Constant Round Dynamic Group Key Agreement
Ratna Dutta and Rana Barua
Abstract
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 {\em et al.} providing, we feel, better security guarantee than previously published results. The protocol is efficient in terms of both communication and computation power.
