1. A two-phase access authentication method integrating spatial-temporal features in space-air-ground integrated networks, comprising the following steps:
S1, an initializing phase: selecting, by a ground network control center, a main key parameter, and selecting a matching hash function simultaneously;
S2, a device registration phase: performing identity information registration and spatial-temporal feature data acquisition in the ground network control center by a satellite having a legal permission and a user equipment respectively;
S3, a primary authentication phase: completing, by a user, local identity authentication, and achieving bidirectional authentication between the user equipment and the satellite under the assistance of the ground network control center simultaneously;
S4, a continued authentication phase: initiating, by the satellite, a continued authentication request and a spatial-temporal feature data acquisition request to the user equipment; sending, by the user equipment, acquired data to a satellite; and performing, by the satellite, continued authentication on the user equipment under the assistance of the ground network control center to output a final authentication decision.
