Radio Frequency Identification (RFID) is a relatively new technology. In recent years, it has been shown to be convenient and feasible in many applications. However, there are security issues which need to be addressed. Due to the wireless transmission of the RFID system, malicious people can gain the information in the RFID tags, and the user’s privacy is invaded. Although there have been many protection methods proposed for RFID security, the system has remained vulnerable to various attacks. In this paper, we propose a conforming of the EPCglobal Class 1 Generation 2 standards RFID ownership transfer protocol with provable security. The proposed scheme can resist several attacks and ensure a secure transaction.
