He attended Doncaster Grammar School for Boys in Doncaster (then in the West Riding).
Needham began his undergraduate studies at the University of Cambridge in 1953, graduating with a B.A. in 1956 in mathematics and philosophy. His Ph.D. 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.
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 with 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, then...
