Embodiment Construction

[0034] Since most of the existing networks are deployed using the TCG-TNC architecture, especially the wired network, the present invention is a trusted network connection architecture with enhanced security built on the TCG-TNC architecture.

[0035] Referring to Fig. 2, the present invention is mainly composed of four logical entities: an access requester AR, a policy enforcement point PEP, an access authorizer AA and a policy manager PM, which can be distributed anywhere in the network. The access requester AR is also called requester, user station, etc., and the policy manager PM is also called authentication server, trusted server, background server, etc. The access requester AR and the policy enforcement point PEP are connected to the network through the authentication protocol, the policy enforcement point PEP and the access authorizer AA are connected through the network through the policy enforcement interface IF-PEP, and the access requester AR and the access authoriz...

Abstract

The invention relates to a safety-enhanced trusted network connecting system, the access requestor is network connected with a policy enforcement point in authentication protocol manner, the access requestor is network connected with an access authorizer by network authorizing transmission protocol interface, integrity evaluation interface and integrity measurement interface, the policy enforcement point is network connected with the access authorizer by policy implementation interface, the access authorizer is network connected with a policy manager by user identification authorization interface, platform evaluation authorization interface and integrity measurement interface, the access requestor is network connected with the policy manager by integrity measurement interface. The invention solves following technology problems: low security, inability of the access requestor to verify the validation of AIK certificate, and non-equivalence of platform integrity evaluation. The invention employs three-element equivalent identification protocol in network access layer and integrity evaluation layer, which improves the whole trusted network connection architecture and extends the application scope of trusted network connection.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a trusted network connection system with enhanced security. Background technique [0002] With the development of informatization, the problems of malicious software such as viruses and worms are extremely prominent. There have been more than 35,000 kinds of malicious software, and more than 40 million computers are infected every year. To contain such attacks, it is necessary not only to solve the problem of secure transmission and data input checks, but also to start defense from the source, that is, from every terminal connected to the network. However, traditional security defense technologies have been unable to defend against a wide variety of malicious attacks. [0003] In response to this problem, the International Trusted Computing Group TCG has specially formulated a network connection specification based on trusted computing technology - Trusted ...
