Security is a matter of extensive research interest with widespread deployment of WSN (Wireless Sensor Network) in various real life applications. Unreliable wireless communication, physically insecure locations and resource exhaustion attacks render sensor vulnerable to several security breaches. Sensors are supposed to operate on battery in hostile and unattended environment over a longer span of time. Taking into consideration conflict in interest between security and energy consumption, effective security implementation is non-trivial in WSN. A number of security schemes were presented in literature for ad hoc networks.
