摘要
针对异构分组无线传感器网络结构和应用特点,在加密通信中使用组密钥和对密钥.组密钥使用基于双向散列链自愈组密钥分发方法按会话进行更新.网络中有直接通信需求的节点间都以双线性对方式建立对密钥.对密钥与组密钥相结合,以非交互方式按会话进行更新.分析表明:方案支持节点插入和撤销,安全高效,资源开销合理,适用于无线传感器集中式管理网络.
Group key and pair-wise key were used in key management of heterogeneous cluster wireless sensor networks based on the structure and applications of the network.The group keys would be updated each session according to dual directional hash chains based self-healing group key distribution scheme.Each pair of nodes that needs to communicate with the other established pair-wise key in the manner of bilinear pairings.Pair-wise keys would be also updated each session together with group keys in a non-interactive way.The analysis shows that the scheme supports node addition and revocation.And its good efficiency,high security performance and perfectly acceptable resource overhead make it attractive for centralized management of wireless sensor networks.
