Wireless Sensor Networks (WSNs) are used in many applications in military, ecological and health-related areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. The cost constraints, invisible deployments will result in small sized, resource-constrained sensor nodes. While the set of challenges in sensor networks are diverse, the authors focus on security of wireless sensor network in this paper. They propose some of the security goal for wireless sensor network.
