Roger Needham

Roger Michael Needham, CBE, FRS, FREng (9 February 1935 – 1 March 2003) was a British computer scientist.
Early life.
Roger Michael Needham was born in Birmingham, England, the only child of Phyllis Mary, "née" Baker ("c".1904–1976) and Leonard William Needham ("c".1905–1973), a university chemistry lecturer. He attended Doncaster Grammar School for Boys in Doncaster (then in the West Riding) going on to St John's College, Cambridge in 1953, and graduating with a BA in 1956 in mathematics and philosophy. His PhD thesis was on applications of digital computers to the automatic classification and retrieval of documents. He worked on a variety of key computing projects in security, operating systems, computer architecture (capability systems) and local area networks.
Career.
Among his theoretical contributions is the development of the Burrows-Abadi-Needham logic for authentication, generally known as the BAN logic. His Needham–Schroeder (co-invented with Michael Schroeder) security protocol forms the basis of the Kerberos authentication and key exchange system. He also co-designed the TEA and XTEA encryption algorithms. He pioneered the technique of protecting passwords using a one-way hash function.
In 1962 he joined the University of Cambridge's Computer Laboratory, then called the Mathematical Laboratory, becoming Head of Laboratory in 1980. He was made a professor in 1981 and remained with the laboratory until his retirement in 1995. In 1997 he set up Microsoft's UK-based Research Laboratory. He was a founding Fellow of University College, Cambridge, which became Wolfson College.
Needham was elected to the Royal Society in 1985, became a fellow of the Royal Academy of Engineering in 1993 and received a CBE for his contributions to computing in 2001. He also was a longtime and respected member of the International Association for Cryptologic Research, the IEEE Computer Society Technical Committee on Security and Privacy and the University Grants Committee. He was made a fellow of the Association for Computing Machinery in 1994.
Needham held honorary doctorate degrees from University of Twente, Loughborough University, and University of Kent.
Personal life.
Needham married fellow computer scientist Karen Spärck Jones in 1958. He died of cancer in March 2003 at his home in Willingham, Cambridgeshire.
Roger Needham Award.
The British Computer Society, in 2004, established an annual "Roger Needham Award" in his honour.
