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.

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.

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.

What is digital signature?
A digital signature is equivalent to a handwritten signature in paper, and a digital signature serves three basic purposes. Digital signature is commonly used for software distribution, financial transactions and other cases where it is important to detect forgery. Digital signatures are very popular with e-mail users. In this video, I will talk about the digital, uses, and the whole process of creating and sending digitally signed document over the Internet. Keep in mind, digital signature is not about encrypting document, just like paper-based signature.

Key Exchange
This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop. You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site. There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

Will Quantum Computers break encryption?
How do you secure messages over the internet? How do quantum computers break it? How do you fix it? Why don't you watch the video to find out? Why does this description have so many questions? Why are you still reading? What is the meaning of life? Facebook: https://www.facebook.com/frameofessence Twitter: https://twitter.com/frameofessence YouTube: https://www.youtube.com/user/frameofessence CLARIFICATIONS: You don't actually need a quantum computer to do quantum-safe encryption. As briefly mentioned at 7:04 , there are encryption schemes that can be run on regular computers that can't be broken by quantum computers. CORRECTIONS: [2:18] Technically, you can use any key to encrypt or decrypt whatever you want. But there's a specific way to use them that's useful, which is what's shown in the video. [5:36] In RSA, depending on exactly what you mean by "private key", neither key is actually derivable from the other. When they are created, they are generated together from a common base (not just the public key from the private key). But typically, the file that stores the "private key" actually contains a bit more information than just the private key. For example, in PKCS #1 RSA private key format ( https://tools.ietf.org/html/rfc3447#appendix-A.1.2 ), the file technically contains the entire public key too. So in short, you technically can't get the public key from the private key or vice versa, but the file that contains the private key can hold more than just the private key alone, making it possible to retrieve the public key from it.

Attacking RSA with lattice reduction techniques (LLL)
This video is an explanation of Coppersmith's attack on RSA, which was later simplified by Howgrave-Graham, and the later attack by Boneh and Durfee, simplified as well by Herrmann and May. Both use LLL, the lattice reduction algorithm of Lenstra Lenstra Lovasz. You can find the code on github here: https://github.com/mimoo/RSA-and-LLL-attacks You can find a survey here: https://github.com/mimoo/RSA-and-LLL-attacks/raw/master/survey_final.pdf You can find my blog here: http://www.cryptologie.net
