Wireless Sensor Networks (WSN) consists of many small sensor nodes that utilizes the sensors to collect sensor data and sends the data to the base station. Security in WSN has been a subject well researched for last few years and still many related researches are going on. Authentication with reconfiguration capability is a very important trait for the security of a network. The overall objective of this research is to develop a wireless sensor network which is reconfigurable and secure. I propose a reconfigurable authentication mechanism with on-line key changing capability using encryption. I discuss the types of attacks the proposed authentication can prevent and describe step by step implementation of this proposal in hardware. I compare AES with RC4 algorithm in my network setup and show how they react to RSSI, Latency and Throughput in variable parameters.
