Cryptanalysis of two EPC-based RFID security schemes

摘要

Radio Frequency Identification (RFID) is an easy to use technology for quick and low-cost identification and authentication. Since RFID systems have found in various parts of our daily lives, security awareness about these systems has become one of the prominent topics for researchers. In this study, we investigate two RFID security schemes which both are under Electronic Product Code (EPC) standard. It is shown that both the analyzed protocols have some drawbacks and are vulnerable to several security attacks including secret parameters reveal, impersonation, reader forward secrecy and also one of them does not provide date integrity. In addition, in order to overcome all the discovered weaknesses, we propose some modifications and propose a modified version of each one.
