论文摘要
RIS是标志着下一代无线的重大技术进步之一。 RIS技术还开辟了新的安全威胁的可能性，因为撞击信号的反射可用于恶意目的。本文介绍了RIS辅助攻击的基本概念，该攻击将合法信号重新引起了恶意目标。从这种基本情况中确定了特定的攻击，并选择了RIS辅助的信号取消攻击作为评估作为一种固有利用RIS功能的攻击。评估的关键要点是，有效的攻击需要准确的渠道信息，即在有利的位置部署的RI（从攻击者的角度来看），并且对已经遭受路径损失减少的合法链接产生了不成比例的影响。这些观察促进了未来工作的特定安全解决方案和建议。
RIS is one of the significant technological advancements that will mark next-generation wireless. RIS technology also opens up the possibility of new security threats, since the reflection of impinging signals can be used for malicious purposes. This article introduces the basic concept for a RIS-assisted attack that re-uses the legitimate signal towards a malicious objective. Specific attacks are identified from this base scenario, and the RIS-assisted signal cancellation attack is selected for evaluation as an attack that inherently exploits RIS capabilities. The key takeaway from the evaluation is that an effective attack requires accurate channel information, a RIS deployed in a favorable location (from the point of view of the attacker), and it disproportionately affects legitimate links that already suffer from reduced path loss. These observations motivate specific security solutions and recommendations for future work.
