A Survey of Physical-layer Authentication Enhanced by Emerging Spatial Domain Technologies
Yuhao Chen, Boxiang He, Junshan Luo +7
This article surveys spatial-domain-enhanced Physical-layer Authentication (PLA), with Dual-polarized Antennas (DPA), Massive Multiple-Input Multiple-Output (MIMO), and Reconfigura…
Cross-channel Specific Emitter Identification and Verification via Signal Envelope
Yuhao Chen, Boxiang He, Shilian Wang +1
Specific emitter identification (SEI) determines which known emitter a received signal originates from, while specific emitter verification (SEV) determines whether the received si…
Tag-based Physical-Layer Authentication Against Message Interference
Lei Yao, Boxiang He, Shilian Wang +2
Tag-based Physical-Layer Authentication (PLA) has attracted significant attention in recent years due to its low complexity, high security, and low latency. Traditional tag-based P…
Frozen-Tag-Based Physical-Layer Authentication Against User Interference
Lei Yao, Boxiang He, Shilian Wang +1
Tag-based physical layer authentication (PLA) has garnered significant attention due to its low complexity and enhanced security. However, existing PLA schemes encounter two challe…
Specific Multi-emitter Identification: Theoretical Limits and Low-complexity Design
Yuhao Chen, Boxiang He, Junshan Luo +3
Specific emitter identification (SEI) distinguishes emitters by utilizing hardware-induced signal imperfections. However, conventional SEI techniques are primarily designed for sin…
Specific multi-emitter identification via multi-label learning
Yuhao Chen, Boxiang He, Shilian Wang +1
Specific emitter identification leverages hardware-induced impairments to uniquely determine a specific transmitter. However, existing approaches fail to address scenarios where si…
