In secure multicast communication, group key management plays an essential role for the guarantee of data confidentiality and integrity. Because communication bandwidth is a limited resource, most group key management schemes for scalable secure multicast communications have focused on reducing the number of update messages, i.e., communication cost. To alleviate the scalability problem, a key tree structure was proposed and many group key management schemes have since adopted this approach… CONTINUE READING
