Wireless sensor network contains sensor nodes having limited capabilities to sense, collect, and manipulate the data. The sensed data often need to be sent back to the base station for analysis. However, when the sensing field is too far from the base station, transmitting the data over long distances using multi-hop may weaken the security strength. There may be different types of attack which can modify the sensed data by capturing the intermediate nods. In this paper, the authors proposed a mutual authentication method based on public key distribution technique, which can be used to secure the sensor network and they will also analyze the impact of this method over the network performance.
