The work proposes new conference key agreement protocols based on secret sharing. We discuss roles of the dealer and recovery algorithms in the trust structure which is the necessary condition for any key establishment protocol to achieve the intended security goals. Our conference key agreement protocol tackles the problem of entity authentication in conference key agreement protocols. The entity authentication is replaced by group authentication. To start a new conference all principals have to be active and broadcast their shares. If the conference goes ahead, all principals are sure that all principals are present and alive. The paper is concluded with a discussion about possible modifications and extensions of the protocol.
