Abstract: Aiming at the problems that the traditional false data filtering methods can’t filter false data injection attacks from non-forwarding areas of compromised nodes, this paper proposes a forwarding path-undependent filtering scheme in wireless sensor networks. In PFDF, a global key pool is constructed according to the expected keys-sharing degree, and each node initializes a key before deployment. Analysis and simulation results demonstrate that PFDF can resist false data injection attacks from non-forwarding areas of compromised nodes, and consumes less energy than existing schemes.

摘要: 针对传统虚假数据过滤方法无法过滤从非转发区域注入虚假数据的问题,提出了一种不依赖转发路径的过滤方案PFDF。在PFDF中,基于期望的密钥共享度灵活构建密钥池,在部署前进行密钥分发。理论分析及仿真实验表明,PFDF能有效防范非转发区域的虚假数据注入攻击,并具备较低的能量开销。
