摘要
针对带执行器节点的无线传感器网络的安全通信问题,提出了一种新的密钥预分配方案.充分利用执行器节点具有能量充足、存储器资源丰富、较强计算和通信能力等特点,构建一棵以Sink为根节点、执行器节点为分支节点、传感器节点为叶子节点的密钥管理树,实现集中式和分布式密钥管理的安全通信机制.该分配策略包括三个阶段:初始化阶段、共享密钥发现阶段和安全路径建立阶段.重点论述如何构建密钥管理树,以实现通信的安全认证.讨论了添加或删除网络节点时的密钥管理自适应能力.
In order to solve security of communication in wireless sensor and actor networks,a new scheme of key pre-distribution was presented.To achieve the distributed and integrated secure communication scheme,the paper described a construction of the key management tree which maked sink for root node,actor for branch node,and sensor for leaf node by making use of the actor nodes′ sufficient energy capabilities,larger memory,better processing and communication capabilities.The scheme consisted of three phases,name...
