Abstract

Based on Buchmann-Williams key exchange protocol, a Buchmann-Williams Authenticated Key Agreement (BWAKA) protocol with pre-shared password is proposed. Its security relies on the Discrete Logarithm Problem over class groups of number fields. It provides identity authentication, perfect forward secrecy and key validation.

Keywords:

Diffie-Hellman, reduced ideals, simple authenticated key agreement,
