摘要
Abstract
LKH method is an efficient multicast key update technology.But during the rekey process in this method,encryp-tion and transmission overhead often become a bottleneck in the communication system.Through the study of the above issue, this paper developed a heuristic search algorithm to construct an optimal key tree structure.Different from the traditional LKH key tree structure,the branching factor of this approach could take on different values at each level of tree,so the new struc-ture could reduce the rekey overhead.The experimental results show that the scheme can efficiently reduce the encryption overhead,transmission overhead and the storage of keys in the system during the rekey process.关键词
