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 (CKDS) 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 secret sharing scheme based on the MDS code and the Diffie-Hellman key exchange scheme as the basic component, we propose an efficient and anonymous conference-key distribution scheme that supports conference membership changes dynamically. We also show that, based on the Diffie-Hellman (DH) and the one-way assumption, the proposed CKDS is secure against impersonation and conspiracy attacks, and the unattended ones reveal no useful knowledge about the conference key. In addition, the proposed CKDS allows for user anonymity.
