Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, the security authentication between the network operation control center and the satellite is mainly divided into three steps, and the specific description is as follows:

[0019] Step 1: The party that needs to initiate communication, since the communication process is equivalent and can be exchanged, assuming that the network operation control center initiates communication, the network operation control center will send the pseudonym and certificate of the machine to the satellite for authentication;

[0020] Step 2: After receiving the message, the satellite first calculates the Compressed Bloom Filters value of the sender's pseudonym, and conducts preliminary authentication to check whether the sender is trustworthy. If the pseudonym verification fails, the authentication fails and ends. Communication, if the auth...

Abstract

Provided is a credible authentication system between a ground network operation control center and a satellite under the environment of interconnection of mobile grids. Whether a node requesting authentication is within a legitimate node area is judged in a Compressed Bloom Filter method, and only when the node passes the judgment can a certificate be verified. If the judgment is not firstly carried out, an illegal node may constantly send false certificates to the legitimate node, the legitimate node constantly carries out a large-number exponent arithmetic, and in terms of a satellite node with limited resources, paralysis of the satellite node is caused. Therefore, the credible authentication system can effectively defend attacks of denial of service in authentication.

Description

technical field [0001] The invention relates to a network authentication system, especially a trusted authentication system between a network operation control center and a satellite. Background technique [0002] Under the complex geographical conditions of our country, it is an effective solution to adopt satellite network technology. Satellite networks have been widely favored by operators around the world in traditional services such as radio, television, and language. In addition, satellite networks can also play an important role in emergency communications in extreme climates and conditions such as earthquakes, snowstorms, and tsunamis. [0003] A mobile grid environment requires all communication entities to be IP-based and support various broadband access technologies and mobile user applications. This requires the satellite network not only to be a supplementary method to the ground network, but also to become an Internet-oriented satellite network as an important...
