【摘要】：信息安全问题日益突出,而随机数则是信息安全系统的基石.本文以哈希算法为核心设计了一种伪随机数发生器,其以静态随机存储器物理不可克隆函数(Static Random Access Memory Physical Unclonable Functions,SRAM PUFs)为熵源,能够产生大量的伪随机序列.通过对熵源有效性的在线监测以及对种子的动态重播操作,本文提出的用于SRAM PUFs的伪随机数发生器提高了伪随机序列的安全性,可应用于各种高安全等级加密系统中.该发生器在FPGA开发平台上得到实现,其发生速度达598.1Mbps.随机数检测套件NIST分析结果表明:该伪随机数发生器的输出通过了所有测试项目,具有良好的随机性.
[Abstract]:The problem of information security is becoming more and more prominent, and random number is the cornerstone of information security system. In this paper, a pseudorandom number generator is designed based on hashing algorithm. It uses static Random Access Memory Physical Unclonable functions as entropy source and can produce a large number of pseudorandom sequences. By on-line monitoring of entropy source effectiveness and dynamic replay of seeds, a pseudorandom number generator for SRAM PUFs is proposed to improve the security of pseudorandom sequences, which can be applied to various high security encryption systems. The generator is realized on FPGA development platform, and its generating speed is 598.1 Mbps. The results of NIST analysis show that the output of the pseudorandom number generator has passed all the test items and has good randomness.
