Abstract:

Aiming at the problem of limited information protection methods of current lightweight Radio Frequency Identification（RFID） encryption schemes, combined with a Physical Unclonable Function（PUF） composed of Resistive Random Access Memory（RRAM）, a new type of lightweight RFID mutual authentication protocol is proposed. A multi-level response encryption mechanism is used to implement the secure authentication processing between the reader and the tag. Combined with the RRAM PUF model, a special error correction processing method is adopted to improve the reliability of the PUF response and prevent information leakage. In addition, key update mechanisms and anomalous attack identification have been added to prevent threats such as tracking attacks and desynchronization attacks. Simulation, analysis and comparison results show that the protocol can effectively resist multiple attack methods, and has higher security and lower computational cost.
