论证了基于单个激光混沌信号作为物理熵源产生高速实时物理随机码的发生装置。搭建了全光纤结构的激光混沌源,输出强度随机起伏的光信号,经T型连接器分为两路,被差分ADC作用后,输出二进制比特流;利用延迟异或技术消除弱周期性后,可实时产生高质物理随机码序列,该序列码率达4.5Gbit/s。后续分析表明,所获得的随机码是统计无偏且不相关的,并可成功通过随机数行业测试标准。
The generation device of high speed real-time physical random code based on single laser chaotic signal as physical entropy source is demonstrated. A full-fiber chaotic laser source is constructed. The optical signal with random fluctuation is output and divided into two channels by the T-connector. After being differentiated by the ADC, the binary bit stream is output. After the weak periodicity is eliminated by using the delayed XOR technique, Real-time generation of high-quality physical random code sequence, the sequence rate 4.5Gbit / s. Subsequent analysis shows that the obtained random code is unbiased and uncorrelated and can successfully pass the random number industry test standard.
