Roger Needham

Roger Needham in 1999
Roger Michael Needham (February 9, 1935 - February 28, 2003) was a British computer scientist.

Needham joined the University of Cambridge in 1956. His PhD thesis was on applications of digital computers to problems of classification. He became a highly respected scholar and worked on a variety of key computing projects in security, operating systems, computer architecture (capability systems[?]) and local area networks.

Among his theoretical contributions is the development of the Burrows-Abadi-Needham logic for authentication, generally known as the BAN logic. His Needham-Schroeder[?] security protocol forms the basis of the Kerberos authentication and key exchange[?] system.

He joined Cambridge's Computer Laboratory[?] in 1962, became head of the lab in 1980 and remained there until his retirement in 1995. Dr. Needham set up Microsoft's UK-based Research Labs in 1996.

In 2001 he received a CBE for his contribution to computing. He was married to Karen Sparck Jones[?].

He died of cancer in February 2003 at his home in Coton, England.
