Design & Verification Of Anti-crack Security Label Based On Switched-Capacitor SRAM Physical Unclonable Function

With the rapid development of information technology,RFID are widely used in Internet of Things applications.On security devices such as RFID,classic cryptographic algorithms and network security technologies have guaranteed information security to a certain extent,but this depends on powerful With a key management system,an attacker can easily crack security devices such as RFID through intrusive attacks and non-intrusive attacks,resulting in the leakage of keys.This paper focuses on RFID key management and authentication mechanism,researches SC-SRAM PUF digital key,zero-knowledge proof algorithm and other security technologies,and carries out multi-layer security enhancement of RFID tags to make it have strong anti-cracking ability.First,through theoretical and experimental analysis of the basic properties of PUF and the advantages and disadvantages of the current main PUF implementation,this paper preproed the PUF based on SC-SRAM;then,we realized the SC-SRAM PUF from the pre-design to the post-design using UMC28 HPC 28nm process,the SC-SRAM PUF is designed to prevent intrusive attacks and anti-porting attacks,and we verified the characteristics of the PUF such as randomness and uniqueness through Monte Carlo simulations.This SC-SRAM PUF average Intra Hamming distance reaches 50.12%,and its stability has reached 94%.By comparing with the typical PUF design,the PUF designed in this paper has reached the cutting-edge level.Next,this paper has analyzed and selected a variety of zero-knowledge proof algorithms.An authentication mechanism based on the intractable principle of large integer factorization was developed,and we carried out it by software modeling and simulation of the mechanism.Finally,the zero-knowledge proof authentication algorithm is combined with SC-SRAM PUF to form a complete RFID tag system,and we designed the digital circuits and verified it based on FPGA and Monte Carlo simulation.The RFID tag can meet the requirements of identification,authentication,tracking and anti-cracking in Io T applications.The embedded physical entity has good anti-porting attack performance,which is of great significance to the anti-counterfeiting of logistics goods and valuables.At the same time,its security principle also has a good application prospect in the currently widely used security processors.
