Radio Frequency Identification (RFID) is a new technology. In recent years, it is convenient and feasible in many applications. However, it also addresses many security issues which are worth discussing. Due to RFID system uses wireless transmission, there are some malicious peoples who want to get the information in the RFID tags around the environment, and the user’s privacy would be invaded. Although there have been many protection methods were proposed for RFID security, many researches still suffered from various attacks. In this paper, we propose a conformation of 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 via a serial of conscientious and careful proof.
