无线传感器网络节点定位中一种检测欺骗攻击的方法

摘要

Spoofing Attack is the easiest and most common way used by attackers. The vulnerabilities of Spoofing Attack were analyzed and summarized in this paper. Furthermore, an effective approach to monitoring and detecting such Spoofing Attacks was proposed. The detecting mechanism was based on the visualization of the consistency between the time of transmission and the loss of the power. The mathematical expression of the relationship between the time and the loss of power was derived. Experimental studies were conducted to investigate the effect of the algorithm. Simulation results verified the effectiveness of the method.%为了防御欺骗攻击、保障传感器节点定位的有效性和可靠性,分析、总结了欺骗攻击所固有的薄弱环节,在此基础上.提出一种检测欺骗攻击的算法.检测节点通过核对与被检测节点之间信号传播时间和所损耗的功率是否相对应,来判断是否存在检测攻击.推导了信号所传播时间和损耗功率的对应关系,并使用OPNET Modeler实现算法仿真,仿真实验证明该算法可以有效的检测出攻击节点,提高定位的精度.
