By using true random number (TRN) generators, encoding with the highest security can be realized. However, a completely secure strategy to transfer these TRNs has not yet been devised. Quantum key distribution (QKD) has attempted to establish secure key distribution methodology of this kind; however, several quantum cracking strategies have been predicted and experimentally demonstrated. In this work, COSMOCAT was invented as a solution for next-generation ultrahigh security near-field communications. With COSMOCAT, TRNs are generated from naturally occurring and ubiquitous cosmic-ray muons and the generated cosmic keys are distributed by these muons with an unprecedented level of security. The successful results of this experiment indicate that our prototype and the new key-generation-and-distribution standard can be utilized for practical encoding and near-field data transfer at rates of 10-100 Mbps. It is anticipated that COSMOCAT will be one of key techniques for future high security, near-field communication management.
通过使用真随机数（TRN）发生器，可以实现最高安全性的编码。然而，尚未设计出一种完全安全的传输这些TRN的策略。量子密钥分发（QKD）试图建立此类安全密钥分发方法；然而，已经预测并通过实验证明了几种量子破解策略。在这项工作中，COSMOCAT作为下一代超高安全性近场通信的解决方案而被发明。借助COSMOCAT，TRN由自然产生且无处不在的宇宙射线μ子生成，并且生成的宇宙密钥由这些μ子以前所未有的安全级别进行分发。该实验的成功结果表明，我们的原型和新的密钥生成与分发标准可用于10 - 100 Mbps速率的实际编码和近场数据传输。预计COSMOCAT将成为未来高安全性近场通信管理的关键技术之一。
