Symmetric Key and Public Key Encryption
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.

Support MinutePhysics on Patreon! http://www.patreon.com/minutephysics This video explains Shor’s Algorithm, a way to efficiently factor large pseudoprime integers into their prime factors using a quantum computer. The quantum computation relies on the number-theoretic analysis of the factoring problem via modular arithmetic mod N (where N is the number to be factored), and finding the order or period of a random coprime number mod N. The exponential speedup comes in part from the use of the quantum fast fourier transform which achieves interference among frequencies that are not related to the period (period-finding is the goal of the QFT FFT).

MD5 Hash Tutorial - What the MD5 hash means and how to use it to verify file integrity.
Please like / share / subscribe if you like my MD5 hash tutorial! Here I explain how you use the MD5 hash of a file to verify its integrity in a simple MD5 hash tutorial. We use a windows based utility, md5sum.exe (http://www.etree.org/md5com.html) to check the integrity of a picture before and after we make an almost imperceptible change. Of course, we need not have used a picture, we could use any digital file to demonstrate the power of the MD5 hash for file integrity checking. As you will see in the video, using MD5 hashing, you can guarantee / verify the integrity of a Word document, a picture, a sound or video file or a software application. Reasons an integrity check might fail could be through file corruption on disk, communications corruption while downloading or even unauthorised tampering. I hope you enjoy the video, more coming soon.

What are certificates?
Certificates are used to prove identity and used for creating secure communication. Check out http://itfreetraining.com for more of our always free training videos. This video looks at how a certificate works, what is a certificate and how they are used for identification and secure communication. Download the PDF handout http://itfreetraining.com/Handouts/Certificates/WhatAreCertificates.pdf What is a certificate? A certificate is an electronic document that contains data fields. When compared to a traditional paper certificate there are some similarities between an electronic certificate and a physical certificate. Digital certificates like a physical certificate are issued by an authority. For example, a university may issue a certificate to a student to show that they have completed the necessary work in order to graduate. The next question is, would you trust a physically certificate? Digital certificates work the same way. They are issued from an authority and the question becomes would you trust the authority that issued the certificate? Electronic certificates also contain other fields like who or what the certificate was issued to, how long it is valid, the public key and the digital signature. If a digital certificate is presented to a user or computer, the user or computer is able to check the certificate to ensure the person using it should be using it. Also the certificate contains a digital signature which allows the certificate to be checked to make sure it has not been modified. Digital Signature A digital signature provides a method for a certificate to be checked to ensure it has not been modified. In order to do this, a hash value is created for the certificate. To generate a hash value the certificate is put through a function to create a single value. Hash functions are designed so different certificates will not produce the same value, however the hash value cannot be used to generate the original certificate. The same principal applies to a person's fingerprints. They can be used to identify a person, however using a finger print you could not work out the features of a person like what color hair they have. When a certificate is created, the hash value for that certificate is also created. Using a function involving the private key, a digital signature is created and added to the certificate. Digital Signature Example When a certificate is used, in order to check the certificate has not been changed, the following is done: The computer generates the hash value for the certificate. Next, the digital signature is put through a function using the public key which should result in the same hash value. If both values match, the certificate has not been modified. This prevents a 3rd party taking a certificate, changing the values in the certificate and using the certificate. Trust Model Certificates work off a trust model. An example of a trust model in computers is that a computer may have a sticker on it indicating which operating systems it will run. The consumer, seeing this sticker, must trust that the manufacture would not put this sticker on the laptop unless it will run that operating system. The customer must also trust the creator of that operating system would not allow a computer manufacturer to put a sticker on a computer that would not run that operating system. Certificate Trust Model Certificates are generally deployed in a hierarchy. At the top is the root certificate authority. This can be an internal Certificate Authority or an external authority like VeriSign. When an authority like VeriSign issues a certificate, they will perform a number of checks on the individual purchasing the certificate to ensure that they are a valid business. When a certificate is used it can be checked to see which authority issued that certificate. In order for the certificate to be used, the computer must trust the authority that it was issued from. Authorities like VeriSign are trusted by default on most operating systems. Certificate Error If a certificate is presented to the computer and it is not trusted, the computer will generate an error asking if the users want to trust the certificate. It is up to the user to decide if they believe the certificate is valid. Certificate Hierarchy Certificates use a hierarchy. At the top is the root CA, below these are subordinate CA's. Any level can issue certificates to subordinate CA's or direct to users, computers or devices. If the user, computer or device trusts the root CA, then any certificate that is issued by any CA in the hierarchy will automatically be trusted and thus used by the client.

symmetric key cryptography
https://8gwifi.org/CipherFunctions.jsp Reference book: http://leanpub.com/crypto Cryptographic Algorithms generally fall into one of two different categories, or are a combination of both. Symmetric Fast Only provide confidentiality Examples: DES, AES, Blowfish, RC4, RC5 Asymmetric Large mathematical operations make it slower than symmetric algorithms No need for out of band key distribution (public keys are public!) Scales better since only a single key pair needed per individual Can provide authentication and nonrepudiation Examples: RSA, El Gamal, ECC, Diffie-Hellman problem with symmetric key cryptography DES (Data Encryption Standard) 64 bit key that is effectively 56 bits in strength Actual algorithm is called DEA (Data Encryption Algorithm) DES Modes Electronic Code Book Cipher Block Chaining (most commonly used for general purpose encryption) Cipher Feedback Output Feedback Counter Mode (used in IPSec) 3DES 112-bit effective key length Uses either 2 or 3 different smaller keys in one of several modes Modes EEE2/3 EDE2/3 AES NIST replaced DES in 1997 with this Uses the Rijndael algorithm Supports key/block sizes of 128, 192, and 256 bits Uses 10/12/14 rounds as block size increases IDEA (International Data Encryption Algorithm) Operates on 64 bit blocks in 8 rounds with 128 bit key Considered stronger than DES and is used in PGP Blowfish 64 bit block cipher with up to 448 bit key and 16 rounds Designed by Bruce Schneier RC4 Stream cipher with variable key size created by Ron Rivest RC5 Another Rivest cipher Block cipher with 32/64/128 bit blocks and keys up to 2048 bits RC6 Beefier version of RC5 submitted as AES candidate CAST 64 bit block cipher with keys between 40-128 bits with 12-16 rounds depending on key length CAST-256 used 128-bit blocks and keys from 128-256 bits using 48 rounds SAFER (Secure and Fast Encryption Routine) Set of patent-free algorithms in 64 and 128 bit block variants Variation used in Bluetooth Twofish Adapted version of Blowfish with 128 bit blocks, 128-256 bit keys and 16 rounds AES Finalist Kryptografie mit symmetrischem Schlüssel symmetric key cryptography symmetric key cryptography tutorial symmetric key cryptography example symmetric key cryptography vs asymmetric key cryptography symmetric and asymmetric key cryptography symmetric key cryptography Kryptografie mit symmetrischem Schlüssel Kryptographie mit symmetrischem Schlüssel Kryptographie mit symmetrischem Schlüssel Kryptografie mit symmetrischem Schlüssel und asymmetrische Schlüsselkryptographie symmetrische und asymmetrische Schlüsselkryptographie Kryptografie mit symmetrischem Schlüssel

FREE File Encryption and Decryption Software in JAVA
You can download the source code and the executable from here: https://github.com/arlenebatada/File-Encryption-and-Decryption-Application-in-JAVA Do you wish to convert your music to a form in which others cannot listen it? Do you wish to convert your movies to a form in which others cannot watch them? Do you wish to convert your documents to a form in which others cannot read them? Do you wish to convert your executable files to a form in which others cannot execute them? If your answer to any of the above questions is "YES" then this software is definitely for you. With this software you can perform ENCRYPTION and encrypt your video files, audio files, text files, executable files, pdf, or any other file of your choice. This way, without your password, files such as movies, music, pdf, documents, images, etc. won't open. Executable files will no longer be in a state to be executed. Would you like to have your encrypted files back in the form they used to be? Don't worry. It is also other way around. With the password you had used for encryption you can perform DECRYPTION and convert your files back to their original form. Moreover, the application does NOT store your passwords. Instead it uses SHA-512 hashing algorithm to verify the password.

The Tiger & a Whirlpool-Attack
Abstract. In this paper, we develop a new attack on Damg°ard-Merkle hash functions, called the herding attack, in which an attacker who can find many collisions on the hash function by brute force can first provide the hash of a message, and later herd any given starting part of a message to that hash value by the choice of an appropriate suffix. We focus on a property which hash functions should haveChosen Target Forced Prefix (CTFP) preimage resistanceand show the distinction between Damg°ard-Merkle construction hashes and random oracles with respect to this property. We describe a number of ways that violation of this property can be used in arguably practical attacks on real-world applications of hash functions. An important lesson from these results is that hash functions susceptible to collision-finding attacks, especially brute-force collision-finding attacks, cannot in general be used to prove knowledge of a secret value. Introduction Cryptographic hash functions are usually assumed to have three properties: Collision resistance, preimage resistance, and second preimage resistance. And yet many additional properties, related to the above in unclear ways, are also required of hash function in practical applications. For example, hash functions are sometimes used in commitment schemes, to prove prior knowledge of some information, priority on an invention, etc. When the information takes on more than a small number of possible values, there does not appear to be an obvious way to extend a collision finding attack to break the commitment scheme; therefore, collision resistance does not seem to be necessary to use the hash function in this way. This appears fortunate in light of the many recent attacks on collision resistance of existing hash functions[2, 3, 13, 19, 2124] and the widespread use of hash functions short enough to fall to brute-force collision attacks 20. We show that the natural intuition above is incorrect. Namely, we uncover (what we believe to be) subtle ways of exploiting the iterative property of Damg°ard-Merkle[6, 16] hash functions to extend certain classes of collision-finding attacks against the compression function to attack commitment schemes and other uses of hash function that do not initially appear to be related to collision resistance. http://www.cs.washington.edu/homes/yoshi/papers/EC06/herding.pdf http://video.google.com/videoplay?docid=-6086749167583048867 http://downloads.bistum-augsburg.de/108313636519180.pdf

It certainly isn’t inaccurate to say that blockchain technology was developed in an effort to circumvent the currenct financial system and all of those annoying middlemen. The goal was always to bring decentralization to all and to finally empower individuals to take control of their wealth, to be their own bank. But now, looking at the largest and arguably the most successfully crypto in regards to adoption, the one we all know as Bitcoin, we’re beginning to see this ideology taking the backseat. Mainly, there is no doubt a type of centralization occurring with the mining pools of bitcoin. There are now a handful of companies who can control the transactions of Bitcoin. The only reason there was room for this to happen is thanks to the inclusion of transaction fees as a way to motivate miners to participate in the network. Despite Satoshi’s best efforts to invent a system that could undermine the greedy financial system as we know it today, because money is still being used as a motivator in this new system, and us still being humans that are running it, we are still vulnerable of our human condition, in this case, that is to be greedy. We are always looking for fast transactions, low or no fees and complete decentralization. Many cryptos have these perks right now, but the issue that hangs over everyone’s head is that of scalability. This is where IOTA can be a game changer, and here’s why. IOTA uses a type of DAG that they are calling “Tangle.” In their system, if you want to participate in their network, if you want to make transactions on their network, you need to help. For every transaction you’d like to submit on IOTAs Tangle, you will have to process two transactions from other users. This shifts the motivating factor from extrinsic (that is only processing transactions for the sake of getting paid) to intrinsic (you help to secure the network so that you may also take part in it.) This also means that the more users of this network, the faster the transactions will be confirmed. IOTA has the potential to be completely decentralized, but for now, in its beginning stages, the network uses what you could call a bottleneck that they refer to as the “Coordinator.” So for now, it hasn’t yet reached it’s ideal status of being completely decentralized. That being said, there are some security concerns that have been voiced. One of the points has to do with a flaw in the custom hash function called Curl. Basically, instead of taking tried and true cryptographic primitives to build their system, the IOTA team decided to write their own hash function called Curl. Basically, this can open the door for vulnerabilities concerning the validation of transactions. If you’d like to learn more about this concern and how the IOTA team has since addressed the issue you can always take a look at their blog.

Ⓑ Blockchain Overview: Bitcoin, Cryptocurrency, Cryptography, & Satoshi Nakamoto
In this video I go over a very extensive overview of all things Blockchain, from its initial public appearance through the creation of Bitcoin cryptocurrency to the endless applications. I also cover some of the mathematics that make all of this possible, which is in advancements in Cryptography, or the study of securing communications in the midst of third parties. The first implementation of a decentralized peer-to-peer distributed ledger that solves what it is known as the Byzantine Generals’ Problem as well as the infamous digital Double Spending problem was in 2009 by an anonymous person or group known as Satoshi Nakamoto, and in the form of a digital currency called Bitcoin. The implementation of Bitcoin, a year after its 2008 whitepaper illustrating the concept, utilized the first decentralized Blockchain algorithm. In just under 10 years, the value of Bitcoin has skyrocketed to $7000+ USD per coin as of the making of this video. But the underlying technology, a distrusted Blockchain has some truly game-changing capabilities. Blockchain technology is made possible by the mathematics of Cryptography, namely the development of the Public-key or Asymmetric key encryption concept. This is a seemingly simple concept but its implications are monumental. Through the use of mathematical “one-way functions” that are easy to solve in one direction and extremely difficult to solve in the other, it is possible to share encrypted messages even if the third party gained full access to all the communications channels! Extending this to the blockchain, blocks of data with cryptographically secured by a timestamp can be chained together to form one very long secure chain. This chain of blocks, known as the blockchain, serves as the single agreed upon history of by all computers and thus people using the blockchain; all this without a central authority! Other concepts I cover in this very long video is in Cryptocurrency Wallets, hard vs soft forks, the Bitcoin whitepaper, my favorite blockchain technology Steemit, and some of the things to know before creating your own cryptocurrency or heavily investing in a relatively unknown company. But as with all of my recent videos, I need to include a full disclosure into my views on Blockchain and all technology for that matter, and which is that I view most advancements in technology as a result of the powers-that-shouldn’t-be trickling down tech to us in a gradual manner. It is done this way so that there isn’t too much of a disruption to the current establishment and to better steer the world into more centralization. To learn more about my reasoning here, make sure to follow my ongoing video series on 9/11 and free energy: https://mes.fm/911truth-playlist and https://mes.fm/freeenergy-playlist. Blockchain technology, although has the ability to decrease centralization of control, it ironically can do just the opposite if its access is restricted by the governmental corporate monopolies such as the CIA, Apple, Google, Amazon, and Facebook. But whether Blockchain is a trickle-down technology or a truly great innovation by Satoshi Nakamoto, it nonetheless is a very special technology which if we smarten up, and avoid the consumerism propaganda pushed at us at all levels of society, we may in fact be able to use it to ensure a truly self-sufficient lifestyle free of government tyranny… PDF Notes:: https://1drv.ms/b/s!As32ynv0LoaIh4dVs3zFksqAN2pZnQ Steemit Notes: https://steemit.com/blockchain/@mes/blockchain-overview-bitcoin-cryptocurrency-cryptography-and-satoshi-nakamoto Related Videos: Steemit Overview: Social Media, Steem Blockchain #GetOnSteem: https://youtu.be/1RBzUDRScyQ Steemit Tutorial: Steem (STEEM), Steem Power (SP), and Steem Dollars (SMD): https://youtu.be/F5f1duDJG9Q ✈️#911Truth Part 6: Controlled Opposition: 'Mini Nukes', 'Building 7', AE911Truth Hoax: https://youtu.be/aDWgsVSo4Oc ⚡#FreeEnergy Part 2: Nuclear Physics Overview + Cold Fusion: https://youtu.be/wMB5xmONX58 . ------------------------------------------------------ SUBSCRIBE via EMAIL: https://mes.fm/subscribe DONATE! ʕ •ᴥ•ʔ https://mes.fm/donate Like, Subscribe, Favorite, and Comment Below!

Stanford Seminar - The Evolution of Public Key Cryptography
EE380: Computer Systems Colloquium Seminar The Evolution of Public Key Cryptography Speaker: Martin Hellman, Stanford EE (Emeritus) While public key cryptography is seen as revolutionary, after this talk you might wonder why it took Whit Diffie, Ralph Merkle and Hellman so long to discover it. This talk also highlights the contributions of some unsung (or "under-sung") heroes: Ralph Merkle, John Gill, Stephen Pohlig, Richard Schroeppel, Loren Kohnfelder, and researchers at GCHQ (Ellis, Cocks, and Williamson). Resources and Reading Materials M. E. Hellman, Cybersecurity, Nuclear Security, Alan Turing, and Illogical Logic (http://www-ee.stanford.edu/ %7Ehellman/publications/77.pdf), Communications of the ACM, Vol. 60, No. 12, pp. 52-59, December 2017. This is a written version of Martin Hellman's ACM Turing Lecture (https://www.youtube.com/watch?v=I132wSwAI3o) and was accompanied by a short (6 minute) video (https://vimeo.com/241030842). Other materials and hard to find references can be found on Martin Hellman's Stanford website, http://www-ee.stanford.edu/~hellman/ . About the Speaker: Martin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University and is affiliated with the university's Center for International Security and Cooperation (CISAC). His recent technical work has focused on bringing a risk informed framework to a potential failure of nuclear deterrence and then using that approach to find surprising ways to reduce the risk. His earlier work included co- inventing public key cryptography, the technology that underlies the secure portion of the Internet. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science. His most recent project is a book, jointly written with his wife of fifty years, "A New Map for Relationships: Creating True Love at Home & Peace on the Planet," that provides a "unified field theory" of peace by illuminating the connections between nuclear war, conventional war, interpersonal war, and war within our own psyches.
