摘要: 节能和安全是无线传感器网络应用中的一对矛盾需求,为调和这对矛盾,提出了一种能量有效的无线传感器网络安全拓扑控制协议(energy-efficient secure topology control protocol,ESTCP)。ESTCP首先根据节点地理位置形成结构化的网格拓扑;其次,通过单向哈希密钥链技术和对称密钥认证技术控制新节点在不同情形下的安全加入,通过新节点间形成临时簇减少因认证新节点带来的能量损耗。分析和仿真表明,ES-TCP在较少的资源开销下有效保证了拓扑控制的安全性。Abstract: Saving energy and security are a pair of contradictions demand of application research in wireless sensor networks(WSN).In order to reconcile this pair of contradictions,energy-efficient secure topology control protocol(ESTCP),an energy-efficient secure topology control protocol for wireless sensor networks is presented.In ESTCP,structured topology is formed according to node locations.In order to control new nodes in different situations securely adding to network,techniques of one way hash chain and symmetric cryptographic key are adopted in ESTCP.And temporal clusters are formed among new nodes for reducing energy consumption caused by new nodes authentication.Analysis and simulation results show that ESTCP effectively guarantees the security of topology control in consuming less resource.
