An efficient and secure RFID security method with ownership transfer

Radio Frequency Identification (RFID) has come under the spotlight as technology supporting ubiquitous society. But now, we face several security problems and challenges in RFID systems. Recent papers have reported that RFID systems have to achieve the following requirements: (1) Indistinguishability, (2) Forward Security, (3) Replay Attack, (4) Tag Killing, and (5) Ownership Transfer We have to design RFID system that achieves the above-mentioned requirements. The previous methods achieve only some of them individually, and no RFID system has been constructed that achieves all requirements. In this paper we propose an RFID security method that achieves all requirements based on a hash function and a symmetric key cryptosystem. In addition, our proposed method provides not only high-security but also high-efficiency.
