A pioneer of the information security community, Dr. Whitfield Diffie, will be giving the keynote at the Tuesday evening reception. Dr. Diffie is best known for discovering the concept of public key cryptography. The Diffie-Hellman key was invented in 1976 during a collaboration between Whitfield Diffie and Martin Hellman and was the first practical method for establishing a shared secret over an unprotected communications channel. Whitfield will provide a historical context to cyber security and the challenges in the future. Having heard Whitfield before, it will be a very interesting and enjoyable evening.
