用于SRAM PUFs的伪随机数发生器的FPGA实现
FPGA Implementation of Pseudo-Random Number Generator for SRAM PUFs
摘要
Abstract
The problem of information security is becoming serious,and the random numbers are the cornerstone of information security systems.This paper proposes a Hash-based pseudo-random number generator (PRNG) which takes static random access memory physical unclonable functions (SRAM PUFs) as entropy sources.This PRNG verifies the availability of entropy sources online and reseeds dynamically which improved the security of pseudo-random numbers.Therefore,it can be securely applied in high-level secure cryptographic protocols.This PRNG is implemented on FPGA development platform and the generation speed is up to 598.1Mbps.Experimental results of the NIST statistical test suite show that,the pseudo-random numbers generated by this PRNG pass all random tests and have good randomness.关键词
