Secure Communication Against Framing Attack in Wireless Sensor Network

Abstract

In Wireless sensor networks (WSNs) detecting clone nodes is a major challenge. Distributed Hash Table (DHT) is one of the protocols which efficiently detect the clone nodes. The detected clone information is to be disseminated to the other nodes (witness nodes) in the network. The malicious nodes in-between can frame innocent nodes as clone nodes and clone nods as innocent nodes. This is referred to as framing attack. Our objective is to overcome this by using a key management scheme called Differentiated Pre Key Distribution to in order to ensure secure communication between the nodes in a Zone based WSN. In this scheme different number of keys is distributed to different sensors to enhance the resilience of certain links which is exploited during routing where nodes route the clone information through the links which are more resilient. The performance evaluation shows that this scheme provides secure communication in disseminating the detected information between the nodes in the network.
