摘　　要：无线传感器网络由分布式部署的大量节点组成,容易成为恶意攻击的目标。为了确保节点能够提供高安全性的数据信息服务以及更高的隐私保护性能,并为合法查询者提供安全的数据查询服务,因此,提出高安全性无线传感器网络节点双向认证算法。根据建立的无线传感网络(Wireless Sensor Network,WSN)能量模型对WSN节点实施分簇处理,减少节点能耗;对分簇后的节点展开网络初始化、密钥协商以及节点信任度计算等认证前期处理,获取可信节点;采用数字签名的方式完成可信节点之间的双向认证,提高无线传感器网络的安全性。实验结果表明,所提方法在减少WSN节点认证时延和能耗的前提下,能够有效提高网络的生存节点。Generally,wireless sensor networks are composed of many nodes deployed in a distributed manner.However,they are susceptible to malicious attacks.In order to ensure that nodes can provide high-security data information services and higher privacy protection,as well as secure data query services for legitimate enquirers,this article presented a bidirectional authentication algorithm for wireless sensor network nodes with high security.Based on the Wireless Sensor Network(WSN) energy model,WSN nodes were divided into different clusters,thus reducing node energy consumption.After that,network initialization,key negotiation,and node trust calculation were performed on the clustered nodes to obtain trusted nodes.Moreover,digital signatures were adopted to achieve bidirectional authentication between trusted nodes.Finally,the security of wireless sensor networks was improved.Experimental results show that the proposed method can effectively improve the survival circle of WSN nodes while reducing authentication latency and energy consumption.
