Spies used to meet in the park to exchange code words, now things have moved on - Robert Miles explains the principle of Public/Private Key Cryptography note1: Yes, it should have been 'Obi Wan' not 'Obi One' :) note2: The string of 'garbage' text in the two examples should have been different to illustrate more clearly that there are two different systems in use. http://www.facebook.com/computerphile https://twitter.com/computer_phile This video was filmed and edited by Sean Riley.

Primes are the building blocks of math. But just how mysterious are they? Our study of prime numbers dates back to the ancient Greeks who first recognized that certain numbers can't be turned into rectangles, or that they can't be factored into any way. Over the years prime numbers have only become more and more sought. The Primes are the basis of internet banking and all encryption that allows the internet to exist depends on it. They are the building blocks of numbers themselves. This video covers what prime numbers are and how mathematicians throughout the globe have been instrumental in discovering a large variety of proofs about them, from the Fundamental Theorem of Arithmetic to Gauss' prime number theorem to touching on the Riemann Hypothesis.

For more detail on back substitution go to: http://bit.ly/1W5zJ2g Here is a link with help on relative primes: http://www.mathsisfun.com/definitions/relatively-prime.html This is (hopefully) a very simple example of how to calculate RSA public and private keys. Just to be clear: these values should not be used for any real encryption purposes.

Presenter Matthew Tosh looks at the complex subject of prime numbers, from the theories relating to them, to some of their uses, in an information-packed video for maths teachers. For centuries, mathematicians have been searching for both larger primes and ways of breaking numbers down into their prime factors. Here, we see how prime numbers are used in cryptography algorithms, to help keep our money safe. And starting with Euclid's fundamental theorem of arithmetic, this video explains the role prime numbers play in internet security. Licensed to CPD College Ltd.

From OSCON 2013: What do you need to know about prime numbers, Markov chains, graph theory, and the underpinnings of public key cryptography? Well, maybe more than you think! In this talk, we'll explore the branch of mathematics that deals with separate, countable things. Most of the math we learn in school deals with real-valued quantities like mass, length, and time. However, much of the work of the software developer deals with counting, combinations, numbers, graphs, and logical statements: the purview of discrete mathematics. Join us for this brief exploration of an often-overlooked but eminently practical area of mathematics. Don't miss an upload!

In symmetric key encryption the same key is used for both encryption and decryption. In contrast, in asymmetric key encryption a public key (known to everyone) is used for encryption and a private key (known only to the recipient) is used for decryption. Many asymmetric key encryption approaches are based on factoring as a trapdoor function, with the public key being the multiple of the two secret primes and the private key being the two secret primes. Asymmetric key encryption allows one party to encrypt a message to a second party they have never communicated with previously.
