摘要

在这封信中，我们研究了流体天线系统(FAS)-可重构智能表面（RIS）通信系统的安全性。基站（BS）采用单一的固定位置天线，而合法的接收器和窃听者都配备了流动天线。利用块相关模型和中心极限定理，导出了平均保密容量和保密中断概率（SOP）的近似表达式。仿真结果验证了我们的分析，证明了块相关模型在准确评估安全性能方面的有效性。此外，仿真结果表明，FAS-RIS系统在安全性方面明显优于其他系统，进一步强调了其在安全通信应用中的潜力。

Unlocking FAS-RIS Security Analysis With Block-Correlation Model

In this letter, we investigate the security of fluid antenna system (FAS)-reconfigurable intelligent surfaces (RIS) communication systems. The base station (BS) employs a single fixed-position antenna, while both the legitimate receiver and the eavesdropper are equipped with fluid antennas. By utilizing the block-correlation model and the central limit theorem (CLT), we derive approximate expressions for the average secrecy capacity and secrecy outage probability (SOP). Our analysis, validated by simulation results, demonstrates the effectiveness of the block-correlation model in accurately assessing the security performance. Moreover, simulation results reveal that FAS-RIS system significantly outperforms other systems in terms of security, further underscoring its potential in secure communication applications.
