【摘要】 通过深入分析有线网络组密钥管理方案,结合无线网络的特点,提出一种基于 Ad hoc 网络的分层组密钥管理方案。该方案具有两层管理结构,将密钥更新限制在各簇内,可以提高更新效率, 减小系统开销.通过与逻辑密钥树方案在通信开销等方面的对比,证明此方案更加有效。更多还原

【Abstract】 Through in-depth analysis of cable network group key management program with the relevant characteristics of the wireless network,this paper proposes a hierarchical multicast group key management based on Ad hoc network.The program has a two-tier management structure,in which the key updating is confined in one cluster,thereby it increases the efficiency of key updating,and reduces the system cost. Compared with logic key tree program in communication cost,it proves that this program is more effective.更多还原
