| Abstract: | This paper introduces the design and implementation of group secure cooperative multi-session system based on multicast. Then the security problems of the system, such as information integrity, key management, and key distribution, are carefully discussed. A new secure group communication model and relative strategies based on multicast are proposed, and introduced into a cooperative multi-session system. The model and strategies presented in this paper are verified by the system. |
