摘　　要：信任管理机制为保障无线传感器网络安全提供了一种有效方案,通过对节点的行为进行评价,建立整个网络的信任管理机制,对判断的恶意节点采用相应的限制措施来保障安全。文章以Beta概率密度分布函数的期望值作为信任值,优化网络分簇路由协议,可在保障网络能量高效利用的同时,有效提升整个网络的安全性。With the wide application of wireless sensor network, the realization of WSN energy efficiency and the protection of network security are facing great challenges. The trust management mechanism provides an effective scheme for the WSN security. By evaluating the behavior of nodes, the trust management mechanism of the whole network is established, and the corresponding restrictive measures are adopted to ensure the security of malicious nodes. In this paper, the expected value of Beta probability density distribution function is used as the trust value to optimize the network clustering routing protocol, which can ensure the efficient use of network energy and effectively improve the security of the whole network.
