In clustering wireless sensor network (WSN), within the cluster nodes will often for multicast, to guarantee the security of message and node information, this paper designs a flexible and efficient group key management scheme. In this scheme, the calculation of the initial set of keys and node exit group key update, is improved based on the identity of the broadcast encryption algorithms, the algorithm to further reduce the length of the broadcast message, reduce transport energy consumption; The new node to join and the key at the end of life period of group key update, using symmetric encryption method of energy consumption is small. This scheme can resist conspiracy attacks, counterfeit attack. Under the same security standard, compared with other schemes such as EGKAS, this scheme takes up less storage space, lower energy consumption, and storage and group key update is independent of the size, has a good scalability.
