摘要： A group key management method for secure multicast communication includes: creating a tree having a root node, internal nodes and leaf nodes to manage group keys of a receiver group by a group key management server; generating user keys of all nodes excluding the root node in the tree on the basis of Chinese Remainder Theorem; assigning the leaf nodes of the tree to users of the receiver group; and sending the user keys of the leaf nodes to the corresponding users for group key management. Further, the group key management method for secure multicast communication includes generating group keys of all non-leaf nodes; computing a solution of congruence equations based on the user key and group key by using Chinese Remainder Theorem for each non-leaf node; and multicasting a group key update message to each user of the respective leaf nodes.
