Abstract

In this paper, we propose new password authenticated key exchange (PAKE) and protected password change (PPC) protocols without any symmetric or public-key cryptosystems. The security of the proposed protocols is based on the computational Diffie-Hellman assumption in the random oracle model. The proposed scheme can resist both forgery server and denial of service attacks.
