摘要

本研究探讨了可重构智能表面（RIS）辅助无线网络在目的地存在多个干扰器的情况下的保密性能。特别是，研究了安全 RIS 辅助网络设计中的三个关键问题：干扰者的影响、多个窃听者（共谋和非共谋）的操作以及 RIS 的益处。为了研究它们的影响，以封闭形式推导出了保密中断概率的分析表达式。此外，还提供了高信噪比（SNR）条件下的渐近分析。最后，通过数值模拟验证了分析结果。

Effects of co-channel interference on RIS empowered wireless networks amid multiple eavesdropping attempts

In this study, the secrecy performance of reconfigurable intelligent surfaces (RIS)-aided wireless networks in the existence of multiple interferers towards the destination is investigated. In particular, three critical issues in the design of secure RIS-assisted networks are examined: effects of interferers, operation of multiple eavesdroppers (colluding and non-colluding), and benefit of RISs. To examine their effects, the analytical expressions of secrecy outage probability are derived in a closed form. Additionally, asymptotic analyses at a high signal-to-noise ratio (SNR) regime are provided. Finally, the analytical results are validated through numerical simulations.
