摘　　要：由于传感器节点的资源受限,导致无线传感器网络无法部署高强度的安全算法。因此,针对分层无线传感器网络,如何防御内部攻击,如何在考虑能量有效性的情况下,实现感知数据安全的传输就变得非常重要。改进基于二项分布的无线传感器网络信任评估系统(Improved Binomial-based Trust Management System, I-BTMS)。通过引入簇头的信任评价,解决第三方推荐的可信度问题;将I-BTMS输出的当前信任值,作为下一轮簇头选举的因素,同时考虑能量消耗,设计基于信任的分层无线传感器网络安全簇头选举方案(Trust-based Secure Cluster-Head Election Scheme, T-SCHES),形成有效的安全迭代。实验结果表明,所提I-BTMS可以有效地防御共谋攻击,T-SCHES实现了安全性与能效的均衡,提高网络安全性,延长网络生命周期。Due to the constrained resources of sensor node,the high-strength security algorithms cannot be deployed in a wireless sensor network(WSN).Therefore,for hierarchical WSN,how to defend against the internal attack and how to transmit the sensed data in secure by considering the energy consumption become very critical.The improved binomial-based trust management system(I-BTMS)is proposed.By adopting trust evaluation of cluster head(CH),the trustworthiness issue of third-party recommendations was solved.The current trust value output by I-BTMS was taken as an important factor for the CH election of next round,while considering energy consumption.A trust-based secure cluster head election scheme(T-SCHES)was designed.Thereby,effective security iteration was established.Experimental results show that the I-BTMS can effectively defend against collusion attacks,and T-SCHES achieves a trade-off between security and energy efficiency.Both of them can improve the network security and prolong the network lifetime simultaneously.
