Dynamic Detection of Clone Attack in Wireless Sensor Networks

摘要

Wireless Sensor Networks (WSNs) is considered to be one of the promising technologies for ubiquitous computing environment. Enabling secure communication in among the nodes in a sensor network is a risky task. It is found that WSNs are prone to clone attacks that lead to many devastating effects. In clone attack, an attacker initially captures a node in the network and reprograms the node. In the later stage the adversary replicates the reprogrammed node and spread throughout the network for taking control over the network. There are few distributed solutions available for this problem. But the issues related to energy and memory demanding in any WSN protocol makes these solutions ineffective. In order to overcome these drawbacks, a lightweight, fast, efficient and mobile agent based security solution against cloning attack or replication attack is been proposed for WSNs.
