论文摘要
物理层安全性是一种有前途的方法，可以使传统的加密方法受益。物理层安全性的想法是利用传播介质的特征及其损害，以确保在物理层中的安全通信。这项工作介绍了对用于衡量物理层安全性的保密性能的主要信息理论指标的全面综述。此外，还提供了与最常用的物理层安全技术相关的理论框架，以提高保密性能。最后，我们的工作对几种启用5G技术的物理层安全性研究进行了调查，例如大量多输入多输出，毫米波通信，异质网络，非官方多重访问和全双工。此外，我们包括上述技术的关键概念。还确定了物理层安全性的研究和技术挑战的未来领域。
Physical layer security is a promising approach that can benefit traditional encryption methods. The idea of physical layer security is to take advantage of the features of the propagation medium and its impairments to ensure secure communication in the physical layer. This work introduces a comprehensive review of the main information-theoretic metrics used to measure the secrecy performance in physical layer security. Furthermore, a theoretical framework related to the most commonly used physical layer security techniques to improve the secrecy performance is provided. Finally, our work surveys physical layer security research over several enabling 5G technologies, such as massive multiple-input multiple-output, millimeter-wave communications, heterogeneous networks, non-orthogonal multiple access, and full-duplex. Also, we include the key concepts of each of the aforementioned technologies. Future fields of research and technical challenges of physical layer security are also identified.
