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 is hailed as one of the three technologies in the 21st century, and its security issues have drawn more and more attention. Firstly, this paper introduces the characteristics of wireless sensor networks, analyzes the root causes of the security problems, and then introduces the principle and destructiveness of wormhole attacks in wireless sensor networks in detail. The paper introduces a simplified marsh trust model and uses the past performance of neighbor nodes as a trust assessment The source of experience, through the specific analysis to determine the location of nodes, in order to avoid wormhole attack in the sensor network, and finally pointed out the direction of the next step of the study.
