Remotely monitoring the location and enduring presence of valuable items in adversary-controlled environments presents significant challenges. In this article, we demonstrate a monitoring approach that leverages the gigahertz radio-wave scattering and absorption of a room and its contents, including a set of mirrors with random orientations placed inside, to remotely verify the absence of any disturbance over time. Our technique extends to large physical systems the application of physical unclonable functions for integrity protection. Its main applications are scenarios where parties are mutually distrustful and have privacy and security constraints. Examples range from the verification of nuclear arms-control treaties to the securing of currency, artwork, or data centers.
在敌方控制的环境中远程监控贵重物品的位置和持续存在情况面临重大挑战。在本文中，我们展示了一种监控方法，该方法利用房间及其内部物品（包括一组随机放置的镜子）的千兆赫兹无线电波散射和吸收，来远程验证随时间推移是否没有任何干扰。我们的技术将物理不可克隆功能在完整性保护方面的应用扩展到了大型物理系统。其主要应用场景是各方相互不信任且存在隐私和安全限制的情况。例子包括从核武器控制条约的核查到货币、艺术品或数据中心的安保。
