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…
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…
