Wireless Sensor Networks (WSNs) are gaining more importance in area of research and development. Because of its wide range of applications and usage of less battery power. Despite making such sensor networks possible, the very wireless nature of the sensors presents a number of security threats when deployed for certain applications like military, surveillances etc. The problem of security is due to the wireless nature of the sensor networks and constrained nature of resources on the wireless sensor nodes.
