一种面向PUF的模糊提取器设计与实现
Design and implementation of fuzzy extractor for PUF
摘要
Abstract
The physical unclonable function(PUF)implemented on SRAM and other schemes exists inherent demerit of poor reproducibility for environmental factors such as voltage changes and thermal noise.This disadvantage greatly restricts functional application in cryptography,communication and other fields.In this paper,a fuzzy extractor with large error correction capacity is designed to reconstruct the original data of SRAM by means of BCH codes(Bose-Chaudhuri-Hocquenghem Codes).The SRAM PUF chip applying this design is manufactured on the Hua Hong Grace 0.11 µm CMOS platform with area of 306 267 pan2.The original BCH code has a code length of 127 bits and an error correction capability of 27 bits,which achieves the practical requirements of PUF applications.关键词
