### Paper: A Novel Mutual Authentication Scheme Based on Quadratic Residues for RFID Systems

Authors: Chung-Ju Chan 3 Jue-Sam Chou Guey-Chuen Lee URL: http://eprint.iacr.org/2007/224 Search ePrint Search Google In 2004, Ari Juels [1] proposed a Yoking-Proofs protocol for RFID systems. The aim is to permit tags to generate a proof which is verifiable off-line by a trusted entity even when the readers are potentially untrusted. However, we find that their protocol not only doesn’t possess the anonymity property but also suffers from both of the off-line and replay attacks. In 2006, Kirk H.M. Wong et al. [3] proposed an authentication scheme on RFID passive tags, attempting to as a standard for apparel products. Yet, to our view, their protocol suffers from the known-plaintext attack. In this paper, we first point out the weaknesses in the two above mentioned protocols. Then, we propose a novel efficient scheme which not only can achieve the mutual authentication between the server and tag but also possess the anonymity property needed in a RFID system.
