Abstract:

Security authentication protocol is an important means to solve the forward channel security and identity identification problems of radio frequency identification (RFID) system. In view of the insecure problem of RFID system tags and reader channels and the vulnerability of tags to physical attacks, combining physical unclonable function (PUF) technology with traditional RFID security protocol, a PUF-based anti-physical cloning RFID protocol is proposed. The communication primitives are guaranteed by the two cryptographic primitives PUF and hash function, all communication of the protocol is encrypted to ensure the exclusiveness and security of the information, and the label information and the key information are updated after each round of authentication. The analysis results of protocol performance show that, the proposed protocol can prevent not only eavesdropping, tampering, replay attacks, but also physical attacks and tag clone attacks, thus improving the security of RFID system. At the same time, the proposed protocol does not take up too much resources and can be applied to low-cost resource-constrained RFID systems.

Key words: RFID system, security authentication protocol, resistance to physical cloning, physical unclonable function
