Physical unclonability-based RFID lightweight class authentication method

Abstract

The invention discloses a physical unclonability-based RFID lightweight class authentication method, uses a PUF, a linear feedback shift register (LFSR), and XOR operation to perform processing, a label has small hardware requirements, cost is relatively low, the operation amount is small, and the method is resistant to various attacks including replay attack, impersonation attack, message stop attack, synchronization attack, wiretapping attack, physical attack, and label cloning, thereby effectively realizing forward security, and protecting privacy of a user. At the same time, through bidirectional authentication between a label and a reader, balance between efficiency and security is realized, hardware cost is well given consideration to, and thus the method is suitable for use of lowcost labels, and has relatively large practicability.

Description

technical field [0001] The invention relates to the communication field, in particular to an RFID lightweight authentication method based on physical unclonability. Background technique [0002] A PUF (Physical Unclonable Function) is a set of miniature delay circuits that generate an unpredictable response when it accepts an input, using random differences in its inevitable inherent physical structure. Since the differences produced by lithography, doping and other links in the manufacturing process of PUF chips are inherently inimitable and replicable, even chip manufacturers cannot replicate exactly the same PUF chips. [0003] LFSR (Linear Feedback Shift Register) is a mechanism used to generate a binary sequence. It consists of a shift register and an XOR unit. The number of general gate circuits is 300. [0004] RFID (Radio Frequency Identification) is an automatic identification technology that uses radio frequency signals or spatial coupling and reflection transmiss...

AI Technical Summary

Problems solved by technology

The RFID lightweight authentication method in the traditional solution requires relatively large hardware in order to achieve a certain level of security.

However, some PUF-based protocols currently proposed have relatively few hardware requirements, but most of them have various problems, such as inability to resist replay attacks, counterfeit attacks, message blocking attacks, and synchronization attacks. privacy protection
