WebThe Diffie-Hellman protocol is a scheme for exchanging information over a public channel. If two people (usually referred to in the cryptographic literature as Alice and Bob) wish to communicate securely, they need a way to exchange some information that will be known only to them. In practice, Alice and Bob are communicating remotely (e.g. over the … WebOften the exchange was done by courier. In 1976, Whitfield Diffie and Martin Hellman in their paper “new Directions in Cryptography” proposed a method of key exchange that did not require a secure channel but was secure against eavesdropping. The security of Diffie-Hellman key exchange is based on the discrete logarithm problem.
