【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.更多还原
