Abstract: A method of signaling interaction in 5G space-ground integrated heterogeneous network architecture is provided, which enables publicly available data for trusted satellite discovery to be registered to the 5G core network based on the function framework of the 5G core network. When searching for satellites, a gNB can utilize the publicly available data of the trusted satellite registered in the 5G core network to speed up satellite searching, improve satellite link services, and filter out untrusted satellites. By the method provided by the present disclosure, it can effectively improve the satellite search speed in the 5G space-ground integrated architecture, improve satellite link availability, reduce authentication complexity of satellites in ground networks in heterogeneous network architecture.

Abstract: Disclosed is a two-phase access authentication method integrating spatial-temporal features in space-air-ground integrated networks. In the method, an access authentication is divided into two phases: a primary authentication phase and a continued authentication phase. In the primary authentication phase, a user equipment and a satellite are respectively initialized and registered through a ground network control center. In the authentication phase, a fast and secure access is achieved by using a user ID, facial features, and other authentication factors. In the continued authentication phase, data of a user flow and behavior features are acquired, and feature comparison is performed by using historical user data; and a security level and an authentication decision are output. According to the disclosure, the spatial-temporal features are integrated to perform access authentication on a satellite-ground communication network, the authentication not only achieves a fast access, but also continuously ensures the system security in a service phase.

Abstract: A method and a device for improving pipeline safety of a space-terrestrial network architecture. The method pre-registers the profile of a base station in the network repository function network element of a 5G core network; after receiving a relay pipeline connection establishment request initiated by a base station, a relay satellite sends a network function verification request to the network repository function network element through a network expose function network element; after receiving a response to a network function discovery request of the base station, the network expose function network element sets the corresponding verification result of the base station according to whether there is base station registration information and responds to a verification request of the network element; and finally, the relay satellite verifies the verification result cell carried in the received response to determine the legality of the current access to the base station.

Abstract: The present disclosure provides methods and apparatuses for improving user security of satellite-ground integrated network systems. On the basis of the satellite-ground integrated network pipeline only authenticates a terminal in a satellite-ground integrated network, a two-stage authentication based on CA digital certificates and user characteristic information is put forward for users and services using the terminal. The two-stage authentication includes: firstly, when a first spatio-temporal information ciphertext digest obtained from spatio-temporal information ciphertext in a service request by using a digest algorithm is consistent with a second spatio-temporal information ciphertext digest obtained by decrypting a digital signature in the service request using a user public key, the user is legal; furthermore, when spatio-temporal information characteristics obtained by decrypting the spatio-temporal information ciphertext using a private key of the satellite-ground integrated core network are consistent with spatio-temporal characteristics in the digital certificate, the verification succeeds.
