Secure Key Exchange Against Man-in-the-Middle Attack: Modified Diffie-Hellman Protocol

One of the most famous key exchange protocols is Diffie-Hellman Protocol (DHP) which a widely used technique on systems around world depend. This protocol simple and uncomplicated, its robustness based Discrete Logarithm Problem (DLP). Despite this, he considered weak against man-in-the-middle attack. article presents completely different version DHP protocol. The proposed two verification stages. In first step, we check if pseudo-random value α that Alice sends to Bob has been manipulated! second make sure random β not manipulated. attacker Eve can impersonate neither nor Bob, manipulate their exchanged values, or discover secret encryption key.
