Abstract

A conference key distribution scheme based on the theory of quadratic residues is proposed in this article. In this scheme, conference key is distributed in a broadcast way and no one can impersonate the chairman to distribute the conference key. It can resist the replaying attack by using the time stamp T and authenticate the chairman. The amount of computation is small.
