Analysis and Improvement of the Lightweight Mutual Authentication Protocol under EPC C-1 G-2 Standard

Abstract

Radio Frequency Identification (RFID) technology is a promising technology. It uses radio waves to identify objects. Through automatic and real-time data acquisition, this technology can give a great benefit to various industries by improving the efficiency of their operations. However, this ubiquitous technology has inherited problems in security and privacy. EPC Class 1 Generation 2 has served as the most popular standard for passive RFID tags. To improve the security of this standard, several protocols have been proposed compliant to this standard. In this paper we analyze the revised Yeh et al.’s(2010) protocol by Habibi et al.’s(2011) which is conforming to EPC-C1 G2 standard and is one of the most recent proposed protocols in this field. We discuss several drawbacks of this protocol, then we present our enhanced protocol which the security analysis showed that it can improve the security and privacy of RFID systems.
