuable information. Thus, it is necessary to place cryptographically enhanced access control on the shared data. Identity-based encryption is a promising cryptographical primitive to build a practical data sharing system. However, access control is not static. That is, when some user’s authorization is expired, there should be a mechanism that can remove him/her from the system. Consequently, the revoked user cannot access both the previously and subsequently shared data. To this end, we propose a notion called revocable-storage identity-based encryption (RS-IBE), which can provide the forward/backward security of ciphertext by introducing the functionalities of user revocation and ciphertext update simultaneously. Furthermore, we present a concrete construction of RS-IBE, and prove its security in the defined security model. The performance comparisons indicate that the proposed RS-IBE scheme has advantages in terms of functionality and efficiency, and thus is feasible for a practical and cost-effective data-sharing system. Finally, we provide implementation results of the proposed scheme to demonstrate its practicability. To Get the Source code contact 9003628940 [email protected]

http://CppCon.org Niek J. Bouman “Multi-Precision Arithmetic for Cryptology in C++, at Run-Time and at Compile-Time” — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — In the talk, I will present a new C++17 library for multi-precision arithmetic for integers in the order of 100--500 bits. Many cryptographic schemes and applications, like elliptic-curve encryption schemes and secure multiparty computation frameworks require multiprecision arithmetic with integers whose bit-lengths lie in that range. The library is written in “optimizing-compiler-friendly” C++, with an emphasis on the use of fixed-size arrays and particular function-argument-passing styles (including the avoidance of naked pointers) to allow the limbs to be allocated on the stack or even in registers. Depending on the particular functionality, we get close to, or significantly beat the performance of existing libraries for multiprecision arithmetic that employ hand-optimized assembly code. Beyond the favorable runtime performance, our library is, to the best of the author’s knowledge, the first library that offers big-integer computations during compile-time. For example, when implementing finite-field arithmetic with a fixed modulus, this feature enables the automatic precomputation (at compile time) of the special modulus- dependent constants required for Barrett and Montgomery reduction. Another application is to parse (at compile-time) a base-10-encoded big-integer literal. In this talk, I will focus on some Modern C++ language features that I've used to write the library and design its API (e.g., std::array, variadic templates, std::integer_sequence, constexpr, user-defined literals, using-declarations and decltype, and combinations thereof). Also, I will show some benchmarks, and will argue that the integer types offered by the library compose well with STL containers or other libraries (like Eigen for matrix/linear algebra operations). I will also present some results on formal verification of correctness and the "constant-time" property: - Correctness is verified using a tool named SAW (Software Analysis Workbench), which tries to prove equivalence between the compiled C++ code (represented as LLVM bitcode) and a behavioral specification given in a high-level functional language; - "Constant-timeness" is a property that is crucial for implementations of cryptographic protocols to prevent timing attacks. In particular, I succeeded to verify my C++ code with "ct-verif", a tool for verifying the constant-time property for C programs (which was, in its original form, incompatible with C++ due to usage of non-ANSI C in one of its header files) The library is on Github (Apache 2 licensed) https://github.com/niekbouman/ctbignum — Niek J.

BLOCKCHAIN: Blockchain Beginner's Explained - Blockchain Review ★ CONTACTS ➤ [email protected] Just what is Blockchain Blockchain, the underlying modern technology that powers bitcoin, is just one of the buzzwords of the previous year. Almost everybody is speaking about blockchain, and also forever factor. Dispersed journals, the regard to art for blockchain's underlying modern technology, supply an amazing brand-new means to negotiate organisation without a main authority. Below's a nontechnical, streamlined summary of the part. Blockchain specified A blockchain, or dispersed journal, is a constantly expanding checklist (electronic documents) of encrypted purchases called "blocks" that are dispersed (duplicated) to a peer-to-peer (P2P) network of computer systems. Blocks As defined over, a blockchain is an unalterable, consecutive chain of documents referred to as blocks. A block could consist of any type of sort of information, such as one-of-a-kind electronic identifiers of physical items. Blocks are "chained" with each other utilizing hashes. A hash is a feature that takes an input worth and also from that input develops an outcome worth deterministic of the input worth. Along with individual information, each block will certainly include an index, a timestamp, a listing of purchases, an evidence as well as the hash of the previous block. The hash The hash plays an important duty. Since each brand-new block will certainly consist of a hash of the previous block, blockchains are unalterable. If a cyberpunk were to corrupt an earlier block in the blockchain, all succeeding blocks would certainly have inaccurate hashes. Encrypted purchases Encrypted purchases (making use of traditional public/private essential cryptography) are likewise vital to blockchain's worth. The customer's "public secret" is kept in a block as well as comes to be an "address" on the blockchain. Documents such as cryptocurrencies or various other electronic properties are taped as coming from a certain block. An equivalent "exclusive trick" is called for to access the linked electronic properties. Maintaining your exclusive crucial personal is so vital that to secure their electronic properties from cyberpunks, many individuals do not maintain electronic duplicates of their personal secrets. They compose the number on a paper as well as maintain the paper in a safe area (like a wall surface secure). Evidence of Job (PoW). When a blockchain is instantiated, an Evidence of Job formula (PoW) is made use of to develop or "mine" brand-new blocks. The existing bitcoin mining method offers a fine example of PoW use. This strategy is explained in Wikipedia as complies with: "A bitcoin miner runs a computer system program that gathers unofficial purchases from coin dealerships in the network. With various other information these could create a block as well as gain a settlement to the miner, however a block is approved by the network just when the miner finds by experimentation a 'nonce' number that when consisted of in the block generates a hash with an enough variety of leading absolutely no little bits to fulfill the network's problem target. Blocks approved from miners develop the bitcoin blockchain that is an expanding journal of every bitcoin purchase because the coin's initial development.". Public or exclusive. There are 2 basic sorts of blockchain networks: confidential networks, where each customer has a duplicate of the whole blockchain as well as assists procedure and also verify purchases; as well as permission-based (non-anonymous) networks, where consent is called for to have a duplicate of the blockchain as well as in order to help procedure as well as verify deals. Besides cryptocurrencies, just what can you make with blockchain? Blockchain provides a means to validate purchases without the requirement for a main authority. This implies you could develop clever agreements making use of dispersed journals. For instance, a proprietor may place an IoT door lock on your rental house. The door lock could examine the blockchain to see if your lease is paid. If it isn't really, the door lock (that is, the wise agreement) would certainly not allow you right into the home. In an extra complicated situation, a company can release its very own bonds and also purchasers can keep track of settlements by means of a dispersed journal. A much more complicated usage situation would certainly be the production of self-enforcing profession arrangements. The listing of usages for blockchain is virtually limitless. From title searches to shipment confirmation, dispersed journals provide a totally brand-new, safe and secure means to do company. Your essential inquiry is: "For this job, is a blockchain a far better selection compared to a well-crafted, safe data source?" Afterwards, you get on your method!
