摘要：For multicast network security problem,we propose a key management scheme which is based on the communication cost of multicast members.The new scheme first uses Kruskal algorithm to construct inter-cluster head routing tree according to the communication distance and energy between nodes,and the star topology is generated among ordinary nodes and the cluster head within one cluster.Then the routing tree is mapped into logical key tree considering the relationship between sibling nodes,and the leaf nodes in key tree correspond with their own cluster head members.Finally,the dynamic join and deletion for multicast members is achieved.Theoretical analysis and Matlab simulation experiment show that the proposed scheme is applicable to large-scale multicast communication,and lowers the communication overhead of members while reducing the storage of members.
