Privacy Preserving Localization for UASNs via Adversarial Cryptography using Acoustic Channel Features
Bibliographic record
Abstract
In most existing underwater localization solutions, the risk of position information leakage persists, as anchor positions are revealed to the sensors performing position estimation. Conventional privacy protection methods designed for terrestrial networks often fail underwater due to the unique characteristics of the physical channels. Moreover, solutions proposed for the limited research on underwater privacy protection introduce expensive equipment costs and communication expenses. To tackle these challenges and reduce costs, this paper proposes a novel secure localization scheme tailored for underwater acoustic sensor networks (UASNs) based on adversarial neural cryptography utilizing acoustic channel features. The proposed scheme introduces an adversarial cryptography model to safeguard the transmission of legitimate localization data and dynamically counter eavesdroppers with learning capabilities in real-time. Furthermore, to obtain effective keys and minimize unnecessary key transmission, the scheme strategically employs channel features as cryptographic keys. Simulation results validate the effectiveness of this approach, demonstrating its ability to prevent the leakage of positional data, maintain localization precision, and operate with reduced hardware expenses and communication overhead compared to conventional methods.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
