Attacks on Bresson-Chevassut-Essiari-Pointcheval's Group Key Agreement Scheme for Low-Power Mobile Devices

Junghyun Nam, Seungjoo Kim, and Dongho Won

Abstract

In this paper, 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.
