Wireless Sensor Network (WSN) consists of a large number of small, low cost sensor nodes which have limited computing and energy resources. As the wireless medium is characterized by its lousy nature, reliable communication is difficult to assume in the key distribution schemes. Therefore, self-healing is a good property for key distribution in wireless applications. How to establish secure session keys is one of the central tasks for wireless sensor network communications. General Key distribution schemes for traditional computer networks could not be directly shifted to wireless sensor network environments.
