Secure key distribution is an important concern related to cryptography. The first published and most widely used key exchange algorithm is the Diffie-Hellman key exchange algorithm. The purpose of this algorithm is to enable two users to securely exchange a key that can be then used for subsequent encryption of messages. However, this algorithm suffers from man-in-the-middle attack, in which an opponent can perform eavesdropping and replay attacks, in which an opponent can replay the message later.
