Cyclic-Prefix OFDM Probing for Spatial-ISI-Free Distributed Acoustic Sensing via Frequency-Domain Channel Reconstruction
Huan Huang, Zhiyang Xue, Ziang Chen +4
Nonzero sidelobes in matched-filter pulse-compression distributed acoustic sensing (DAS) cause deterministic inter-range-bin leakage, termed spatial inter-symbol interference (ISI)…
Unsupervised Semi-Parametric Plug-in Likelihood-Ratio Detection for Covert Communications in the Presence of Disco Reconfigurable Intelligent Surfaces
Luyao Sun, Huan Huang, Yongxing Song +5
Covert communications, also referred to as low probability of detection (LPD) communications, provide a higher level of privacy protection than cryptography and physical-layer secu…
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…
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…
Anti-Jamming Precoding Against Disco Intelligent Reflecting Surfaces Based Fully-Passive Jamming Attacks
Huan Huang, Lipeng Dai, Hongliang Zhang +5
Emerging intelligent reflecting surfaces (IRSs) significantly improve system performance, but also pose a huge risk for physical layer security. Existing works have illustrated tha…
An Anti-Jamming Strategy for Disco Intelligent Reflecting Surfaces Based Fully-Passive Jamming Attacks
Huan Huang, Hongliang Zhang, Yi Cai +2
Emerging intelligent reflecting surfaces (IRSs) significantly improve system performance, while also pose a huge risk for physical layer security. A disco IRS (DIRS), i.e., an ille…
Disco Intelligent Reflecting Surfaces: Active Channel Aging for Fully-Passive Jamming Attacks
Huan Huang, Ying Zhang, Hongliang Zhang +3
Due to the open communications environment in wireless channels, wireless networks are vulnerable to jamming attacks. However, existing approaches for jamming rely on knowledge of…
