无线传感器网络(WSNs)路由安全问题的现状与对策研究

笔者对比分析了无线传感器网络(WSNs)安全体系结构的组成;讨论了限制无线传感器网络安全的各种因素以及安全评估的目标;在分析现有路由协议的基础上,从路由安全的攻防角度入手,详细阐述了现有各种路由攻击手段的原理、特点及危害,并给出了相应的攻击示意框图;有针对性地提出一些相应的安全防范对策,为WSNs安全路由的设计与实现提供了一些思路。

Current Status of Routing Security of WSNs and Its Countermeasures

The composition of the security system of WSNs(wireless sensor networks) is comparatively analyzed.The factors affecting the security of WSNs and its security assessment target are discussed.On the basis of the analysis of current routing protocols and from the aspects of attack and defence,the principles,characteristics and harms of all attack means are introduced as well as corresponding attack figures.Finally,corresponding countermeasures are proposed,which provides thinking idea for the design and implementation of routing security in WSNs.
