Abstract: In view of the existing RFID authentication protocol is insufficient in the security authentication process due to the flaws in the design of the protocol, this paper presented an improved lightweight RFID authentication protocol using synchronized random number and PUF. It first proposed a desynchronizing attack method on RFID protocols, and analyzed the reason.Then it enhanced the protocol's ability to resist desynchronization attacks by setting a synchronized random number at both ends of the tag and reader.Finally, it introduced the PUF in the tag, used the PUF’s non-clonality to improve the tag’s anti-attack capability. The analysis results show that the new protocol can effectively resist multiple attacks, and it has higher security while ensuring certain efficiency and overhead.
