An improved RFID security method with ownership transfer

Radio Frequency Identification (RFID) security gets more and more important as the RFID technology has been gaining popularity from public. In this paper, we proposed a simple and efficient improved security method for RFID tags supporting ownership transfer process. The proposed security method is based on Osaka et al.'s RFID security method, which has some security weaknesses. As a result, our proposed solution fixes these security flaws while maintaining the security and efficiency of the original method.
