Adaptive security design with malicious node detection in cluster-based sensor networks

Distributed wireless sensor networks have problems on detecting and preventing malicious nodes, which always bring destructive threats and compromise multiple sensor nodes. Therefore, sensor networks need to support an authentication service for sensor identity and message transmission. Furthermore, intrusion detection and prevention schemes are always integrated in sensor security appliances so that they can enhance network security by discovering malicious or compromised nodes. This study provides adaptive security modules to improve secure communication of cluster-based sensor networks. A dynamic authentication scheme in the proposed primary security module enables existing nodes to authenticate new incoming nodes, triggering the establishment of secure links and broadcast authentication between neighboring nodes. This primary security design prevents intrusion from external malicious nodes using the authentication scheme. For advanced security design, the proposed intrusion detect...
