Wireless Sensor Network (WSN) is usually consisting of huge number of limited sensor devices which are communicated over the wireless media. There are a lot of its applications in military, health and industry. Many of WSN applications such as military and healthcare are critical and required certain level of security. Therefore, it is necessary to provide wireless sensor network not only with the acceptable reliability of services but also adequate level of security. As sensor devices are restricted, security in WSNs is a challenging task and the networks exposed to various kinds of attacks and conventional defenses against these attacks are not suitable.
