A satellite safe access authentication method and a system

Abstract

The invention discloses a satellite safe access authentication method and a system, comprising the following steps: a terminal equipment initiates a registration process, a ground station distributesan identity mark to the terminal equipment, and the ground station sends the terminal equipment identity information to the satellite to complete the terminal equipment registration process. The terminal equipment initiates the access authentication request, the ground gateway station judges the access state, the satellite receives the access authentication request, and sends the access authentication response to the terminal equipment after the multi-dimensional authentication, thereby completing the access authentication process of the terminal equipment. When the current connected satelliteis overtopped, the ground gateway station initiates a connection authentication request to the newly connected satellite, the satellite receives the connection authentication request, and sends a connection authentication response to the ground gateway station after multi-dimensional verification, thereby completing the terminal equipment connection authentication process. The terminal device initiates a logout authentication request, the ground gateway station judges the access state, the satellite receives the logout authentication request, and sends a logout authentication response to theterminal device after multi-dimensional authentication, thereby completing the logout authentication process of the terminal device.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a method and system for satellite security access authentication. Background technique [0002] With the continuous development of the terrestrial Internet, the use of satellite networks to provide network services to any user anywhere in the world, and to build a "space-ground integrated network" has become an important trend in the development of satellite networks. The satellite network is largely different from the traditional terrestrial network. On the one hand, compared with traditional terrestrial networks, space networks are more open, which makes security crucial to communication in space-ground integrated networks; on the other hand, due to the high-speed dynamic movement of satellites, in order to ensure The business service is not interrupted, and the ground gateway station needs to frequently carry out terminal equipment session connection betw...
