A Trusted Chain Build Scheme for Enhancing Network Security

Wireless sensor networks are increasingly gaining acceptance over the special scene as they provide an infrastructure for probing and transmitting especial information. The open nature of sensor networks exposes a number of security vulnerabilities including the problem of finding reliable trustworthy communication partners. In this paper, we propose trust chain build scheme which provides a trust computation framework by building reputation in decentralized sensor networks. Single node reports its current snapshot to cluster head node which evaluates trustworthiness of it. Cluster head node also will be scored by command node in the light of its behavior. Then a trust chain from sensor node to cluster head node comes into being.
