Security enhancement of authenticated RFID generation

Abstract

EPCglobal Class-1 Generation-2 specification (Gen2 in brief) has been approved as ISO18000-6C for global use, but the identity of tag (TID) is transmitted in plaintext which makes the tag traceable and clonable. In this paper we present a synchronization-based communication protocol based on Gen2, called Gen2+, for low-cost RFID tags. The class-1 Gen2+ RFID tag is a multiple round protocol and it supports only simple primitives like Pseudo-random Number Generator (PRNG) and cyclic Redundancy code (CRC) to achieve reader to tag authentication. Our protocol is more secured under tracing and cloning attack.
