Clifford Cocks Scientist
Clifford Christopher Cocks, CB, (born 28 December 1950) is a British mathematician and cryptographer at Government Communications Headquarters (GCHQ).He discovered the widely used encryption algorithm now commonly known as RSA, about three years before it was independently rediscovered by Rivest, Shamir, and Adleman at MIT. He has not been generally recognised for this achievement because his work was classified information, and therefore not released to the public at the time.
