Abstract
A method for binding applications to a platform root of trust includes pre-provisioning application binding components in an information handling system. An application requesting OS access sends its access control list (ACL) and application metadata to the BIOS, which performs initial checks. The BIOS responds with platform metadata and a first nonce. The application communicates the metadata, the first nonce and a second nonce to a server. The server checks the nonces and metadata, creates a third nonce and an application binding object (ABO). The application checks the nonces and sends a binding certificate to the BIOS. The BIOS checks the nonces, creates a binding certificate, verifies the binding certificate and sends a binding session credential (BSC) to the application. The application binds the BSC with platform credentials.
