Professor Whitfield Diffie ForMemRS

Foreign Member

Elected:2017

Dr Whitfield Diffie is best known for discovering the concept of public key cryptography, which underlies the security of internet commerce and all modern secure communication systems. He is a Consulting Scholar in the Center for International Security and Cooperation at Stanford and a Visiting Professor at Royal Holloway College of the University of London.

After leaving Stanford University in the late 1970s, he became Manager of Secure Systems Research for Bell-Northern Research, the laboratory of the Canadian telephone system.  In 1991, he moved to Sun Microsystems, rising to be Vice-President, Sun Fellow, and Chief Security Officer until 2009.  Since leaving Sun, he has worked primarily as an advisor to innovative startups in the security field.  Diffie received the 2015 Turing Award and in 2017 was elected to the National Academy of Engineering.

Since 1993, much of Diffie's attention has been focused on public policy, in the areas of cryptography, security, and privacy. His position --- in opposition to limitations on the business and personal use of cryptography --- has been the subject of articles in the New York Times Magazine, Wired, and Discover and programs on CNN, the Discovery Channel, and Equinox TV.
