Random numbers are indispensable resources for application in modern science and technology. Therefore, a dedicated entropy source is essential, particularly for cryptographic tasks and modern applications. In this work, we experimentally demonstrated a scheme to generate random numbers by multiplexing eight tunnel diodes onto a single circuit. As a result, the data rate of random number generation was significantly enhanced eightfold. In comparison to the original scheme that employed one diode, this multiplexing scheme produced data with higher entropy. These data were then post-processed with the Toeplitz-hashing extractor, yielding final outputs that achieved almost full entropy and passed the U.S. National Institute of Standards and Technology (NIST) Special Publication 800-90B validation. These data also passed the NIST Special Publication 800-22 statistical randomness examination and had no sign of patterns detected from an autocorrelation analysis.
随机数是现代科学技术应用中不可或缺的资源。因此，专用的熵源是必不可少的，特别是对于密码学任务和现代应用。在这项工作中，我们通过将八个隧道二极管多路复用到单个电路上，实验性地演示了一种生成随机数的方案。结果，随机数生成的数据速率显著提高了八倍。与原始方案中使用一个二极管相比，这种多路复用方案产生的数据具有更高的熵。然后使用 Toeplitz 哈希提取器对这些数据进行后处理，最终输出几乎达到了完全的熵，并通过了美国国家标准与技术研究院（NIST）特别出版物 800-90B 的验证。这些数据还通过了 NIST 特别出版物 800-22 统计随机性检验，并且在自相关分析中没有发现任何模式的迹象。
