He has also served as a visiting scholar (2009–2010) and affiliate (2010–2012) at the Freeman Spogli Institute's Center for International Security and Cooperation at Stanford University, where he is currently a consulting scholar. Īfter a long career at Sun Microsystems, where he became a Sun Fellow, Diffie served for two and a half years as Vice President for Information Security and Cryptography at the Internet Corporation for Assigned Names and Numbers (2010–2012). The article stimulated the almost immediate public development of a new class of encryption algorithms, the asymmetric key algorithms. Their technique became known as Diffie–Hellman key exchange. Diffie and Hellman's 1976 paper New Directions in Cryptography introduced a radically new method of distributing cryptographic keys, that helped solve key distribution-a fundamental problem in cryptography. edu /people /whitfield _diffieīailey Whitfield 'Whit' Diffie (born June 5, 1944), ForMemRS, is an American cryptographer and one of the pioneers of public-key cryptography along with Martin Hellman and Ralph Merkle.
