Abstract: 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.
