标题： OFDM-based JCAS under Attack: The Dual Threat of Spoofing and Jamming in WLAN Sensing

摘要： 本研究揭示了联合通信和传感（JCAS）范围内的无线局域网（WLAN）感知的漏洞，重点关注目标欺骗和欺骗性干扰技术。 我们使用正交频分复用（OFDM）来探讨对手如何利用WLAN的感知能力注入虚假目标并扰乱正常操作。 与传统方法需要复杂的数字射频存储硬件不同，我们证明了更简单的软件定义无线电可以在WLAN环境中有效地充当欺骗性干扰器。 通过全面建模和实际实验，我们展示了欺骗性干扰器如何通过改变信号完整性来操纵距离-多普勒图（RDM），从而对基于OFDM的JCAS系统构成重大安全威胁。 我们的研究全面评估了干扰器对RDM的影响，并提出了几种复杂性和可检测性不同的干扰策略。 显示英文摘要

摘要： This study reveals the vulnerabilities of Wireless Local Area Networks (WLAN) sensing, under the scope of joint communication and sensing (JCAS), focusing on target spoofing and deceptive jamming techniques. We use orthogonal frequency-division multiplexing (OFDM) to explore how adversaries can exploit WLAN's sensing capabilities to inject false targets and disrupt normal operations. Unlike traditional methods that require sophisticated digital radio-frequency memory hardware, we demonstrate that much simpler software-defined radios can effectively serve as deceptive jammers in WLAN settings. Through comprehensive modeling and practical experiments, we show how deceptive jammers can manipulate the range-Doppler map (RDM) by altering signal integrity, thereby posing significant security threats to OFDM-based JCAS systems. Our findings comprehensively evaluate jammer impact on RDMs and propose several jamming strategies that vary in complexity and detectability.
