AI 中文摘要
尽管基于射频指纹（RFF）的无线设备认证已在不同数据集和场景中得到广泛研究，但仍缺乏基础理论解释RFF为何以及如何作为可靠的设备标识，这严重阻碍了该认证技术的实际应用。本文将RFF建模与认证属性分析相结合，提出通用理论框架以推动该理论的发展。RFF建模过程揭示了RFF如何沿发射机-信道-接收机链产生、演化和被观测；在此基础上，认证属性分析过程概述了应如何从唯一性、稳定性、可区分性和不可伪造性四个方面检验RFF的可信度。通过将RFF的形成/演化与这些认证属性关联，该框架为理解基于RFF的认证在实践中为何以及如何可信提供了坚实基础。本文还基于所提框架的理论见解，探讨了通信-认证协同设计问题。
英文摘要
While radio frequency fingerprint (RFF)-based wireless device authentication has been widely studied across different datasets and scenarios, there still lacks a fundamental theory to explain why and how RFF can serve as a reliable device identity, significantly hindering the practical application of such an authentication technology. In this article, we integrate the RFF modeling with authentication property analysis to propose a general theoretical framework to facilitate the development of such a theory. The RFF modeling process reveals how RFFs are induced, evolved and observed along the transmitter-channel-receiver chain, built upon which, the authentication property analysis process then outlines how the trustworthiness of an RFF should be examined in terms of its uniqueness, stability, distinguishability, and unforgeability. By linking the RFF formation/evolution to these authentication properties, the framework offers a solid foundation for understanding why and how RFF-based authentication is trustworthy in practice. We also discuss the communication-authentication co-design issue based on the theoretical insights from the proposed framework.
