中文摘要：

虚假数据攻击不仅误导基站做出错误的决定，同时也会耗尽宝贵的网络资源。提出了一个鲁棒性虚假数据过滤方案（a Robust Filtering False Datescheme，RFFD）。该方案主要包括一个密钥管理架构及与之对应的虚假数据过滤安全机制两个部分。理论分析和模拟实验表明，与SEF方案相比，RFFD方案过滤虚假数据包的性能显著提高。

英文摘要：

False data injection attacks not only cause Base Station（BS） to make wrong decisions, but also drain out the significant sensor network resources. A Robust Filtering False Date Scheme （RFFD） is proposed. The scheme consists of two major components： one is the underlying key management framework and the other is the filtering false data security mechanism. Theoretical analysis and simulation results show that RFFD scheme can substantially improve the capacity of filtering false data packets compared with SEF scheme.
