II-NEW: An Infrastructure for Researching Wireless Link Signatures

该项目的目标是获取和建立一个无线测量基础设施，并使用它来研究新的无线链路签名及其应用。无线发送器和接收器之间的无线链路的签名表示无线链路的独特物理特性。无线链路签名应用包括在无线发送器和接收器之间建立秘密密钥，而无需通信秘密密钥，以及位置区分，即当发送器改变其位置时检测一个或多个接收器的能力。本研究的智力价值包括：(i)在(a)异质室内和室外环境下广泛测量无线链路特性，(b)不同类型发射器的各种无线标准，以及(c)借助高性能频谱分析仪的不同频段，（ii）开发不同无线链路签名应用的新方法，包括位置区分和密钥建立。使用这些度量，以及（iii）通过实施对方法进行评估。该研究对基于无线链路签名的应用的开发和部署具有重要影响。它还提供了大量的测量数据，有助于了解独特的无线链路特性，以及传统的无线链路性能建模和评估。这项研究活动通过网络和安全课程中新的测量和推理项目整合到教育课程中。此外，本研究与现有的NSF STEP高中外展项目结合使用。

The objective of this project is to acquire and set up a wireless measurement infrastructure and use it to research new wireless link signatures and their applications. The signature of a wireless link between a wireless transmitter and a receiver represents the wireless link's unique physical characteristics. Wireless link signature applications include secret key establishment between a wireless transmitter and a receiver without ever communicating the secret key, and location distinction which is the ability to detect at one or more receivers when a transmitter changes its location.The intellectual merit of this research includes (i) extensive measurements of wireless link characteristics under (a) heterogeneous indoor and outdoor settings, (b) a variety of wireless standards with different types of transmitters, and (c) different frequency bands with the help of highly capable spectrum analyzers, (ii) development of novel methodologies for different wireless link signature applications including location distinction, and secret key establishment, using these measurements, and (iii) evaluation of the methodologies through implementation.This research impacts the development and deployment of wireless link signature-based applications. It also contributes a vast amount of measurement data that is useful for understanding unique wireless link characteristics, and also traditional wireless link performance modeling and evaluation. This research activity is integrated in the education curriculum through new measurement and inference projects in the networking and security classes. Furthermore, this research is used in conjunction with an existing NSF STEP project for high school outreach.
