| Abstract: | A scheme on dynamic key production based on computation was proposed. Compared with the traditional LKH tree-based key management scheme, it reduced the number of keys for key management and the communication amount when rekeying. The security of the algorithm and its efficiency were analyzed. The key management based on this algorithm was proved to be safe and feasible. This scheme was suitable for the large scale group. |
