The efficiency of re-keying is a main factor that influences the performance of secure multicast.This paper presents a new key management algorithm to resolve the problem of high computation cost.The algorithm based on the membership of group is believable and choose a group leader to make a group key for the secure multicast, which introduces the key management algorithm into key agreement algorithm.The algorithm can reduce the computational complexity of group key generation, and improve the scalability of group key management algorithm.
