摘　　要：针对伪随机数在密码应用中存在的安全性问题,基于超晶格物理熵源的特性,分析受激混沌作为熵源的优势,首次提出了将超晶格受激混沌振荡作为真随机数发生器熵源,利用12位ADC实现超晶格受激混沌信号的数字化采样,FPGA作为后处理单元,设计并实现了一种真随机、高性能、高速度的超晶格随机数发生器,实时生成随机数的速率达300 Mbit/s,该超晶格随机数性能可通过美国国家标准局所提供的标准(NIST SP 800-22)要求测试,结果表明该超晶格随机数具有良好的随机性。Aiming at the security problem of pseudo-random number in cryptographic applications,based on the characteristics of superlattice physical entropy source,this paper analyzes the advantages of stimulated chaos as entropy source,and proposes for the first time that the stimulated chaos oscillation of superlattice is used as entropy source of true random number generator,12bit ADC is used to realize digital sampling of stimulated chaos signal of superlattice,and FPGA is used as post-processing unit,a true random,high-performance and high-speed superlattice random number generator is designed and implemented.The real-time generation rate of random number is up to 300Mbit/s.The performance of the superlattice random number generator can pass the standard(NIST SP 800-22)provided by the National Bureau of standards.The results show that the superlattice random number has good randomness.
