摘要：Sensor networks serving mission-critical applications are potential targets for malicious attacks. Although a number of recent research efforts have addressed security issues such as node authentication, data secrecy and integrity, they provide no protection against falsely injected sensing reports once any single node is compromised. In this paper we present a geometric En-route Filtering mechanism (GEF). GEF exploits the sheer scale and dense deployment of large sensor networks. GEF aims at detecting and dropping such falsely injected reports by compromised nodes. It takes advantage of the large scale and dense deployment of sensor networks. GEF’s detection and filtering power increases with the deployment density and the sensor field size.
