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.
