An Improved Ownership Transfer for RFID Protocol

The ownership transfer problems occur during using the RFID tag. In view of the problems of the RFID tag ownership transfer protocol, such as security defects and high computational cost, an improved lightweight RFID tag ownership transfer protocol is proposed in this paper. The improved protocol does not depend on the trusted third party, so that the improved protocol has a wider application space. Using the challenge-response mechanism, the new owner of the tag introduces the counter count and performs the corresponding operation according to the value of count to solve the desynchronization attack problems. The analysis results show that the improved protocol not only satisfies the security requirements of the tag transfer, but also overcomes the security defects of desynchronization attack. Compared with the existing RFID tag ownership transfer protocols, this improved protocol has larger promotion in the aspect of security and efficiency.
