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.
