An improved RFID protocol based on quadratic residues

Abstract

Nowadays, RFID has become very popular technology and applications in various fields. Restrictions of computation cause RFID have a security problem due to its light, fortunately, there is a lot of experts have proposed a number of ways to solve these problems such that the issues have been addressed. In 2008 ”Computer Network”, Chen et. al. proposed a novel mutual authentication scheme based on quadratic residues. Unfortunately, the paper is implicit some of the security problems, furthermore, the scheme may also be suffered from tracking problem. Therefore, we points out the weakness of CCS protocol and proposes a more secure RFID protocol.
