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.
