Abstract

This study investigates physical layer authentication (PLA) in the downlink of massive MIMO systems. It is demonstrated that a multi-antenna rogue base station (BS) can impersonate the legitimate BS by injecting malicious signals during downlink transmission. Exploiting channel hardening, three PLA schemes are proposed, which are based on the large-scale fading coefficient and incorporate channel correlation for practical implementation. The false alarm and detection probabilities are analyzed. Additionally, a dual-threshold strategy for authentication decisions is developed. Finally, numerical simulations are conducted to validate the proposed schemes, elucidating the impact of system parameters on authentication accuracy.

本研究探讨了大规模多输入多输出（MIMO）系统下行链路中的物理层验证（PLA）。研究表明，多天线流氓基站（BS）可以通过在下行链路传输过程中注入恶意信号来冒充合法基站。利用信道加固，提出了三种 PLA 方案，这些方案基于大规模衰落系数，并结合了信道相关性以实现实际应用。分析了误报和检测概率。此外，还开发了一种用于验证决策的双阈值策略。最后，通过数值模拟验证了所提出的方案，阐明了系统参数对认证准确性的影响。
