The pervasive usage of the Internet has made secure group communications a significant issue. Conference key agreement protocols provide secure group communications against some attacks with lower computational cost in the Internet. However, forward secrecy is a challenging issue in the existing protocols, where it is preserved either the long-term key of a participant is compromised. In this study, we propose an improved conference key agreement protocol with forward secrecy. Besides providing forward secrecy, the proposed protocol preserves the same security level with existing ones.
