Abstract

A trusted network connect (TNC) method based on tri-element peer authentication is provided, which includes the following steps. Platform integrity information is prepared in advance. An integrity verification requirement is predefined. A network access requestor initiates an access request to a network access controller. The network access controller starts a mutual user authentication process, and performs a tri-element peer authentication protocol with a user authentication serving unit. After the mutual user authentication is successful, a TNC client, a TNC server, and a platform evaluation serving unit implement platform integrity evaluation by using a tri-element peer authentication method. The network access requestor and the network access controller control ports according to recommendations received respectively, so as to implement mutual access control between the access requestor and the access controller. Thus, the technical problems in the prior art of poor extensibility, complex key agreement process, low security, and that platform integrity evaluation is not peer-to-peer are solved by the present invention. Through the method of the present invention, key managemen…
