Distributed wireless sensor networks often suffer problems on detecting malicious nodes, which always bring destructive threats. Thus, sensor networks have to supply authentication services for sensor identity and data communication. As matter of fact, 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 paper provides adaptive security modules to improve secure communication in distributed sensor networks. The primary security module provides online identity authentication services to new incoming sensor nodes which being distributed after initial deployment.
