TSS_RESULT Tspi_TPM_TakeOwnership(TSS_HTPM hTPM, TSS_HKEY hKeySRK,
TSS_HKEY hEndorsementPubKey);
DESCRIPTION¶
Tspi_TPM_TakeOwnership takes ownership of a TPM. Taking ownership is the
process of inserting a shared secret into the TPM. The owner of the TPM
(anyone who knows the shared secret) has the right to perform special
operations.
PARAMETERS¶
hTPM¶
The
hTPM parameter is used to specify the handle of the TPM object.
hKeySRK¶
The
hKeySRK parameter is the handle to the object representing the TPM's
Storage Root Key.
hEndorsementPubKey¶
The
hEndorsementPubKey parameter is the handle to the object representing
the TPM's endorsement public key. This key is required for encrypting the
secret of the SRK and the TPM owner secret. If NULL, the TSP internally
queries the TPM for that endorsement public key.
RETURN CODES¶
Tspi_TPM_TakeOwnership returns TSS_SUCCESS on success, otherwise one of
the following values is returned:
- TSS_E_INVALID_HANDLE
- Either the TPM or one of the key handles is not valid.
- TSS_E_INTERNAL_ERROR
- An internal SW error has been detected.
Tspi_TPM_TakeOwnership conforms to the Trusted Computing Group Software
Specification version 1.1 Golden
