Group Key Management Based on B-Tree and LKH
Abstract: The existing secure group schemes had following shortages: 1) Individual has to maintain large amount of keys with increasing number of users; 2) There will be too many key renew process affecting the efficiency. This paper proposes an efficient group key management scheme based on B-Tree and LKH, which can add branches into the tree when new members join in order to impose restrictions on height of tree, and reduce the number of stored key. In this scheme, the group key will be renewed when the secure group members join or quit in order to provide a safe multicast module. This scheme overcomes the above defects and improves the performance under large group size, and could appropriately be applied on large and dynamic multicast groups.
