Embodiment Construction

[0021] Such as figure 1 As shown, the links involved in the satellite communication network architecture adopted by the present invention include: inter-satellite link, user link, feeder link and safety channel.

[0022] The meanings of the marks used in the present invention are: U: terminal user, SAT: satellite, G: gateway station, G': registered gateway station, NCC: network control center.

[0023] Message Authentication Code (MAC): In cryptography, a verification mechanism used by both communicating entities, a tool to ensure the integrity of message data, can also be called a hash function with a secret key. The message authentication code is a value obtained based on the key and the message digest, which can be used for data source authentication and integrity verification.

[0024] The gateway station-based satellite network anonymous authentication method provided by the present invention mainly has two stages of registration and authentication, and the main process ...

Abstract

The present invention provides a gateway station-based satellite network anonymous authentication method. The conventional satellite network authentication methods all adopt a network control center (NCC) to authenticate users, and in order to reduce the authentication calculation amount of the NCC, the gateway station-based satellite network anonymous authentication method of the present invention enables an authentication function to transfer to a gateway station G, thereby relieving the burdens of the NCC. The gateway station-based satellite network anonymous authentication method of the present invention adopts a message authentication code (MAC) during an authentication process, thereby realizing the anonymous authentication of the users, and protecting the privacy of the users. According to the present invention, after the security authentication of a satellite network to the users is realized, the security authentication of the users to the satellite network is finished, thereby achieving a bidirectional authentication purpose, and further improving the network security. The authentication method of the present invention mainly comprises two stages, namely a registration stage and an authentication stage.

Description

technical field [0001] The invention relates to a satellite network anonymous authentication method based on a gateway station, which realizes the two-way authentication between the user and the satellite network and further improves the security of the network, and belongs to the technical field of satellite communication. Background technique [0002] Due to the openness of satellite network channels, the security of satellite networks cannot be ignored, especially in military and commercial applications. Although satellite communication technology is relatively mature, the safety protection technology is still in the stage of theoretical exploration and experimentation, and a lot of research work is still needed. How to build a trusted satellite network, how to achieve confidential communication, and how to confirm the identity information of business participants, these security issues must be considered and resolved when we build a satellite network. [0003] Users can...
