Credible inter-domain rapid authentication method on basis of separation mechanism network

Abstract

The invention relates to a fast authentication method between trusted domains based on a separation mechanism network to solve the problem of fast authentication when switching between terminal domains in the separation mechanism network. This method proposes a new protocol to realize fast authentication when the terminal is switched between domains, and realizes the identity authentication of the terminal platform and the integrity check of the terminal platform while authenticating the user identity. In this method, the authentication center of the home domain does not need to participate again when the terminal performs inter-domain switching, and the authentication center of the local domain can authenticate the mobile terminal through the Ticket. The method can resist the anti-replay attack, and guarantee the credibility, security, anonymity of the platform and the anonymity and untraceability of user identities.

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.

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.
