Abstract
Due to device-specific defects introduced during the hardware manufacturing process, the radio frequency fingerprint (RFF) can be extracted to identify wireless devices and further avoid spoofing attacks. Many effective RFF identification methods have been proposed based on either machine learning or deep learning. However, from the perspective of communication security, if the RFF of the transmitter can be easily extracted and identified, attackers can disguise themselves as legitimate transmitters by impersonating RFF and other means, thereby undermining the security of wireless communications. Therefore, concealing the RFF of legitimate transmitters from detection and camouflage attacks has become a highly challenging issue in the field of wireless communications. This article presents an active RFF concealment (RFFC) method, which removes the nonlinear features of the transmitter system, thereby preventing attackers from obtaining the transmitter's RFF and ensuring the identity security of the transmitter. To evaluate the performance of RFF concealing technology, we simulate seven types of RFFC systems, and collect datasets without and with RFFC technology. The simulation results show that the performance of traditional transmitter identification methods decreases sharply after RFFC. Especially in low signal-to-noise ratio environments and complex multipath channel conditions, the proposed RFFC technology makes the RFF features chaotic and difficult to detect, leading to dramatically reduced effectiveness of existing transmitter identification methods.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
