针对无线传感器网络节点能量受限及部署环境恶劣所导致的典型网络攻击对数据安全带来的严重影响,提出了一种具有轻量级特性并能同时抵御多种典型网络攻击的信任感知安全路由机制(TSSRM).在深入分析网络攻击特点的基础上,从节点行为维度与能量维度构建了综合节点信任度计算模型,通过对多项QoS指标量化,实现安全路径选择算法的优化.性能分析与仿真结果表明,TSSRM可以同时实现无线传感器网络的安全性和高效性.%Aiming at the serious impact of the typical network attacks caused by the limited energy and the poor deploy-ment environment of wireless sensor network (WSN) on data transmission, a trust sensing based secure routing mechan-ism (TSSRM) with the lightweight characteristics and the ability to resist many common attacks simultaneously was proposed. Based on the analysis of the characteristics of network attack, the trust degree calculation model was con-structed by combining node's behavior with energy, at the same time the security route selection algorithm was also op-timized by taking trust degree and QoS metrics into account. Performance analysis and simulation results show that TSSRM can improve the security and effectiveness of WSN.
