Prevention of Man-In-The-Middle Attack in Diffie-Hellman Key Exchange under Specific Environment
Yang Fu-xiang · Information Security and Communications Privacy · 2009
Diffie-Hellman key exchange algorithm is an algorithm that can ensure the security of key negotiation in a channel where eavesdropping may exist, but can not be immune to the so called man-in-the-middle attack. However, that kind of attack can be prevented by using the method of key authentication. In this paper, both the theoretical proofs practical application examples of this method are given. A new method for generating random number is describes finally.
