An Approach to Identify Node Clones in Wireless Sensor Networks
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 4
Abstract
Sensor nodes that are deployed in hostile environments are susceptible to capture and compromise. An adversary may gain private information from these sensors, clone and logically deploy them in the network to launch a variety of insider attacks. This attack process is generally termed as a clone attack. Currently, the defenses against clone attacks are not only very few, but also suffer from selective interruption of detection and high overhead (computation and memory). In this paper, we propose a new effective and proficient scheme, called SET, to identify such clone attacks. The key idea of SET is to identify clones by computing set operations (intersection and union) of exclusive subsets in the network. First, SET securely forms exclusive unit subsets among one-hop neighbors in the network in a distributed way. This secure subset formation also provides the authentication of nodes’ subset membership. SET then employs a tree structure to compute non overlapped set operations and incorporates interleaved authentication to prevent unauthorized falsification of subset information during forwarding. Randomization is used to further make the exclusive subset and tree formation unpredictable to an adversary.
