A kind of mobile access authentication method and device for integration of heaven and earth

Abstract

Embodiments of the present invention provide a space-ground integrated mobile access authentication method and device. The method includes: the space-based access point obtains the position change range between the user terminal and the space-based access point, and obtains the relative location of the user identity module. Change information between terminal devices; the user identity module is a device that stores the user's access ID and user certificate; the terminal device is a device for identifying the user identity module and receiving user authentication information; based on the position change range and change information, Perform access authentication on the user terminal. By comparing the access identification information in the user identity module and the information encrypted by the key in the certificate with the database of the authentication and authentication center, the user's authentication is realized; at the same time, it solves the problem of equipment caused by the relative movement of the access switch router and the user terminal Periodic network switching problem simplifies the procedure of user terminal access authentication and improves the access efficiency of user terminal.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a space-ground integrated mobile access authentication method and device. Background technique [0002] Among the various protocols to ensure network security, the authentication mechanism is the cornerstone of user access and network access, and is the first line of defense against network attacks. If there is no high-efficiency, high-robust, and sound access authentication mechanism, it will bring great security threats to the network. After years of development, the ground network has a systematic and hierarchical architecture, and the topology is relatively stable. The server has a large number of computing resources and the network bandwidth is abundant. Therefore, various access authentication mechanisms can fully play their roles. [0003] Different from ground-based networks, space-ground integrated information networks include heterogeneous networks such...
