Radio-frequency identification (RFID) has become the center of attention in automatic identification technology. However, many security problems still could be found in the system design. Recent researches have pointed out the applications of RFID to ownership transfer, but these applications cannot achieve the Electronic Product Code (EPC) Class-1 Generation-2 standards. In this paper, we propose an ideal RFID system, which conforms EPCglobal Class-1 Generation-2 standards ownership transfer. The system accomplished the functions including mutual authentication, guarantee of privacy, conformation to EPCglobal Class-1 Generation-2 industry standards, and prevention of any third party attack. The features in our method are to ensure the transaction security as well as protect the privacy.
