%X In order to manage the dynamic multicast efficiently,this paper proposed some management schemes for dynamic multicast group.And analyzed those schemes which based on bi-layered key management and security hash functions, and then presented a new management scheme which was called GC-RH(group center-random GC-random and hash) and related key-updating algorithm. Simulation results show that this scheme has strong points in the key storage, encryption, network traffic aspects over other ones,which fits those large-scale dynamic multicast environment.
