摘　　要：针对传统的真随机数发生器(TRNG)的频率随级数线性减小,对工作环境、电压和工艺变化非常敏感,鲁棒性不强等问题,提出一种新型的真随机数发生器结构,通过使用多相位自定时振荡环作为熵源,重新设计熵源采样电路以配合熵源结构,实现高采样输出的要求。本文提出的真随机数发生器运行在Xilinx KCU116平台上拥有高达250 Mbps的产生速率,消耗资源低至32 slice。通过对产生数据进行了统计检验分析,其统计结果以高P值通过了美国国家标准与技术研究院(NIST)测试套件的检测。Aiming at the problem that frequency of traditional true random number generator(TRNG)decreases linearly with the stages,and is very sensitive to the changes of the working environment,voltage and process,and its robustness is not strong,a new structure of TRNG is proposed.By using multi-phase self-timed ring as the entropy source,the entropy source circuit is redesigned to match entropy source structure to realize the requirements of high sampling output.The proposed TRNG runs on the Xilinx KCU116 platform with a production rate of 250 Mbps and resource is consumed as low as 32 slices.Through the statistical test and analysis of the generated data,the statistical results passed the National Institute of Standards and Technology(NIST)test suite with high P-value.
