Hybrid orbit endogenous secure satellite authentication technology

Satellite Internet has the characteristics of wide-area coverage, flexible deployment, high bandwidth and low latency, which can cover remote areas that are hard to reach by terrestrial networks and provide Internet services. Aiming at the current problem that terminal access authentication is carried out locally at the gateway station, the service scope is limited and there is a single point of failure of the server, as well as the risk of centralised data leakage during the authentication process, this paper proposes a hybrid orbital endogenous security authentication technique combining GEO and LEO using the relative position invariance of GEO and the high efficiency of LEO data transmission to improve the robustness, scalability and security of the system. Simulation results show that the scheme has better delay and throughput performance while ensuring authentication security.
