Securing network traffic has always been a must requirement for any network application that employs insecure communication channel.The reason is to provide protection for the transmitted data over the network against unauthorized disclosure and modification of the messages between communicating parties.A Key exchange protocol is the cryptographic primitive that can establish a secure communication.The first Key exchange protocol was introduced by Diffie-Hellman.The purpose of the Diffie-Hellman protocol is to enable two parties to securely exchange a session key which can then be used for next symmetric encryption of messages.However, Diffie-Hellman itself does not authenticate the communicating entities.In this paper, we study on Diffie-Hellman Key exchange protocol.Subsequently describe authenticated key exchange protocol and One-pass key exchange protocol, which are the variants of Diffie-Hellman protocol.
