REPUTATION BASED ZONE TRUST DETECTION AND SWATT REVOCATION METHOD USING SPRT IN SENSOR NETWORKS

Abstract

Wireless sensor networks can be used in several real world applications, including various critical applications such as military surveillance, infrastructure security monitoring and fault detection. Typically sensors are deployed in large number in environments that may not be safe or easily accessible to humans. An adversary or attacker can modify the sensor nodes that operate in the harsh environment and thus can insert faulty data to mislead the whole network. Hence in order to reduce the damage occurred to the compromised sensor nodes, it is extremely important to detect and revoke them as early as possible. The main idea is to propose zone based node compromise detection and revocation scheme for sensor networks. This is achieved using reputation based trust management scheme and software based attestation technique. Software attestation technique has been proposed to verify the integrity of the code without physical access. Whereas Reputation-based Framework for Sensor Networks maintain reputation for other nodes. This reputation is used to evaluate the trustworthiness of other nodes, which in turn establishes a web of trust in the network, which is then used as an inherent aspect in predicting the future behaviour of nodes in the network. Thus the proposed scheme provides effective and robust compromised sensor node detection and revocation capability with little overhead.
