Abstract:
1. A platform authentication method applied in a trusted network connect architecture based on tri-element peer authentication, wherein a TNC client, a TNC access point and an evaluation policy server perform a tri-element peer authentication protocol, and the platform authentication method applied in the trusted network connect architecture based on the tri-element peer authentication comprises: interacting with messages, between the TNC access point and the TNC client, to request for an integrity measurement value of each other's platform, and verify a platform signature on the integrity measurement value of the each other's platform; and interacting with messages, between the TNC access point and the evaluation policy server, so that the evaluation policy server verifies validity of a platform identity certificate and evaluates the integrity measurement value, comprising: step 1), generating, by the TNC access point, an integrity measurement parameter for an access requester Parms step 2), sending, by the TNC client upon receipt of the message 1, a message 2 to the TNC access point, the message 2 comprising an integrity measurement value of the access requester IntegrityInfo step 3), sending, by the TNC access point upon receipt of the message 2, a message 3 to the evaluation policy server, the message 3 comprising a platform authentication verification challenge from the access controller N step 4), sending, by the evaluation policy server upon receipt of the message 3, a message 4 to the TNC access point; sending, by the TNC access point upon receipt of the message 4, a message 5 to the TNC client; and sending, by the TNC client upon receipt of the message 5, a message 6 to the TNC access point, the message 6 comprising the platform authentication activation challenge from the access controller N step 5), upon receipt of the message 6, if the access decision for the access requester Action
