Wireless channel exhibits the spatial uncorrelation property, i.e., the characteristic of a wireless channel becomes uncorrelated every half carrier wavelength over distance. This property fertilizes an emerging research area that utilizes wireless channel characteristics to authenticate a wireless transmitter. In addition to transmitter authentication, the spatial uncorrelation property of wireless channel has long served as the security foundation of location distinction techniques, which use changes in wireless channel characteristics to identify location changes of a wireless transmitter. Despite the prevalence of authentication and location distinction schemes based on the spatial uncorrelation property, this research identified an important attack against these schemes. Specifically, an attacker can easily bypass authentication or camouflage location changes by creating an artificial wireless channel similar to the real one. Based on the unrevealed attack, this project will focus on two important directions of research: (i) it will investigate methods that can enable a receiver to effectively detect the existence of this attack; and (ii) it will also explore how the creation of artificial wireless channels, on the other hand, paves the way for significant advancement in wireless security techniques, such as key establishment and anonymous communication. The project has the potential to substantially improve the security of existing channel based authentication and location distinction approaches, and accordingly impacts wireless security research due to the wide adoption of these approaches in the design of wireless systems. The project also creates a new research direction on creating artificial wireless channels to solve practical wireless security problems. All research results will be freely distributed. This research will be coupled with education and training for introducing students to wireless security research, as well as broadening security education to non-specialists.

无线信道表现出空间不相关特性，即无线信道的特性在距离上每半个载波波长变得不相关。这一特性催生了一个利用无线信道特性来验证无线发射机的新兴研究领域。除了发射机认证之外，无线信道的空间不相关特性长期以来一直作为位置区分技术的安全基础，该技术利用无线信道特性的变化来识别无线发射机的位置变化。尽管基于空间不相关性的身份验证和位置区分方案很流行，但这项研究发现了针对这些方案的重要攻击。具体来说，攻击者可以通过创建类似于真实无线通道的人工无线通道，轻松绕过身份验证或伪装位置更改。基于未揭露的攻击，该项目将重点关注两个重要的研究方向：（i）研究能够使接收者有效检测到这种攻击的存在的方法； (ii) 另一方面，它还将探讨人工无线信道的创建如何为无线安全技术（例如密钥建立和匿名通信）的重大进步铺平道路。该项目有可能大幅提高现有基于信道的身份验证和位置区分方法的安全性，并由于这些方法在无线系统设计中的广泛采用而相应地影响无线安全研究。该项目还开创了创建人工无线信道以解决实际无线安全问题的新研究方向。所有研究成果将免费分发。这项研究将与向学生介绍无线安全研究的教育和培训相结合，并将安全教育扩大到非专业人士。
