The use of frequencies above 100 GHz for wireless communication is rapidly emerging as a key enabler for future (beyond 5G) wireless systems. These high-frequency systems, which are referred to as terahertz (THz) links, offer numerous exciting possibilities, such as ultra-high-speed data transmission and enhanced resilience against malicious attacks such as eavesdropping. Yet, so far, little research has been devoted to the question of how to implement a network that can provide high bandwidth links for multiple mobile users, while still maintaining security against eavesdroppers. The objective of this proposal is to develop the hardware and protocols necessary to implement a secure network for mobile users which efficiently exploits these high frequencies. The research team will develop a set of methodologies to enable a base station to rapidly locate multiple users in a broadcast region (even if they are moving), to establish high-speed wireless links with each of them, and to detect and mitigate eavesdropping attacks. In addition, the project includes a coordinated plan for broadening participation of traditionallyunder-represented groups, and includes a one-week summer course on THz research for high-school students.The overarching goal of this project is to develop a radically new node architecture which can intrinsically support multiple access for mobile clients in a broadband THz network, while also maintaining a high degree of security. One thrust of this project involves the exploration of novel antenna designs which exploit strong angular dispersion. We propose a new method to enable active fast electrical tuning of such devices which will be exploited for detection of an eavesdropping attack, as well as for localization of legitimate users and mobility detection. A second project thrust aims to develop spatio-temporal modulated array architectures for scrambling the information contained in side-lobes of the broadcast, via spectral aliasing. Combined with agile sensing functionalities, the proposed interface will selectively create secure zones for communication. In a third thrust, we will leverage the power of this new node architecture to ensure that the quality of service for multiple mobile users is maintained, even while guaranteeing that eavesdroppers are unable to access, not only the primary communication channels, but also control plane functions required to establish and maintain mobile links. The result will provide the optimal performance for a spectrally efficient and secure THz network, even in the presence of a sophisticated attack by colluding eavesdroppers.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.

在100 GHz以上的无线通信中使用频率正在迅速成为未来（超过5G）无线系统的关键推动力。这些被称为Terahertz（THZ）链接的高频系统提供了许多令人兴奋的可能性，例如超高速度数据传输和对恶意攻击（例如窃听）的弹性增强。然而，到目前为止，很少有研究专门研究如何实现可以为多个移动用户提供高带宽链接的网络，同时仍保持针对EavesDroppers的安全性。该建议的目的是开发为有效利用这些高频的移动用户实现安全网络所需的硬件和协议。研究团队将开发一组方法，以使基站能够在广播区域快速找到多个用户（即使他们正在移动），与每个人建立高速无线链接，并检测和减轻窃听攻击。此外，该项目还包括一个协调的计划，以扩大传统代表性的群体的参与，并包括为高中生的THZ研究进行的为期一周的夏季课程。该项目的总体目标是开发一个毫无疑问的新节点体系结构，可以在宽带THZ网络中本质上支持为移动客户提供多重访问，同时还可以维持高度的安全性。该项目的一个推力涉及探索利用强角分散的新型天线设计。我们提出了一种新方法，以实现此类设备的积极快速电气调整，这些设备将被利用，以检测窃听攻击，以及合法用户的定位和移动性检测。第二个项目的推力旨在开发时空调制阵列体系结构，以通过频谱混叠来拼写广播侧齿轮中包含的信息。结合敏捷感测功能，提出的接口将选择性地创建安全区域进行通信。在第三个推力中，我们将利用这种新节点体系结构的功能来确保维持多个移动用户的服务质量，即使在确保窃听者无法访问的同时，不仅是主要的通信渠道，而且还需要控制平面功能来建立和维护移动链接。该结果将为频谱高效且安全的THZ网络提供最佳性能，即使在碰撞窃听者进行复杂的攻击的情况下，该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来进行评估的。
