A design of Diffie-Hellman based key exchange using one-time id in pre-shared key model

To exchange an important information through the Internet, an authenticated key exchange is required. In this paper, we consider the following attacks as the problems of an authenticated key exchange using shared secret: eavesdropping on identity, DoS attack, replay attack, and impersonation. Besides prevention from all these attacks, efficient key exchange should be realized. In this paper, we propose an authenticated key exchange system based on Diffie-Hellman key exchange with one-time ID, which can be used only once.
