Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] Such as figure 1 As mentioned above, it is a space-ground integrated network architecture diagram, which mainly includes the following entities: terminal user U, satellite access point, gateway station GS, and network control center (NCC). In order to reduce user access delay, the present invention adopts low-orbit satellite (LEO) as a satellite access point, and authenticates user legitimacy by the low-orbit satellite.

Abstract

The invention discloses a low-latency anonymous access authentication method for space information network integrated with space and ground. The method can effectively judge the legitimacy of users, avoid illegal access to network resources by illegal users, and effectively ensure the integration of space and ground. Network security, the invention transfers the authentication function to the satellite, which greatly reduces the time delay for users to access the network. While maintaining privacy, it is possible to reveal the true identity of malicious users and hold them accountable.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a low-latency anonymous access authentication method for a space-ground integrated space information network. Background technique [0002] At present, the space-ground integrated network formed by the fusion of satellite networks, terrestrial networks and other networks has attracted widespread attention from academia and industry due to its advantages such as wide-area coverage, no geographical restrictions, and strong emergency response capabilities. However, the highly open nature of the space-ground integrated network communication channel makes it face many security threats such as information theft and entity deception. Among them, in order to prevent illegal users from illegally accessing the space-ground integrated network to obtain network services or damage the system, before users access the network, the access network needs to authenticate the user's l...
