New research tackles physical-layer authentication for non-terrestrial networks · 2 sources

By PulseAugur Editorial · [2 sources] ·

Two new research papers propose advanced methods for physical-layer authentication (PLA) in non-terrestrial networks (NTNs), addressing challenges like eavesdropping and environmental variations. The first paper introduces SAFA-MZ, a scheme that embeds group-level authentication tags into a collaborative multi-layer rate-splitting multiple access (RSMA) transmission structure, utilizing artificial noise and group differential privacy to enhance security and spectral efficiency. The second paper presents SAFA-MZ as a causal meta-learning framework that combines multiple physical-layer features and uses a graph attention network for adaptive authentication and attack detection, showing improved accuracy and reduced overhead in simulated 6G environments.

    Distributed Physical Layer Authentication and Collaborative RSMA in Non-Terrestrial Networks via Graph Reinforcement Learning

    arXiv:2609.09475v1 Announce Type: cross Abstract: Existing physical-layer authentication (PLA) schemes for non-terrestrial networks (NTNs) often rely on single-anchor verification, lack joint authentication-transmission design, and ignore tag privacy leakage under eavesdropping. …

    Adaptive Distributed Physical-Layer Authentication and Attack Detection in 6G Non-Terrestrial Networks via Causal Meta-Learning

    arXiv:2609.09511v1 Announce Type: cross Abstract: Physical-layer authentication (PLA) in non-terrestrial networks (NTNs) is challenged by severe Doppler shifts, long delays, and fast channel variations, which cause distribution shifts and degrade conventional learning methods. Ex…
