Just as the TPM uses an EK Credential to establish trust, the Platform Certificate is used to validate the platform itself. The ACA requires that the Platform Certificate's certificate chain is uploaded via the Trust Chain page of the ACA prior to performing any validation of Platform Certificate.

The user can view the uploaded Platform Certificate by clicking the clipboard icon under the Options tab, which will give the user a variety of details about the manufacturer of the device and the components contained within:

Note

When a Platform Certificate's signature is validated via the Trust Chain, a clipboard icon will appear in the Issuer section. If any certificate is missing the chain, a clipboard icon will appear instead.

Fields of particular note when viewing a Platform Credential:

  • The Holder field contains the CN and Certificate serial number of the EK Credential. The serial number will hyperlink to the EK Credential, if present on the EK Credential page.
  • The System Platform Information field contains information about the system’s manufacturer. The system information is defined by SMBIOS and adopted by most major computer manufacturers.
  • The Components section contains information about components within, to include manufacturer, model, serial number, and revision.
