Many of today's wireless devices feature small-scale, low-cost designs to align with the requirements of Internet of Things systems and applications. Thus, many of these devices cannot perform cryptographic operations or need to avoid such operations to preserve energy (e.g., implantable medical devices). However, these devices commonly handle sensitive data. An important research direction is to create efficient, lightweight yet secure designs of such devices by leveraging unique wireless channel properties in wireless networks while considering formal adversary models. In this project, this challenge is tackled via an adversary-driven approach to improve wireless network security. The project's novelties are: (i) creating stronger, practical adversary models to understand the limitations of today's security designs of IoT systems leveraging the wireless channel properties and (ii) designing new defense strategies to further advance the state-of-the-art wireless network security designs. The project's broader significance and importance are advancing the state-of-the-art in network security, including undergraduate student training opportunities, openly disseminated training materials, and conducting outreach activities.This project creates new adversary-driven approaches targeting the three design aspects in existing studies: (i) leveraging the channel state information as a unique network profile, (ii) establishing a secret from the wireless channel, and (iii) hiding a secret using the wireless channel. Specifically, the project encompasses three research thrusts based on both system designs and practical evaluations: (i) creating new attacks against channel state information-based user or location profiling/verification and designing network countermeasures; (ii) formulating new adversary models and designing frameworks for wireless secret key establishment, and (iii) proposing new adversary-driven secure information exchange frameworks using the wireless channel. The project involves comprehensive evaluations based on real-world wireless experiments to validate and improve the proposed designs.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.

当今的许多无线设备采用小规模的低成本设计，可与物联网系统和应用程序的要求保持一致。因此，这些设备中的许多无法执行加密操作，也无法避免使用此类操作以保持能量（例如，可植入的医疗设备）。但是，这些设备通常处理敏感数据。一个重要的研究方向是通过利用无线网络中的独特无线通道属性，同时考虑正式的对手模型，从而创建高效，轻巧但安全的设计。在这个项目中，通过对手驱动的方法来提高无线网络安全性来应对这一挑战。该项目的新颖性是：（i）创建更强大，实用的对手模型，以了解利用无线通道属性的当今物联网系统安全设计的局限性，并（ii）设计新的防御策略，以进一步推进最先进的无线网络安全设计。该项目在网络安全方面的最新意义和重要性正在推进最新的网络安全性，包括学生培训机会，公开传播培训材料并进行外展活动。该项目创建了针对现有研究中三个设计方面的新的对手驱动的方法：（i）使用频道作为独特的网络概况，（ii）建立了nirs（ii），（ii）秘书，（ii）秘书，II（ii）和II（ii）和II（ii），并且是II（II）。具体而言，该项目涵盖了基于系统设计和实际评估的三个研究推力：（i）对基于渠道的信息的用户或位置分析/验证/验证和设计网络对策进行新的攻击； （ii）为无线秘密密钥建立制定新的对手模型和设计框架，以及（iii）使用无线通道提出新的对手驱动的安全信息交换框架。该项目涉及基于现实世界无线实验的全面评估，以验证和改进拟议的设计。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智力优点和更广泛的影响评估的评估来支持的。
