Wireless communication provides flexibility and power for communication while at the same time gives much more power to attackers to break into the systems. Sensors are small low powered devices that are used for applications such as monitoring environmental factors and identification. A sensor networks consists of a collection of sensor, connected through wireless communication with the aim of providing a specific service. Security of sensor networks not only includes protection against traditional attacks but also new attacks that are specific to sensors including easy loss of sensors and the need to use weaker security primitives to cope with low sensor power..
