摘　　要：无线传感器网络存在很多安全问题,节点间的信任关系难以确认。针对上述问题,采用模糊理论建立一种模糊信任模型解决节点间信任的评价、计算问题,并用该模糊信任模型解决无线传感器网络的路由安全问题。实验结果表明,该信任模型能有效评价节点的信任状态,抵御不良节点的丢包问题。As Wireless Sensor Network（WSN） deployed in the natural environment, the network faces many security problems and the trust relation between nodes is difficult to confirm. Aiming at the problem, a fuzzy trust model is established to deal with the trust evaluation and calculation problems between nodes by adopting fuzzy theory, and this fuzzy trust model is used to solve routing security issues for WSN. Experimental results show that the trust model can evaluate the trust status of the node effectively and resist packet loss of misbehavior nodes.
