Graph Reinforcement Learning for Physical-Layer Authentication in Non-Terrestrial Networks

A new arXiv paper proposes a framework that unifies physical-layer device authentication with rate-splitting multiple access (RSMA) transmission in non-terrestrial networks, coordinating verification across multiple anchors rather than a single one. The authors use graph reinforcement learning to jointly design authentication and communication while limiting tag privacy leakage to eavesdroppers.

Causal Meta-Learning for Physical-Layer Authentication in 6G Non-Terrestrial Networks

A new arXiv preprint introduces an adaptive, distributed physical-layer authentication and attack detection method built on causal meta-learning for 6G non-terrestrial networks. The work targets settings such as satellite links, where Doppler shifts, long delays, and fast-changing channels create distribution shifts that undermine conventional learning-based defenses.
