应对虚假数据注入结合途中过滤与溯源追踪方法

摘要

对无线传感器网络中的虚假数据注入攻击问题进行了深入研究,并提出了切实可行的解决方案.本方案结合了途中过滤与溯源追踪的优点,它的核心思想是在数据报告中添加部分标记信息,汇聚节点将没有通过验证的数据报告加入溯源追踪集合中,收集到足够多数据报告后,便可以进行溯源追踪操作.同时,我们提出了一种更加均衡的分组方法及概率标记方法,实现了更好的性能.%We propose a practical solution- combining the en-route filtering and traceback method to solve the false data injection attack in the wireless sensor networks. The solution combining the advantages of the en-route and traceback schemes. Its core idea is to add some marking information to the data reports, and the sink node will add the unverified data reports to the traceback set. When collecting enough reports, it will execuate the traceback operation. Meanwhile, we propose a more balanced group scheme and a probabilistic marking method to improve the performance.
