Roger Michael Needham (9 February 1935 – 1 March 2003)^[3] was a British computer scientist.^[4][5][6]

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.^[7] 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.^[7] 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.^[1][8]

Among Needham's 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.^[9][10]

In 1962, he joined the University of Cambridge's Computer Laboratory, then called the Mathematical Laboratory, serving as the Head of the Laboratory from 1980 until 1995. He was made a professor in 1981 and remained with the laboratory until his retirement in 1998. Between 1996 and 1998, Needham served as the pro-vice chancellor at the University of Cambridge.^[11] 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 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.^[12]

Needham was elected a Fellow of the Royal Society (FRS) in 1985 and a Fellow of the Royal Academy of Engineering (FREng) in 1993. He was appointed Commander of the Order of the British Empire (CBE) for his contributions to computing in 2001. Needham held honorary doctorate degrees from the University of Twente, Loughborough University,^[13] and the University of Kent.

Needham has several awards named after him in his honour. The British Computer Society established an annual Roger Needham Award in 2004.^[14]

The European Conference on Computer Systems (EuroSys)^[15] established the annual Roger Needham PhD Award.^[16] It awards €2,000 to a PhD student from a European university whose thesis is regarded to be an exceptional, innovative contribution to knowledge in the computer systems area.
