Problems solved by technology

The above-mentioned fast inter-domain authentication method only realizes the authentication of the identity of the terminal user, but does not realize the authentication of the platform identity and platform credibility of the terminal
At present, the main threat to information security comes from the inside. If the user platform is invaded by viruses or maliciously modified, it will cause great hidden dangers to the security of the network.

Embodiment Construction

[0033] The present invention will be described in detail below.

[0034] The model framework of inter-domain fast authentication is as follows: figure 1 shown.

[0035] In this model, it is divided into home network, foreign network, Internet, and other networks. The home network and the foreign network are connected in a wired manner. They are connected to the Internet through the generalized switching router GSR, and the Internet is connected to other networks. Deployed generalized switching routers GSR, ASR, AC in the home network H , Privacy-CA and MN. Deployed GSR, ASR, AC in the foreign network F , Privacy-CA. The GAC is deployed in the Internet.

[0036] The mobile node MN is a trusted wireless terminal device embedded with a TPM chip, and the MN accesses the network in a wireless manner. In the home network, the MN accesses through the ASR. When the MN accesses the network, the AC H Together with Privacy-CA, conduct identity authentication and platform verific...

Abstract

The invention relates to a credible inter-domain rapid authentication method on the basis of a separation mechanism network for solving the problem of rapid authentication when a terminal in the separation mechanism network is subjected to inter-domain switching. In the method, a novel protocol is provided for realizing the rapid authentication when the terminal is subjected to inter-domain switching; and when the identity of a user is authenticated, the identity authentication of a terminal platform and the integrity check of the terminal platform are realized. In the method, when the terminal is subjected to inter-domain switching, an authentication center of a home domain does not need to participate again and an authentication center of a local domain can authenticate the mobile terminal by a Ticket. The method can resist the anti-replay attack, so that the credibility, safety, anonymity, anonymity of the identity of the user and untraceability of the identity of the user of the platform are ensured.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a fast authentication method between trusted domains based on a separation mechanism network. Background technique [0002] In the separation mechanism network, when the location of the terminal changes, that is, when it is switched from one access switch router to another, in order to ensure the security of the terminal and the network, the terminal needs to be re-authenticated in time. The re-authentication at this time is different from the full authentication when the terminal accesses the network. Full authentication generally has a long time delay. The endured delay is not suitable for some real-time services, especially the real-time transmission of audio and video. Therefore, in the separation mechanism network, it is necessary to design an inter-domain fast authentication method when the terminal moves and switches. [0003] Inter-Domain Fast Authentication (Inter-Doma...
