Electromagnetic fingerprint; physical layer authentication; radiation source recognition; feature extraction.Abstract
This paper conducts research on key technologies in the fields of radiation source identification and physical layer certification, and deeply analyzes its core difficulties in low reliability, environmental interference resistance, feature drift, cross-device compatibility, privacy protection, etc. By comparing the technical routes, performance indicators, applicable scenarios and constraints of domestic and foreign research teams, we clarify technical bottlenecks and industrial application obstacles, and finally sort out the future evolution direction to provide support for the practical development of electromagnetic fingerprint technology.
