Satellite network terminal security access authentication method, device and system

Abstract

The invention discloses a satellite network terminal security access authentication method, device and system; the method comprises the steps: generating access authentication request information if a terminal needs to access a satellite network after the terminal is successfully registered in a security management and control center, and transmitting the access authentication request information to a satellite communication base station, wherein the access authentication request information at least comprises anonymous identity information, a first token parameter and a second token verification parameter, the anonymous identity information and the first token parameter are generated according to a real identity label of the terminal, and the second token verification parameter is generated according to the second token parameter and a related authentication request parameter; verifying, by the satellite communication base station, the authentication request information according to a preset relationship between the second token verification parameter and the first token parameter; and if the verification is passed, generating authentication response information, and sending the authentication response information to the corresponding terminal for verification. Therefore, the main access authentication calculation is moved forward to the satellite communication base station, the authentication transmission delay is effectively reduced, and the access authentication performance is improved.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a satellite network terminal security access authentication method, device and system. Background technique [0002] With the development of communication technology, the application of satellite communication is more and more extensive, and the terminal needs to perform access authentication before accessing the satellite network for communication. [0003] In the existing technology, the following two methods are usually used for access authentication. The first method is central authentication, that is, access authentication is performed through the security control center. In this method, the terminal needs to pass the authentication request information through the satellite communication base station and satellite Transmission to the security management and control center, therefore, the data transmission of method 1 is complicated, and it is easy to cause a large auth...

Problems solved by technology

[0003] In the existing technology, the following two methods are usually used for access authentication. The first method is central authentication, that is, access authentication is performed through the security control center. In this method, the terminal needs to pass the authentication request information through the satellite communication base station and satellite Transmission to the security management and control center, therefore, the data transmission of method 1 is complicated, and it is easy to cause a large authentication transmission delay

The second way is to rely on satellites for authentication, that is, access authentication through satellites. However, satellite resources are limited, and it is difficult to ensure sufficient security strength due to the limitation of relatively high authentication lightweight requirements.

Some of the above disadvantages in the existing authentication methods will affect the access authentication performance and user experience
