AbstractThe objective of this research is to develop a localization system capable of localizing an adversary that is actively trying to disguise its location in a wireless network by distorting its signal features. The approach is a proactive, cross-layer localization design that incorporates attack traceback, cross-layer traffic manipulation, and physical layer position estimation. The attack traceback aspect focuses on narrowing down an adversary?s location to the coverage area of a couple of access points. The traffic manipulation aspect will develop trapping techniques to force or lure the adversary to exhibit their true location-related signal features. Leveraging these true location-related signal features, the physical layer position estimation aspect will develop proactive and robust localization techniques to accurately position the adversary.Intellectual Merit: The proposed project will help to establish accountability in wireless networks and will result in the development of key attack countermeasures. It is the first to address many technical challenges in localization and traceback. This project can also enhance the security of systems where location information is used to restrict access to critical resources. Furthermore, the proposed research results can be used to improve the accuracy of localization systems in harsh communication environments that severely distort the characteristics of emitted signals from legitimate users. Broader Impact: The proposed research will foster the integration of research and education by fortifying the existing curriculum with the project?s research results. The outreach component of the project will disseminate research results and pedagogical materials via education and industry outreach programs.

摘要这项研究的目的是开发一个本地化系统，能够将对手定位，该系统正在试图通过扭曲信号特征来积极地试图掩盖其在无线网络中的位置。该方法是一种积极主动的跨层定位设计，它结合了攻击追溯，跨层交通操纵和物理层位置估计。攻击追溯方面的重点是将对手的位置缩小到几个接入点的覆盖范围。交通操纵方面将开发诱捕技术，以强迫或引诱对手以表现出其真正的位置相关信号特征。利用这些真正与位置相关的信号特征，物理层位置估计方面将发展为积极且可靠的定位技术，以准确定位对手。智能优点：拟议的项目将有助于在无线网络中建立问责制，并将导致关键攻击对策的发展。 这是第一个解决本地化和追溯方面许多技术挑战的问题。 该项目还可以增强位置信息用于限制对关键资源的访问的系统安全性。此外，提出的研究结果可用于提高严峻的通信环境中本地化系统的准确性，从而严重扭曲了合法用户的发射信号的特征。更广泛的影响：拟议的研究将通过将现有课程与项目的研究结果加固，从而促进研究和教育的整合。该项目的外展部分将通过教育和行业推广计划传播研究结果和教学材料。
