Abstract

In this paper, a novel method is proposed to generate high-quality chaotic signals using three cascade-coupled nano-lasers (NLs), and generate high-speed, high-quality random number sequences. The master NL (MNL) is subjected to optical feedback, and its output is injected into the intermediate NL (INL), which is further injected into the slave NL (SNL). In the simulation, we first adjust proper parameters so that the SNL generates a chaotic signal with a large bandwidth and time-delay signature concealment. After performing self-delayed differential processing on the chaotic signal, and utilizing an 8-bit analog-to-digital converter for sampling and quantization, followed by extraction of the m-bits least significant bit, the final random bit sequence is obtained. Finally, we use NIST SP 800-22 to test the generated random numbers. The results demonstrate that the obtained random number sequence successfully passed all tests specified by NIST SP 800-22.

基于级联耦合纳米激光系统的高质量随机比特生成技术

本文提出了一种利用三个级联耦合纳米激光器（NL）生成高质量混沌信号并生成高速、高质量随机数序列的新方法。主 NL（MNL）接受光反馈，其输出注入中间 NL（INL），中间 NL 再注入从 NL（SNL）。在仿真中，我们首先调整适当的参数，使 SNL 产生具有大带宽和时延特征隐蔽性的混沌信号。在对混沌信号进行自延迟差分处理后，利用 8 位模数转换器进行采样和量化，然后提取 m 位最小有效位，最终得到随机位序列。最后，我们使用 NIST SP 800-22 测试生成的随机数。结果表明，生成的随机数序列成功通过了 NIST SP 800-22 规定的所有测试。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
