A 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. After the terminal has successfully registered with the security management and control center, if it needs to access the satellite network, it generates access authentication request information and sends the access authentication request The information is sent to the Satcom base station; the access authentication request information includes at least: anonymous identity information, the first token parameter and the second token verification parameter, the anonymous identity information and the first token parameter are generated according to the real identity of the terminal , the second token verification parameter is generated according to the second token parameter and related authentication request parameters. The Satcom base station can verify the authentication request information according to the preset relationship between the second token verification parameter and the first token parameter. If the verification is passed, an authentication response message is generated and sent to the corresponding terminal for verification. Therefore, the main access authentication calculation is moved forward to the Satcom base station, which effectively reduces the authentication transmission delay and improves the access authentication performance.

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
