Design and Analysis of Diffie-Hellman-Based Key Exchange Using One-time ID by SVO Logic

Authenticated key exchange protocols have been developed to establish secure channel on the Internet. In this paper, we consider following attacks against an authenticated key exchange using shared secret: eavesdropping, DoS attack, replay attack, and impersonation. Besides prevention from all these attacks, efficiency is also important. In this paper, we propose a three-party authenticated key exchange protocol based on Diffie-Hellman key exchange with one-time ID, which is a user's extraordinary identity used only once K.
