A Design and Implementation of Wireless Sensor Network Security on Nano-Qplus Platform

The sensor network features characteristics such as nodes being densely distributed, large quantities of nodes being scattered around, necessity of frequently changing the network topology as well as utilizing broadcasting system for communication. It also reflects a wireless network environment where batteries and computing powers are limited that it would be difficult to even make a decision on whether surrounding nodes are in credible conditions. Not only the numbers of nodes through which sensor nodes communicate exceed one, but additional research on password key control is required. It would be used on mutual authentication between nodes as well as authentication and enciphering by using limited sensor resources within the sensor network, which is based on the mesh structure. This paper makes statements on encryption algorithm, key management, security protocol, authentication and essential security elements of secure routing. It will be acting as basis of developing security mechanism, which will provide confidentiality of the MAC class level, authentication and integrity on a sensor network environment referred as the nano-Qplus platform.
