Group communication can benefit from Internet Protocol (IP) multicast protocol to achieve efficient exchange of messages. However, IP multicast does not provide any mechanisms for authentication. In literature, many solutions to solve this problem were presented. It has been shown that Wong and Lam protocol is the only protocol that can resist both packet(More)
The key distribution problem is considered one of the most important issues for providing secure multicast communication. Logical Key Hierarchy (LKH) protocols are considered one of the best solutions proposed for solving the scalability of multicast key distribution protocols. The use of LKH protocols reduces the computation complexity cost from O(n),(More)
