PLATFORM AUTHENTICATION MESSAGE MANAGEMENT METHOD SUITABLE FOR TRI-ELEMENT PEER AUTHENTICATION TRUSTED NETWORK CONNECT STRUCTURE

摘要

The present invention discloses a platform authentication message management method suitable for Tri-element Peer Authentication (TePA) Trusted Network Connect (TNC) structure. The method includes the following steps: step 1, the integrity measurement layer completes the management of platform component information, platform component repair information and message process error information of the integrity measurement layer; step 2, the trusted platform evaluation layer manages messages of itself according to the platform authentication protocol, and completes the management of the elements constituting the platform authentication protocol message; step 3, the message exchange management between the integrity measurement layer and trusted platform evaluation layer is implemented through the function between the Integrity Measurement Collector (IMC) and TNC Client (TNCC) in Access Requestor (AR), the function between the IMC and TNC Access Point (TNCAP) in Access Controller (AC), and the function between the Integrity Measurement Verifier (IMV) and Evaluation Policy Server (EPS) in Policy Manager.
