Privacy and security require not only strong algorithms but also reliable and readily available sources of randomness. To tackle this problem, one of the causes of single-event upsets is the utilization of a non-deterministic entropy source, specifically ultra-high energy cosmic rays. An adapted prototype based on existing muon detection technology was used as the methodology during the experiment and tested for its statistical strength. Our results show that the random bit sequence extracted from the detections successfully passed established randomness tests. The detections correspond to cosmic rays recorded using a common smartphone during our experiment. Despite the limited sample, our work provides valuable insights into the use of ultra-high energy cosmic rays as an entropy source.
隐私和安全不仅需要强大的算法，还需要可靠且随时可用的随机数源。为了解决这个问题，单粒子翻转的原因之一是使用了非确定性熵源，特别是超高能宇宙射线。在实验过程中，采用了基于现有μ子探测技术的改进原型作为方法，并对其统计强度进行了测试。我们的结果表明，从探测中提取的随机比特序列成功通过了既定的随机性测试。这些探测对应于我们实验期间使用普通智能手机记录的宇宙射线。尽管样本有限，但我们的工作为将超高能宇宙射线用作熵源提供了有价值的见解。
