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.

AbstractThe本研究的目的是开发一种定位系统，能够定位的对手，是积极试图掩盖其位置在无线网络中通过扭曲其信号特征。该方法是一种主动的跨层本地化设计，结合了攻击追溯、跨层流量操纵和物理层位置估计。攻击追溯方面的重点是缩小对手？的位置到几个接入点的覆盖区域。交通操纵方面将开发诱捕技术，以迫使或引诱对手展示其真实的位置相关信号特征。利用这些真正的位置相关的信号功能，物理层位置估计方面将开发积极和强大的定位技术，以准确定位advertiser.Intellectual优点：拟议的项目将有助于建立问责制的无线网络，并将导致在关键的攻击对策的发展。 它是第一个解决本地化和追溯方面的许多技术挑战的工具。 该项目还可以加强使用位置信息限制访问关键资源的系统的安全性。此外，所提出的研究结果可用于提高定位系统的准确性，在恶劣的通信环境中，严重扭曲的合法用户的发射信号的特性。更广泛的影响：拟议的研究将促进研究和教育的整合，通过加强现有的课程与项目？的研究成果。该项目的外联部分将通过教育和行业外联方案传播研究成果和教学材料。
