Whitfield Diffie
From Wikipedia, the free encyclopedia
Bailey Whitfield 'Whit' Diffie (born June 5, 1944) is a US cryptographer and one of the pioneers of public-key cryptography.
He received a Bachelor of Science degree in mathematics from the Massachusetts Institute of Technology in 1965.
Diffie and Martin Hellman's paper New Directions in Cryptography was published in 1976. It introduced a radically new method of distributing cryptographic keys, that went far toward solving one of the fundamental problems of cryptography, key distribution. It has become known as Diffie-Hellman key exchange. The article also seems to have stimulated the almost immediate public development of a new class of encryption algorithms, the asymmetric key algorithms.[citation needed]
Diffie was Manager of Secure Systems Research for Northern Telecom, where he designed the key management architecture for the PDSO security system for X.25 networks.[citation needed]
In 1991 he joined Sun Microsystems Laboratories (in Menlo Park, California) as a Distinguished Engineer, working primarily on public policy aspects of cryptography. As of May 2007 Diffie remains with Sun, serving as its Chief Security Officer and as a Vice President. He is also a Sun Fellow.
In 1992 he was awarded a Doctorate in Technical Sciences (Honoris Causa) by the ETH Zurich. He is also a fellow of the Marconi Foundation and visiting fellow of the Isaac Newton Institute. He has received various awards from other organisations. In July 2008, he was also awarded a Degree of Doctor of Science (Honoris Causa) by Royal Holloway, University of London.[citation needed]
Diffie and Susan Landau's book Privacy on the Line was published in 1998 on the politics of wiretapping and encryption. An updated and expanded edition appeared in 2007.
Diffie is[when?] a visiting professor at the Information Security Group based at Royal Holloway, University of London.[1]

- Oral history interview with Martin Hellman Oral history interview 2004, Palo Alto, California. Charles Babbage Institute, University of Minnesota, Minneapolis. Hellman describes his invention of public key cryptography with collaborators Whitfield Diffie and Ralph Merkle at Stanford University in the mid-1970s. He also relates his subsequent work in cryptography with Steve Pohlig (the Pohlig-Hellman system) and others. Hellman addresses the National Security Agency’s (NSA) early efforts to contain and discourage academic work in the field, the Department of Commerce’s encryption export restrictions, and key escrow (the so-called Clipper chip). He also touches on the commercialization of cryptography with RSA Data Security and VeriSign.
