World-leaders in Cryptography: Whitfield Diffie (Online)

Whitfield Diffie is one of the greatest Computer Scientists ever. He - along with Marty Hellman - was one of the first to propose the usage of public key encryption and co-created the Diffie-Hellman (DH) key exchange method. Overall, the Diffie-Hellman method is still used in virtually every Web connection on the Internet, and has changed from using discrete log methods to elliptic curve methods. In 2015, Whitfield was also awarded the ACM Turing Prize - and which is the Nobel Prize equivalent in Computer Science.  In this on-line talk he meets with Edinburgh Napier University students, but the chat is open to anyone who would like to listen to Whitfield.
