A Secure Fault-Tolerant Conference-Key Agreement Protocol

An Enhanced Fault-Tolerant Conference Key Agreement Protocol

Establishing a secure communication of Internet conferences for participants is very important. Before starting the conference, all the participants establish a common conference key to encrypt/decrypt communicated messages. It enables participants to exchange the secure messages. Nevertheless, in the conference, if there are any malicious participants who may try to upset the key generation pr...

A Practical and Secure-Fault-Tolerant Conferenc-Key Agreement Protocol

When a group of people wants to communicate securely over an open network, they run a conference-key protocol to establish a common conference key K such that all their communications thereafter are encrypted with the key K. In this paper we propose a practical and provably secure fault-tolerant conference-key agreement protocol under the authenticated broadcast channel model. The adversary tha...

Recently, Tzeng proposed a provably secure and fault-tolerant conference-key agreement protocol. It requires only a constant number of rounds to establish a conference key among all honest participants. This article will show that Tzeng’s protocol does not offer forward secrecy. We say that a conference-key agreement protocol offers forward secrecy if the long-term secret key of any participant...
