Reconfigurable intelligent surfaces (RISs) are designed to dynamically adjust the radio frequency (RF) environment to improve signal quality and coverage. It will be a critical component of the next generation (Next G) millimeter-wave (mmWave) wireless communication. However, RISs can also be conveniently manipulated by an attacker for malicious purposes such as gaining eavesdropping advantages, degrading wireless link quality, or poisoning channel estimation. These attacks will severely impact the availability, integrity, and security of Next G communication systems. Since the attackers can potentially alter the RF propagation environment at physical layer, conventional data encryption or authentication mechanisms at the data layer are not useful. To defeat these attacks, the project will carry out four tightly connected research thrusts at the physical layer: (i) to investigate and create RIS signal watermark embedding and signature appending to enable efficient and robust RIS signal/propagation path authentication, (ii) to localize malicious RISs through collaborative sensing for spectrum enforcement, (iii) to leverage neural network-based beamforming for low-probability-of-intercept and resilient RIS-assisted communication, and (iv) to build a mmWave testbed including the fabrication of a RIS and carry out experimental evaluation. This project’s novelty is on creating physical layer security building blocks to protect RIS-assisted mmWave communication. The broader significance and importance are: (i) to lay the secure foundations of RIS-assisted communication, (ii) to securing RF communication in different frequency bands and paradigms, including backscatter and symbiotic communications, (iii) to contribute to the roadmap and standardization efforts of Next G Alliance, and (iv) to broaden the participation of underrepresented groups through various internship and outreach programs offered at participating universities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

可重构智能表面（RIS）旨在动态调整射频（RF）环境，以提高信号质量和覆盖范围，它将成为下一代（Next G）毫米波（mmWave）无线通信的关键组成部分。攻击者还可以方便地操纵 RIS 来实现恶意目的，例如获得窃听优势、降低无线链路质量或毒害信道估计。这些攻击将严重影响下一代通信系统的可用性、完整性和安全性。由于攻击者可能会改变物理层的射频传播环境，因此数据层的传统数据加密或身份验证机制没有用处，为了击败这些攻击，该项目将在物理层开展四个紧密相连的研究重点：（i。 ) 研究并创建 RIS 信号水印嵌入和签名附加，以实现高效、稳健的 RIS 信号/传播路径身份验证，(ii) 通过频谱执行的协作感知来定位恶意 RIS，(iii) 利用基于神经网络的波束成形用于低拦截概率和弹性 RIS 辅助通信，以及 (iv) 构建毫米波测试台，包括制造 RIS 并进行实验评估。该项目的新颖之处在于创建物理层安全构建块来保护 RIS。辅助毫米波通信的更广泛意义和重要性是：(i) 为 RIS 辅助通信奠定安全基础，(ii) 确保不同频段和范式中的射频通信，包括反向散射和共生通信， (iii) 为 Next G Alliance 的路线图和标准化工作做出贡献，以及 (iv) 通过参与大学提供的各种实习和外展计划扩大代表性不足群体的参与。该奖项的法定使命是通过以下方式获得支持：使用基金会的智力价值和更广泛的影响审查标准进行评估。
