An Efficient and Scalable Re-authentication Protocol over Wireless Sensor Network

Abstract

Although wireless sensor network is considered as one of promising technologies for ubiquitous computing environment, more researches for re-authentication of mobile nodes in wireless sensor network are required due to user mobility, one of important properties in ubiquitous computing environment. As the citizens in a city can be mobile user in wireless sensor network and the resource of the sensor nodes is limited, scalability of re-authentication is important. In other words, re-authentication with less communication cost should be proposed. In this paper, we suggest an efficient method of membership verification for re-authentication of mobile node and show the performance analysis of our membership verification. Using this method, we propose an efficient and scalable re-authentication protocol over wireless sensor network. Also, we provide performance and security analysis of our protocol(1).
