A Study of Bilinear Maps in Wireless Sensor Networks

Abstract

In the past, a large part of security requirements of wireless sensor networks (WSN) were fulfilled by symmetric cryptography systems. But, today by introduction of new needs in these networks and their security development, researchers of security and cryptography try to find new ways to increase efficiency and security of wireless sensor networks. Improving computational power of sensors used in wireless sensor networks made application of public key cryptography in WSN possible. Identity based cryptography is one important type of public key cryptography which using some bilinear functions called pairing functions was seriously applied. In this paper we will look at some researches done to find how to use pairings in wireless sensor networks.
