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就变得不相关。这一特性丰富了一个新兴的研究领域，该领域利用无线信道特征来验证无线发射机。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是位置识别技术的安全基础，它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特性的认证和位置区分方案很流行，但本研究发现了对这些方案的重要攻击。具体地说，攻击者可以通过创建与真实无线通道类似的人工无线通道，轻松绕过身份验证或伪装位置更改。基于未披露的攻击，该项目将专注于两个重要的研究方向：(I)它将研究使接收器能够有效地检测该攻击的存在的方法；(Ii)另一方面，它还将探索人工无线信道的创建如何为密钥建立和匿名通信等无线安全技术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认证和位置区分方法的安全性，并因此由于这些方法在无线系统设计中的广泛采用而影响无线安全研究。该项目还创造了一个新的研究方向，即创建人造无线通道来解决实际的无线安全问题。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员。
