Embodiment approach

[0095] like figure 2 As shown, the mobile user network access authentication method designed by the present invention mainly consists of four steps: user registration, user management, mobile authentication and update authentication. The specific implementation of each step is as follows:

[0096] (1) User registration

[0097] Before using the network, the user U first needs to register with the NCC, and the NCC will assign user information to it. The information assigned by the NCC to the new user U includes: the user's permanent identity ID U ; Shared authentication key K between user and NCC A and allow K A The maximum number of times N used U , K A Generated by NCC when the user registers, and updated every time the authentication is renewed; the user's temporary identity TID U , generated by NCC when the user registers, and updated every time the authentication is updated; S U It is used to identify whether NCC can provide network access authentication service f...

Abstract

The invention relates to a network access authentication method applicable to a satellite mobile communication network. The network access authentication method comprises four steps of user registration, user management, mobile authentication and update of authentication; an effective network access authentication protocol is of great importance for the security of the satellite mobile communication network. The network access authentication method is characterized in that the authentication role of a gateway station is emphasized and the authentication calculation load of an NCC (Network Control Center) is reduced; common attacks such as masquerading, tampering and replay of any party can be resisted, and meanwhile, integrity protection on the transmitted data is realized, and therefore, the security of the satellite mobile communication network is greatly improved.

Description

technical field [0001] The invention relates to a network access authentication method suitable for a satellite mobile communication network, and belongs to the technical field of satellite network security authentication. Background technique [0002] With the development of communication technology, the satellite mobile communication network has attracted more and more attention. It has the following advantages: it can provide remote ground network connections, direct access to the network, Internet services, multimedia applications, and high-speed transmission. A typical satellite mobile communication network consists of satellites, gateway stations, mobile users, network control center (NCC) and satellite control center (SCC), such as figure 1 shown. [0003] The space segment of the satellite mobile communication network is composed of satellites, and the space segment is one or more satellite constellations, providing connections between mobile users and gateway stati...
