The authors present an effective and secure mechanism for key distribution in Wireless Sensor Network (WSN). Wireless sensor network finds unique and special applications as compare to the WiFi, WiMax and etc networks because sensors are deployed in a very secret, hostile environment like battlefield, environmental monitoring, and health care industry. Various wireless sensor nodes are interconnected and form a wireless sensor network. Wireless sensor network are infrastructure less and can operating any environment as compare to the traditional network. WSN mainly consist of large number of tiny and simple nodes that are randomly deployed in operating areas unattended.
