Abstract

In this letter, we show that Bresson-Chevassut-Essiari-Pointcheval's group key agreement scheme does not meet the main security properties: Implicit key authentication, forward secrecy, and known key security. Also, we propose an improved version which fixes the security flaws found in the scheme.
