摘要
提出了一种基于地理位置的虚假数据过滤方案GFFS。在GFFS中,节点在部署后将地理位置预分发给部分其他节点存储,每个数据报告必须包含t个具有不同密钥分区检测节点的MAC以及地理位置,转发节点既对数据分组中包含的MAC和地理位置的正确性进行验证,还对地理位置的合法性进行验证。理论分析及仿真实验表明,GFFS能有效地过滤不同地理区域的多个妥协节点协同伪造的虚假数据,且具备远强于已有方案的妥协容忍能力。
A geographical information based false reports filtering scheme (GFFS) in sensor networks was presented. In GFFS, each node distributes its location information to some other nodes after deployment. When a report was generated for an observed event, it must carry not only MACs from t detecting nodes with distinct key partitions, but also locations of these nodes. Each forwarding node checks not only the correctness of the MAC and the locations carried in the report, but also the legitimacy of the locations. Analysis and simulation results demonstrate that GFFS can resist collaborative false data injection attacks and thus can tolerate much more compromised nodes than existing schemes.
