A secure protocol for ultralightweight radio frequency identification (RFID) tags

Abstract

Recently, an ultra light weight protocol for RFID tags has been published. The advantage of this protocol was its low computation cost, but it fails in its security objectives, being vulnerable to several important attacks such as traceability, full disclosure, cloning and desynchronization. In this research, that protocol was enhanced and a new Ultralightweight RFID authentication protocol with mutual authentication was proposed, while keeping the computation cost low. The proposed protocol requires only simple bit-wise operations and can resist various attacks which the previous one could not. © 2011 Springer-Verlag.
