项目摘要

The needs of future networks beyond 5G and Internet of Things call for a comprehensive and inclusive approach to security. By harnessing the imperfections of communication channels, physical-layer security integrates security concerns into the design of communication systems with benefits such as energy efficiency and simplified key management; physical-layer security often imposes requirements, however, which has impeded its practical adoption and deployment. Furthermore, in some applications where physical-layer security is uniquely suitable and no obvious cryptographic solution exists, such as situations requiring covertness, results to date have been disappointing in terms of predicted data transmission speeds. This project addresses these two points. The outcomes of this project can ensure secure wireless communications in future networks with minimal performance impact. The first thrust of this project brings a new perspective to the study of cooperative security through the lens of information asymmetry against adversaries. This part of the project aims to elucidate how cooperation can provide knowledge to one user about the variations in the channel induced by the signaling of another in a manner that creates new and hitherto unforeseen advantages over an adversary. The second thrust of this project explores the benefits of information asymmetry for covert communications, including the role of channel state knowledge, which is foreseen as a key mechanism to not only circumvent the square-root law of covert communication but also to alleviat the need for a shared secret key. The impact of different-quality channel states being available at different nodes will be studied.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.

超越5G和物联网的未来网络的需求要求采用全面和包容的安全方法。通过利用通信渠道的缺陷，物理层安全性将安全问题集成到具有诸如能源效率和简化密钥管理等优点的通信系统的设计中；但是，物理层安全通常会施加要求，这阻碍了其实际采用和部署。此外，在某些物理层安全性非常合适并且没有明显的加密解决方案的应用中，例如需要隐蔽性的情况，迄今为止的结果在预测的数据传输速度方面令人失望。该项目解决了这两个点。该项目的结果可以确保在未来的网络中安全的无线通信，其性能影响最小。该项目的第一个主旨通过针对对手的信息不对称性镜头为研究合作安全带来了新的观点。该项目的这一部分旨在阐明合作如何向一个用户提供知识，以了解另一个通过另一个人的信号传导引起的渠道变化，从而创造出与对手相对于对手的新且迄今无法预料的优势。该项目的第二个力量探讨了信息不对称性的秘密通信的好处，包括渠道状态知识的作用，渠道状态知识的作用是预见的，这是一种关键机制，不仅可以规避隐秘沟通的正方形 - 根源法律，还可以减轻对共享秘密密钥的需求。将研究在不同节点上可用的不同质量渠道国家的影响。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
