%X This paper proposed a refined key link-tree based group rekeying algorithm that is suitable for wireless sensor networks. By incorporating problem key paths into the key link tree-based group key management scheme and delaying the key update operations in problem key paths, the number of duplicate key update messages for auxiliary nodes could be reduced.The experimental results show the algorithm requires fewer rekeying messages and costs less power in the node adding and deleting operations than the existing group key management schemes.
