Abstract

In order to hold secure electronic conference in communication networks via insecure channels, a conference key distribution system should be constructed. The conference key distribution system is used for distributing a conference key shared among the participants of the conference and hence secure communications are achieved. In this paper, by using the sealed lock proposed in [1], we propose an identity-based conference key distribution scheme with user anonymity. We also show that, our scheme not only withstands passive attack, impersonation attack, and conspiracy attack, but also provides forward security of the chairman. These properties make it quite effective and practical.
