Compared with protocols under the CRS model, the group key exchange protocol can greatly reduce the risk of putting all trusts in one place. The protocol is proved to be AKE secure and resistant to the attacks of adaptive adversaries and malicious insiders. %K Secure communication %K Universally composable %K Witness indistinguishable %K Proof of knowledge %K Common Reference String (CRS) model
