基于光反馈半导体激光器产生混沌激光作为熵源,设计制作了放大器、比较器及触发器等高频电子器件,实现对混沌激光的模数转换,产生一路随机数,与另一路不相关的随机数异或处理,无需后续数字处理,最快可实现500 Mb/s输出。产生的随机数序列通过了美国国家标准与技术研究院(NIST)的统计测试标准(SP800-22)。该随机数发生器码率可调,易集成,有利于产品化。 Based on the optical feedback semiconductor laser to generate chaotic laser as the entropy source, high-frequency electronic devices such as amplifiers, comparators and flip-flops are designed and manufactured to realize the analog-digital conversion of chaotic laser to generate all random numbers, which are not related to the other way Exclusive or processing, no subsequent digital processing, the fastest 500 Mb / s output can be achieved. The resulting sequence of random numbers passed the National Institute of Standards and Technology (NIST) statistical test standard (SP800-22). The random number generator rate is adjustable, easy integration, is conducive to product.
