GAC/GKM: a group access control architecture for secure multicast
Li-Xin, Zhang-Peng, Ye-Chengqing · 2005
In this paper, a group access control architecture for secure multicast is proposed. This architecture substantially reduces the infrastructure requirement by leveraging the existence of the group key management system. It also reduces the network and compute overhead by utilizing the group key as authenticator. Furthermore, it eliminates the propagation of sender access control list among on-tree routers. The simulation result shows that it is more efficient than Gothic.
