在研究空中超表面无线回程链路的安全漏洞的基础上，首次定义并论证了“远程超表面攻击”(Remote PositionedMetaSurface-Done，RMD)攻击。在攻击中，对手Eve远程接近难以到达的无线回程链路，例如，塔之间，并秘密操纵高度定向的动态回程传输，实现远程窃听。在这里，我们展示了[1]的关键方面，包括轻量级无功率透射式无人机衍射亚表面的设计和制造。我们还演示了该攻击在亚太赫兹无线网络上的实现，展示了一段RMD攻击实验的视频。我们的结果表明，攻击者可以有效地拦截回程传输，同时在合法通信中留下最小的能量足迹。
Investigating the security vulnerabilities of wireless backhaul links to aerial metasurfaces, we define and demonstrate for the first time "Remotely PositionedMetaSurface-Drone"(RMD)attack in our paper [1]. In the attack, the adversary Eve remotely approaches hard-to-reach wireless backhaul links, e.g., between towers, and secretly manipulates highly directive backhaul transmissions on-the-fly, enabling remote eavesdropping. Here, we show the key aspects of [1], including the design and fabrication of the lightweight power-free transmissive on-drone diffractive metasurface. We also demonstrate the implementation of the attack on sub-THz wireless networks, presenting a video of RMD attack experiments. Our results reveal that the attacker can effectively intercept backhaul transmissions while leaving a minimal energy footprint on legitimate communication.
