Trusted network connect handshake method based on tri-element peer authentication

A trusted network connect handshake method based on Tri-element Peer Authentication, comprising the steps of:

• 1) transmitting by an access controller to an access requester a message 1 for handshake activation comprising an authentication identifier NAC of the access controller, a platform identity certificate CertAIK-AC of the access controller, platform integrity measurement information ParmP-AR requested by the access controller from the access requester, a user identity certificate CertUser-AC of the access controller, an ECDH parameter ParmECDH for key negotiation, and another parameter Text1;
• 2) transmitting by the access requester an access and handshake request message 2 for access handshake request to the access controller upon reception of the message 1;
• 3) transmitting by the access controller a message 3 for certificate authentication and integrity evaluation request to a policy manager upon reception of the message 2;
• 4) transmitting by the policy manager a message 4 for certificate authentication and integrity evaluation response to the access controller upon reception of the message 3;
• 5) transmitting by the access controller an message 5 for access handshake response to the access requester upon reception of the message 4;
• and
• 6) performing a trusted network connect handshake by the access requester upon reception of the message 5.
