Information trouvée : 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 (coinvented
by Michael Schroeder) security protocol forms the basis of the Kerberos authentication
and key exchange system. He also codesigned the TEA and XTEA encryption algorithms.
He joined Cambridge's Computer Laboratory in 1962, became head of the lab in 1980
and remained there until his retirement in 1995. Needham set up Microsoft's UK-based
Research Labs in 1996.
