A TRUSTED NETWORK CONNECT SYSTEM BASED ON THREE-ELEMENT PEER AUTHENTICATION

摘要

A trusted network connect system based on three-element peer authentication is provided. In the system, a network access requestor of access requestor connects with a TNC client in a data carrying way. The TNC client connects with an integrity collector by an integrity measurement collection interface. A network access controller of access controller connects with a TNC server in a data carrying way. The TNC server connects with an integrity collector by an integrity measurement collection interface. A user authentication service unit of policy manager connects with a platform evaluation service unit in a data carrying way. The platform evaluation service unit connects with an integrity verifier by an integrity measurement verification interface. The technical problems in the background art such as poor extensibility, complicated key negotiation process, relatively low security and so on are solved. Both network access layer and integrity evaluation layer adopt three-element peer authentication to implement bidirectional user authentication and platform integrity evaluation, thus the security of the whole trusted network connect architecture can be improved.
