Simultaneously Exposing and Jamming Covert Communications via Disco Reconfigurable Intelligent Surfaces
Huan Huang, Hongliang Zhang, Yi Cai +3
Covert communications provide a stronger privacy protection than cryptography and physical-layer security (PLS). However, previous works on covert communications have implicitly as…
Disco Intelligent Omni-Surfaces: 360-degree Fully-Passive Jamming Attacks
Huan Huang, Hongliang Zhang, Jide Yuan +6
Intelligent omni-surfaces (IOSs) with 360-degree electromagnetic radiation significantly improves the performance of wireless systems, while an adversarial IOS also poses a signifi…
RIS-Aided Dual-Polarized MIMO: How Large a Surface is Needed to Beat Single Polarization?
Zizhou Zheng, Huan Huang, Hongliang Zhang +1
Dual-polarized (DP) multiple-input-multiple-output (MIMO) systems have been widely adopted in commercial mobile wireless communications. Such systems achieve multiplexing and diver…
Integrated Sensing and Communication Under DISCO Physical-Layer Jamming Attacks
Huan Huang, Hongliang Zhang, Weidong Mei +4
Integrated sensing and communication (ISAC) systems traditionally presuppose that sensing and communication (S&C) channels remain approximately constant during their coherence time…
IRS-Enhanced Anti-Jamming Precoding Against DISCO Physical Layer Jamming Attacks
Huan Huang, Hongliang Zhang, Yi Cai +3
Illegitimate intelligent reflective surfaces (IRSs) can pose significant physical layer security risks on multi-user multiple-input single-output (MU-MISO) systems. Recently, a DIS…
DISCO Might Not Be Funky: Random Intelligent Reflective Surface Configurations That Attack
Huan Huang, Lipeng Dai, Hongliang Zhang +5
Emerging intelligent reflective surfaces (IRSs) significantly improve system performance, but also pose a significant risk for physical layer security (PLS). Unlike the extensive r…
