Abstract
Bresson et al. have recently proposed an efficient group key agreement scheme well suited for a wireless network environment. Although it is claimed that the proposed scheme is provably secure under certain intractability assumptions, we show in this paper that this claim is unfounded, breaking the allegedly secure scheme in various ways.
Keywords
Group key agreement; key authentication; forward secrecy; known key security; collusion attack; interleaving attack;
