Multiserver Approach for Large-Scale Secure Multicast in Wireless Environments

This paper proposes a multiserver architecture for group key management to minimize the overall system bandwidth. The proposed system utilizes the dynamic split and merge with a low overhead where a physical server adaptively splits and merges its traffic into multiple groups, each served by a logical server so as to minimize its total bandwidth. The performance of this proposed approach is compared with that of the single-server case. The results show that multiserver architecture scales well when compared with the single-server approach
