Abstract: The secure distribution of the key is an important process of keeping the security of communication by using cryptographic technology. This paper introduces a protocol integrating Diffie-Hellman protocol into the digital signature standard, points out its weakness in perfect forward secrecy, proposes a new key exchange protocol and analyses its security and efficiency briefly.
