Wireless communication infrastructure is poised to make a significant impact beyond cellular networks, such as in emerging internet-of-things (IoT) networks, device-to-device communications, and autonomous systems. Such systems may not have the full-fledged infrastructure or capabilities to achieve confidentiality via traditional cryptographic approaches. Furthermore, the broadcast nature of the wireless transmission medium can make them prone to information leakage through eavesdropping. This project develops new approaches to achieve provable wireless security in the presence of uncertainty about the wireless channel. The results of this project can have a wide reaching societal impact through mechanisms that can enable light-weight, and provably secure communication over the physical layer, and contribute to trustworthy operation of wireless infrastructure for various emerging applications. In addition to the research impact, the project will have an educational impact through curriculum development and the training of undergraduate and graduate students, in addition to outreach activities through the University of Arizona Science, Engineering and Mathematics (ASEM) scholars program and the STEM learning center.Over the last decade, several significant and fascinating insights have emerged on how to leverage knowledge of wireless channels to achieve secrecy. Despite these advances, the practical viability of physical layer security faces obstacles, primarily due to the fact that channel knowledge is available imperfectly, and is almost always unavailable from adversarial entities. This project will lay the foundations for achieving secrecy in scenarios where the precise knowledge about the wireless channel is minimal or non-existent. The key underpinnings behind making wireless security robust to channel knowledge uncertainty are argued to be rooted in the fundamental properties of wireless channels: path loss, fading, and inter-symbol interference. Instead of viewing these as negative attributes of the wireless channel, this project will devise approaches that systematically leverage statistical heterogeneity in these properties to gain advantage against external adversaries, even without the precise knowledge of the wireless channel. In particular, the specific goals of the project are: (i) to leverage heterogeneity of inter-symbol interference to achieve secrecy with only statistical knowledge about the channel; (ii) to develop principled encoding/decoding mechanisms that guarantee secrecy with only topological knowledge about the network; (iii) to generalize these concepts to large-scale single-hop and multi-hop networks with untrusted nodes; and (iv) to obtain information-theoretic bounds on the corresponding secrecy capacities for the various models with statistical channel knowledge.

无线通信基础设施有望在蜂窝网络之外产生重大影响，例如新兴的物联网（IoT）网络、设备到设备通信和自主系统。这种系统可能不具备通过传统加密方法实现保密性的成熟基础设施或能力。此外，无线传输介质的广播性质可能使它们易于通过窃听而泄露信息。该项目开发了新的方法，以实现可证明的无线安全的无线信道的不确定性的存在。该项目的结果可以通过实现物理层上的轻量级和可证明安全的通信的机制产生广泛的社会影响，并有助于各种新兴应用的无线基础设施的可靠运行。除了研究影响外，该项目还将通过课程开发和本科生和研究生的培训产生教育影响，此外还将通过亚利桑那大学科学，工程和数学（ASEM）学者计划和STEM学习中心开展外联活动。关于如何利用无线信道的知识来实现保密性，已经出现了几个重要的和令人着迷的见解。尽管有这些进步，物理层安全的实际可行性面临着障碍，主要是由于信道知识不完全可用，并且几乎总是无法从敌对实体获得。该项目将为在对无线信道的精确知识很少或不存在的情况下实现保密奠定基础。无线安全对信道知识不确定性的鲁棒性背后的关键基础被认为是植根于无线信道的基本属性：路径损耗，衰落和符号间干扰。而不是将这些视为无线信道的负面属性，该项目将设计方法，系统地利用这些属性的统计异质性，以获得对外部对手的优势，即使没有无线信道的精确知识。特别是，该项目的具体目标是：（i）利用符号间干扰的异质性，以实现保密与唯一的统计知识的信道;（ii）开发原则性的编码/解码机制，保证保密与唯一的拓扑知识的网络;（iii）将这些概念推广到大规模的单跳和多跳网络与不可信的节点;以及（iv）利用统计信道知识获得各种模型的相应保密容量的信息理论界。
