摘　　要：为提高无线传感器网络的安全性和节能性,提出一种基于信任的安全路由协议TSRP。根据新的直接信任值、间接信任值、挥发因子和剩余能量来计算邻居节点的综合信任值,以评估节点的安全指标,并快速地识别和排除发起黑洞攻击、选择性转发攻击、Hello洪泛攻击和槽洞攻击的恶意节点。sink针对难以发现的虫洞攻击,根据多条链路的链路质量、传输距离和跳数计算出最优路径以保证所选路由的安全性和节能性。仿真结果表明,与AODV和TBSRP相比,TSRP选择的最优路由有效地减少了每个节点的负载,降低了网络的延迟和丢包率。In order to improve the security and energy saving efficiency of wireless sensor networks,a Trust-aware wireless Sensor network secure Routing Protocol(TSRP)is proposed.Based on the new direct trust value,indirect trust value,volatilization factor and residual energy,the node calculates the comprehensive trust value of the neighboring node to evaluate the safety index of the node,and to quickly identify and eliminate malicious nodes that cause black hole attacks,selective forwarding attacks,Hello Flood attacks,and sinkhole attacks.As for covert wormhole attacks,the sink calculates the optimal path based on the link quality,transmission distance,and hop count of multiple links to ensure that the selected route is safe and energy efficient.The simulation results show that compared with AODV and TBSRP protocols,the optimal route selected by TSRP can effectively reduce the load of each node,and reduce the network delay and packet loss rate.
