| 摘 要： | 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。

| Abstract: | A high speed random bit generator is proposed with chaotic semiconductor laser used as the entropy source.Analogue-to-digital conversion is realized by high frequency electronic devices such as amplifier,comparator,and trigger.One bit sequence is generated and exclusive OR(XOR) operated with other different bit sequences,and data processing in computer is needless.The generator outputs a 500 Mb/s random bit sequence.The obtained sequence passed the statistic test of national institute of standards and techn... |
