Lightweight authentication for RFID used in VANETs

Abstract

This work addresses the critical problem of authentication in RFID. It describes a new lightweight scheme for mutual authentication between readers and tags that fulfills the EPCGen2 standard and all practical requirements of low-cost RFID such as resource limitation of tags and minimal interaction between tags and readers. Furthermore, the proposal does not rely on RFID readers as they are portable, and instead of that, it bases its security on trust in the back-end server because all shared secrets are stored only by the tag and the back-end server, with no possible access by the reader at any time. © 2012 Springer-Verlag.
