Abstract
Recently emerged 6G space-air-ground integrated networks (SAGINs), which integrate satellites, aerial networks, and terrestrial communications, offer ubiquitous coverage for various mobile applications. However, the highly dynamic, open, and heterogeneous nature of SAGINs poses severe security issues. Forming a defense line of SAGINs suffers from two preliminary challenges: 1) accurately understanding massive unstructured multi-dimensional threat information to generate defense strategies against various malicious attacks, 2) rapidly adapting to potential unknown threats to yield more effective security strategies. To tackle the above two challenges, we propose a novel security framework for SAGINs based on Large Language Models (LLMs), which consists of two key ingredients LLM-6GNG and 6G-INST. Our proposed LLM-6GNG leverages refined chain-of-thought (CoT) reasoning and dynamic…
