| 摘 要： | 在无线网络环境中,在对一组用户服务时,需要为其分配一个组共享密钥。好的密钥管理方案可以极大减少网络通信量,提高系统效率。论文分析了密钥管理的现状及存在的问题,然后提出了一种无线网络中基于物理拓扑结构的逻辑密钥树方案,并对此方案进行设计和性能分析,仿真结果表明此方案能有效减少网络通信量。

| Abstract: | In the wireless environment,we need to allocate a group key for everyone in the group in some kinds of service.An excellent key management schemes can efficiently reduce the communication burden,improve the system performance.In this paper,we analyze the state and the problem of existing key management schemes,then propose a Logical Key Tree scheme based on physic topology.we design the scheme and evaluate the performance.Simulation results show that this scheme can reduce communication burden efficiently. |
