利用两个相互耦合的半导体激光器（MC-SLs）输出作为混沌熵源，演示并实验分析了一种产生Tbits/s超快物理随机比特（PRB）的方案。首先，从MC-SLs的两个混沌输出中并联得到两个熵源。其次，采用多种优化的后处理方法，从两个熵源中提取生成速率为0.56 Tbits/s的两个PRB流，并通过NIST特刊800-22统计检验验证其随机性。通过交错运算合并两组0.56 Tbits/s的PRB流，进一步得到满足NIST统计测试所有质量标准的第三组1.12 Tbits/s的PRB流。最后，在额外考虑最小熵的限制后，两个熵源的两组PRB流的生成速率仍然可以达到0.48 Tbits/s，然后合并的第三组PRB流的生成速率为0.96 Tbits/s。此外，在序列长度为10 Gbits的情况下，分析了三组PRB流的统计偏差和序列相关系数。(C) 2015美国光学学会
Using two mutually coupled semiconductor lasers (MC-SLs) outputs as chaotic entropy sources, a scheme for generating Tbits/s ultra-fast physical random bit (PRB) is demonstrated and analyzed experimentally. Firstly, two entropy sources originating from two chaotic outputs of MC-SLs are obtained in parallel. Secondly, by adopting multiple optimized post-processing methods, two PRB streams with the generation rate of 0.56 Tbits/s are extracted from the two entropy sources and their randomness are verified by using NIST Special Publication 800-22 statistical tests. Through merging the two sets of 0.56 Tbits/s PRB streams by an interleaving operation, a third set of 1.12 Tbits/s PRB stream, which meets all the quality criteria of NIST statistical tests, can be further acquired. Finally, after additionally taking into account the restriction of the min-entropy, the generation rate of two sets of PRB stream from the two entropy sources can still attain 0.48 Tbits/s, and then a third set of merging PRB stream is 0.96 Tbits/s. Moreover, for the sequence length of the order of 10 Gbits, the statistical bias and serial correlation coefficient of three sets of PRB streams are also analyzed. (C) 2015 Optical Society of America
