Abstract: The complexity and heterogeneity of space-terrestrial integrated networks introduce multi-dimensional security threats and challenges to 6G systems. The security challenges faced by 6G space-terrestrial integrated networks are systematically analyzed. Based on existing mobile communication systems and considering the network architecture and characteristics, it identifies security requirements and proposes a corresponding security reference framework. The study focuses on the application of key technologies such as wireless communication security, user access authentication, and privacy protection in space-terrestrial integrated networks. The research demonstrates that establishing a security technology system tailored to the unique features of space-terrestrial integrated networks is fundamental to ensuring 6G network security.
