Wireless sensor networks consist of hundreds or thousands of low cost, low power and self-organizing nodes which are highly distributed. As wireless sensor networks continue to grow, so does the need for effective security mechanisms because sensor networks may interact with sensitive data. Encryption algorithms play good roles in Information Security System (ISS). Those algorithms consume a significant amount of computing resources such as battery power. Wireless sensor networks are powered by a battery which is a very limited resource.
