TPM Win32_TPM Class Test

  • Articolo

This test runs the TPM WMI hardware certification tests. In the setup steps, the test disables auto provisioning of the TPM and requests a TPM clear operation from firmware. The following test actions are performed using the Win32_TPM class:

  1. Check the Win32_TPM class properties

  2. Check GetPhysicalPresenceTransition = 2 (Reboot)

  3. Check PhysicalPresenceVersionInfo = “1.2”

  4. Check for the presence of an Endorsement key

  5. Take ownership of the TPM

  6. Change the ownerAuth

  7. Disable the TPM (if allowed)

  8. Verify that IsEnabled is true for TPM 2.0 and false for TPM 1.2

  9. Enable the TPM

  10. Verify that IsOwnerClearDisabled is true

  11. Clear the TPM through WMI (should fail because owner clear is disabled)

  12. Create an Endorsement Key Pair (should fail because one already exists)

  13. IsPhysicalClearDisabled (result can be true or false, but not an error)

  14. IsPhysicalPresenceHardwareEnabled (result can be true or false, but not an error)

  15. IsSrkAuthCompatible must return true

  16. ResetAuthLockOut must return success

  17. ResetSrkAuth

  18. SelfTest
