无线传感器网络中的虫洞攻击和防御

Wormhole Attack and Defence in Wireless Sensor Networks

无线传感器网络被誉为21世纪三大技术之一,其安全问题受到了越来越多的关注。文章首先介绍了无线传感器网络的特征,分析了安全问题的根源,然后详细介绍了无线传感器网络中虫洞攻击的原理和破坏性,提出引入简化的marsh信任模型,将邻居节点以往表现作为信任评估的经验来源,通过具体分析确定节点的位置关系,从而避免传感器网络中的虫洞攻击,最后指出了下一步研究的方向。

Wireless sensor network （WSN） is known as one of the three major techniques in 21^st century, and its security issues have received much attention. This article presents the characteristics of wireless sensor networks, analyzes the roots of the security issues, and then describes in detail the theory of wormhole attack and its destructions. In this paper, the simplified Marsh model is introduced too. By gathering data from the events of neighbor nodes the node can evaluate the trustiness of its neighbor. Through concrete analysis, the location relationship of nodes must be determined, thus the wormhole attack in wireless sensor networks can be prevented. Finally, the future development is discussed.
