Roger Needham was a British computer scientist and a leading figure in computer security research. With Michael Schroeder he co-developed the Needham-Schroeder family of authentication protocols in the early 1980s, which shaped much of the later theory and practice of secure network authentication, and he served for many years as head of the University of Cambridge Computer Laboratory before later leading Microsoft Research in Cambridge.

What did Roger Needham contribute to security besides the Needham-Schroeder protocol?
He co-designed the TEA and XTEA encryption algorithms and pioneered protecting passwords with a one-way hash function.
Needham also co-designed the TEA and XTEA encryption algorithms, and he pioneered the technique of protecting passwords with a one-way hash function. Storing a hash instead of the password itself means that a stolen password file does not directly reveal the passwords it protects.
