BVFG: Batch Verification Scheme for Filtering of Gang Injected False Data in Wireless Sensor Networks
Wireless sensor networks are usually deployed at hostile environments. So they are vulnerable to injecting false data attack. An adversary could compromise one or more sensor node and accesses all stored keying materials then inject the false data which causes energy wasted in en-route nodes. In this paper, the authors propose Batch Verification scheme (BVFG) to find gang injecting false data attack and filter the false data. With the proposed mechanism, injected bogus data can be early detected and filtered by en-route sensor nodes. Thus, it can be discovered the intruder before it reaches the sink. The proposed BVFG scheme could be effectively saving energy and avoid sink overhead.
