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.

Once the encryption key is exposed, the only viable measure to preserve data confidentiality is to limit the attacker’s access to the ciphertext. This may be achieved, for example, by spreading ciphertext blocks across servers in multiple administrative domains—thus assuming that the adversary cannot compromise all of them. Nevertheless, if data is encrypted with existing schemes, an adversary equipped with the encryption key, can still compromise a single server and decrypt the ciphertext blocks stored therein. In this paper, we study data confidentiality against an adversary which knows the encryption key and has access to a large fraction of the ciphertext blocks. To this end, we propose Bastion, a novel and efficient scheme that guarantees data confidentiality even if the encryption key is leaked and the adversary has access to almost all ciphertext blocks. We analyze the security of Bastion, and we evaluate its performance by means of a prototype implementation. We also discuss practical insights with respect to the integration of Bastion in commercial dispersed storage systems. Our evaluation results suggest that Bastion is well-suited for integration in existing systems since it incurs less than 5% overhead compared to existing semantically secure encryption modes.

This is part 10 of the Blockchain tutorial explaining how the Diffie-Hellman key exchange works. 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.

Key-Aggregate Searchable Encryption (KASE) for Group Data Sharing via Cloud Storage To get this project in ONLINE or through TRAINING Sessions, Contact:JP INFOTECH, Old No.31, New No.86, 1st Floor, 1st Avenue, Ashok Pillar, Chennai -83.

Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com ABSTRACT: The capability of selectively sharing encrypted data with different users via public cloud storage may greatly ease security concerns over inadvertent data leaks in the cloud. A key challenge to designing such encryption schemes lies in the efficient management of encryption keys. The desired flexibility of sharing any group of selected documents with any group of users demands different encryption keys to be used for different documents. However, this also implies the necessity of securely distributing to users a large number of keys for both encryption and search, and those users will have to securely store the received keys, and submit an equally large number of keyword trapdoors to the cloud in order to perform search over the shared data. The implied need for secure communication, storage, and complexity clearly renders the approach impractical. In this paper, we address this practical problem, which is largely neglected in the literature, by proposing the novel concept of key aggregate searchable encryption (KASE) and instantiating the concept through a concrete KASE scheme, in which a data owner only needs to distribute a single key to a user for sharing a large number of documents, and the user only needs to submit a single trapdoor to the cloud for querying the shared documents. The security analysis and performance evaluation both confirm that our proposed schemes are provably secure and practically efficient.

Secure Overlay Routing Using Key Pre-Distribution: A Linear Distance Optimization Approach To get this project in ONLINE or through TRAINING Sessions, Contact: JP INFOTECH, Old No.31, New No.86, 1st Floor, 1st Avenue, Ashok Pillar, Chennai -83.Landmark: Next to Kotak Mahendra Bank. Pondicherry Office: JP INFOTECH, #45, Kamaraj Salai,Thattanchavady, Puducherry -9.Landmark: Next to VVP Nagar Arch. Mobile: (0) 9952649690, Email: [email protected], web: http://www.jpinfotech.org, Blog: http://www.jpinfotech.blogspot.com Key pre-distribution algorithms have recently emerged as efficient alternatives of key management in today’s secure communications landscape. Secure routing techniques using key pre-distribution algorithms require special algorithms capable of finding optimal secure overlay paths. To the best of our knowledge, the literature of key pre-distribution systems is still facing a major void in proposing optimal overlay routing algorithms. In the literature work, traditional routing algorithms are typically used twice to find a NETWORK layer path from the source node to the destination and then to find required cryptographic paths. In this paper, we model the problem of secure routing using weighted directed graphs and propose a boolean linear programming (LP) problem to find the optimal path. Albeit the fact that the solutions to boolean LP problems are of much higher complexities, we propose a method for solving our problem in polynomial time. In order to evaluate its performance and security measures, we apply our proposed algorithm to a number of recently proposed symmetric and asymmetric key pre-distribution methods. The results show that our proposed algorithm offers great network performance improvements as well as security enhancements when augmenting baseline techniques.

SoK: Research Perspectives and Challenges for Bitcoin and Cryptocurrencies Joseph Bonneau Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT Bit coin has emerged as the most successful cryptographic currency in history. Within two years of its quiet launch in 2009, Bit coin grew to comprise billions of dollars of economic value despite only cursory analysis of the system's design. Since then a growing literature has identified hidden-but-important properties of the system, discovered attacks, proposed promising alternatives, and singled out difficult future challenges. Meanwhile a large and vibrant open-source community has proposed and deployed numerous modifications and extensions. We provide the first systematic exposition Bit coin and the many related crypto currencies or 'altcoins.' Drawing from a scattered body of knowledge, we identify three key components of Bit coin's design that can be decoupled. This enables a more insightful analysis of Bit coin's properties and future stability. We map the design space for numerous proposed modifications, providing comparative analyses for alternative consensus mechanisms, currency allocation mechanisms, computational puzzles, and key management tools. We survey anonymity issues in Bit coin and provide an evaluation framework for analyzing a variety of privacy-enhancing proposals. Finally we provide new insights on what we term disinter mediation protocols, which absolve the need for trusted intermediaries in an interesting set of applications. We identify three general disinter mediation strategies and provide a detailed comparison.

Here is a Metaphor video that explains this concept in easy way. Hope you will like it!!! What is Homomorphic Encryption and why I should care? THE PROBLEM WITH encrypting data is that sooner or later, you have to decrypt it as soon as you want to actually do something with those files—anything from editing a word document or querying a database of financial data—you have to unlock the data and leave it vulnerable. Homomorphic encryption, a still-mostly-theoretical advancement in the science of keeping secrets, could change that. For, example suppose Sara wants to add 1,2 but she doesn't know about how to add numbers. she asked john to add the numbers, but she doesn't trust john ,so she Encrypt the numbers (1,2) into another numbers 33,54 and sends these numbers to john. Jhon ,who only has access to the Encrypted data set,finds the sum of 33+45 and returns the answer 87 to Sara. Sara decrypts the Johns reply and finds the answer 3. So Homomorphic Encryption is a form of Encryption where you can perform operations on to encrypted text and get the encrypted result, which when decrypted would be same as you would get if the operation was performed on the decrypted text in the first place. Like performing addition of enc(2) and enc(3) would give you enc(2+3),which when decrypted would give you answer as 5 The way we understand The underlying idea , it is: Sara to be able to send encrypted data out,john to have certain code operate on this encrypted data and have the end result sent back to Sara, in a way that: it allows Sara to decrypt the end result,and does not allow anyone else to understand what is it about.

Using the TPM NVRAM to Protect Secure Boot Keys in POWER9 OpenPOWER Systems - Claudio Siqueira de Carvalho, IBM In OpenPOWER systems, most firmware code used to boot the platform OS is stored in the processor flash memory (PNOR). Although PNOR is non-volatile memory, it is unprotected. In order to secure boot the platform OS, it is well known that only platform OSs signed with authorized keys should booted. However, saving the authorized keys in a secure non-volatile memory is as important as using them to verify the platform OS. In this presentation, Claudio Carvalho will show how the shielded non-volatile memory (NVRAM) of the Trusted Platform Module (TPM) has become essential in OpenPOWER systems to protect the secure boot keys stored in PNOR. This discussion includes design and implementation aspects that are both currently in progress for the OpenPOWER firmware and the Linux Kernel layers. About Claudio Siqueira de Carvalho Claudio Carvalho is a brazilian Linux enthusiastic with over 15 years of experience in the Linux field. He started his career as a package builder during his Master's degree at the University of Campinas, building packages for Linux distributions based on Arch and Debian. In 2011, he joined the IBM Linux Technology Center, where he has worked on several Linux security projects since then. He worked on linux security certifications (HIPAA, Common Criteria and FIPS 140-2); OpenCryptoKi, which is an open source implementation of the CryptoKi API defined by the PKCS #11; and also OpenSSL plugins. Currently, he is an OpenPOWER firmware developer and he also leads the Secure and Trusted Boot development team in the IBM Linux Technology Center.

Leveraging Blockchain for Identity and Authentication in IoT is good for Security Since the beginning of the internet, attempts have been made to solve the problem of privacy and security. Every effort has had challenges of inconvenience, cost and insecurity. How do we prove our identity? Blockchain technology and its mutual distributed ledgers (MDL) cannot be altered and allow people and companies to record, validate and track transactions throughout a network of decentralized computer systems. These MDLs are databases with a time stamped audit trail. By leveraging this technology, an app on our device will hash our identifying information and insert this into the public Blockchain. Anytime you need to authenticate to another service or user, you share the information which is then sent through the algorithm and checked against the Blockchain. Once authenticated, your information for identification is not needed again. If the hashed information is decentralized and provides interoperability. Personal information never leaves the device and is not stored on a centralized server. Taking the personal data, hashing it and then discarding everything but the hashes of our personal data allows the network to accept the information in the same manner as our ID cards. These Blockchains open the door to innovation and enables more interoperability connecting various distributed services. There can be 2 unique MDLs; one to hold the encrypted documents and a separate ledger that will hold encryption key access which are folders encompassing our identity, health or other qualifying records. Driver’s license bureaus can provide us a digitally signed copy of our driver’s license that we control. We then offer controlled usage to entities that need to inspect the documents, the information recorded on the MDL. This use of immutable ledger can become the accepted modality of the future. Speakers Donald Malloy Chairman, OATH Donald Malloy is the Chairman of OATH, The Initiative for Open Authentication. OATH is an industry alliance that has opened the authentication market from proprietary systems to an open source standard based architecture promoting ubiquitous strong authentication. - Managed by the official OWASP Media Project https://www.owasp.org/index.php/OWASP_Media_Project

However, Ethereum Certification Training is best suited for the below mentioned profiles:- Software Developers Full Stack Developers Why should you go for this ethereum developer's course? Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middleman or counterparty risk. Using Ethereum, you can create a contract that will hold a contributor's money until any given date or goal is reached. Depending on the outcome, the funds will either be released to the project owners or safely returned to the contributors. All of this is possible without requiring a centralized arbitrator, clearinghouse or having to trust anyone. You can even use the token you created earlier to keep track of the distribution of rewards.

Direct from the mind of the guy who bought you the "I will kill you" presentation at DEF CON 23, is another mind bending, entertaining talk. This time it’s bigger and badder than before. Are you sick and tired of your government? Can’t wait another 4 years for an election? Or do you want to be like the CIA and overthrow a government overseas for profit or fun? If you answered yes to one or more of these questions than this talk is for you! Why not create your own cyber mercenary unit and invoke a regime change to get the government you want installed? After all, if you want the job done right, sometimes you have to do it yourself. Find out how over the last 60 years, governments and resource companies have been directly involved in architecting regime changes around world using clandestine mercenaries to ensure deniability. This has been achieved by destabilizing the ruling government, providing military equipment, assassinations, financing, training rebel groups and using government agencies like the CIA, Mossad and MI-5 or using foreign private mercenaries such as Executive Order and Sandline. Working with Simon Mann an elite ex SAS soldier turned coup architect who overthrew governments in Africa, Chris Rock will show you how mercenary coup tactics directly applied to digital mercenaries to cause regime changes as the next generation of "Cyber Dogs of War". Chris will walk you through a cyber regime change from start to finish on a real country and show you how to architect a coup achieving the same result as a traditional mercenary operation without any blood spilt. This will include taking ownership of all facets of government including finance, telecommunications, transportation, commercial companies and critical infrastructure such a power, water and oil. You will learn: • Traditional military mercenary coup tactics used by the infamous 32 Battalion in Africa, Executive Order and Sandline that can be directly applied to a cyber mercenary regime change. • How to architect a cyber coup using advisor’s, hackers and the general populace, using misinformation, professional agitators, false information and financing. • How to gather intelligence to analyze a government’s systemic weaknesses on financial, societal values and political climates that is leader or country specific to structure your attack. • How to identify and prioritize government resources, infrastructure and commercial companies and how to use these compromised assets to stage the coup. • Combine physical and digital techniques and have the best of both worlds to own a countries infrastructure. • Hot to manipulate the media using propaganda targeting journalists flawed multiple "source" rules for a story. • The Grand finale of a cyber regime change on a real country from beginning to end using the above techniques with operational footage. Come to this talk and find out how you too can be your own dictator, benevolent or merciless that part is up to you. Chris Rock presented "I will kill you" at DEF CON 23 has been active in the security industry for the last 20 years and is the founder and CEO of Kustodian, a specialized security company that specializes in Security Operations Centres, Penetration testing and independent research. Kustodian is an Australian, Middle East and Hong Kong registered company that has been operational for over 10 years. Chris has also spent 12 years in the banking sector and provides security services around the world for small, medium and large companies. Chris Rock also created SIEMonster, an open source, scalable, free Security Incident and Event Management (SIEM) as a commercial alternative to Splunk, ArcSight and AlienVault. SIEMonster can be run on Amazon AWS or Virtual machines and details can be found on www.siemonster.com Twitter: @_kustodian_
