Constant Round Dynamic Group Key Agreement

Constant Round Dynamic Group Key Agreement

Download eprint.iacr.org

We present a fully symmetric constant round authenticated group key agreement protocol in dynamic scenario. Our proposed scheme achieves forward secrecy and is provably secure under DDH assumption in the security model of Bresson et al. providing, we feel, better security guarantee than previously published results. The protocol is eﬃcient in terms of both communication and computation power.
