Holographic Beamforming for Semantic Communication
Shuhao Zeng, Haobo Zhang, Su Wang +5
Holographic beamforming enabled by metamaterial antennas has been proposed to facilitate spatial multiplexing at low hardware cost and low power consumption. However, existing holo…
Embodied AI in 6G Networks: From Intelligent Connectivity to Physical Intelligence
Junaid Sajid, Sheikh Salman Hassan, Wenshuai Liu +7
Embodied artificial intelligence (AI) couples perception and learned decision making to actions that change the physical world. This coupling distinguishes an embodied agent from a…
Road Network-Aware Personalized Trajectory Protection with Differential Privacy under Spatiotemporal Correlations
Minghui Min, Jiahui Liu, Mingge Cao +4
Location-Based Services (LBSs) offer significant convenience to mobile users but pose significant privacy risks, as attackers can infer sensitive personal information through spati…
Personalized 3D Spatiotemporal Trajectory Privacy Protection with Differential and Distortion Geo-Perturbation
Minghui Min, Yulu Li, Gang Li +4
The rapid advancement of location-based services (LBSs) in three-dimensional (3D) domains, such as smart cities and intelligent transportation, has raised concerns over 3D spatiote…
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…
Reconfigurable Holographic Surface: A New Paradigm for Ultra-Massive MIMO
Boya Di, Hongliang Zhang, Rui Zhang +2
Evolving from massive multiple-input multiple-output (MIMO) in current 5G communications, ultra-massive MIMO emerges as a seminal technology for fulfilling more stringent requireme…
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…
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…
Protecting Personalized Trajectory with Differential Privacy under Temporal Correlations
Mingge Cao, Haopeng Zhu, Minghui Min +4
Location-based services (LBSs) in vehicular ad hoc networks (VANETs) offer users numerous conveniences. However, the extensive use of LBSs raises concerns about the privacy of user…
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…
