CT-OpenMax: A Novel Open-Set WiFi RF Fingerprinting Method via Center Constrained Learning and Confidence-Guided Tail Modeling
Yuanyu Zhang, Junjie Yang, Ji He +3
Radio frequency fingerprinting (RFF) enables device authentication from transmitter-specific hardware imperfections, but practical deployment requires cross-environment open-set re…
MARL-Based Sequential RIS Auctions: A Physical-Layer Security Analysis
Yuanyu Zhang, Yu Zhang, Jialu He +3
Reconfigurable intelligent surfaces (RISs) hold great potential to enhance coverage, spectral efficiency, and communication security by intelligently configuring their reflecting e…
IriSig-Spoof: A Real-World Benchmark for Time-Robust Satellite RF Fingerprinting and Spoofing Detection
Shichang Guo, Yuanyu Zhang, Shuangrui Zhao +3
Low Earth orbit (LEO) satellite Internet is becoming critical communications infrastructure, yet its open wireless links remain vulnerable to satellite impersonation and signal spo…
On a General Theoretical Framework for Radio Frequency Fingerprint-Based Authentication
Yuanyu Zhang, Jianing Wang, Shuangrui Zhao +3
While radio frequency fingerprint (RFF)-based wireless device authentication has been widely studied across different datasets and scenarios, there still lacks a fundamental theory…
GalSAS-SDR-SIM: An End-to-End Simulation Platform for Galileo Signal Authentication Service
Haiyang Wang, Yuanyu Zhang, Wensen Du +3
