A pairwise key predistribution scheme for wireless sensor networks.

Wireless Sensor Network (WSN) is the well growing technology in the fields of defence, industrial automation, building automation, environmental forecasting, asset management, health care etc. In WSN, each and every node should be secured and this security is achieved by secure group communication. There are many key management techniques used to implement group communication in a secured manner but the key distribution is always being an issue in WSN because of limited capabilities and vulnerable nature of WSN. The proposed WSN totally uses three sort of keys namely Master key, session key and pair wise keys for secured communication are used in WSN. The main goal is to provide secured node to node communication by using efficient pair wise keying mechanism and it uses secret code for secure communication. It provides the better robustness, authentication and more security. The …
