Wireless Sensor-Based Enhanced Security Protocol to Prevent Node Cloning Attack

Wireless sensor network is the collection of low-power, independent wireless sensor node. Wireless sensor networks are generally deployed in mission-critical environment like battlefield surveillance, industrial process monitoring, etc. The nodes in the network are generally unattended by humans and hostile environment in which they are deployed to make the node vulnerable to many security attacks. One such attack is the node cloning attack, where the attacker will create the clone or replica of Legitimate Node by copying its cryptographic information into the clone node. Using the copied cryptographic information, clone node can further launch range of attacks in network like eavesdropping or raising false alarm, etc. In this paper, we have discussed the security protocol to prevent the clone node from implementing any successful attack in network. The security protocol is designed in such a way that it prevents the attacker from gaining the required cryptographic information. This is achieved by storing the partial cryptographic information which can only be completed by Legitimate Node. Node will be using location-based information to generate complete cryptographic information.
