SURVEY: AUTHENTICATION AND KEY DISTRIBUTION SCHEMES FOR WIRELESS SENSORS NETWORK
S.P. Goel, Manjeet Behniwal, Ajay K. Sharma · 2013
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. Therefore, security services, such as, authentication and key establishment between sensor nodes, are important. However, the resource constraints of the sensors and their nature of communication over a wireless medium make data confidentiality and integrity a nontrivial task. In this paper we proposed a mutual authentication method based on public key distribution technique, which can be used to secure the sensor network and we will also analyze the impact of this method over the network performance.
