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.
