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.

The \fIhTPM\fR parameter is used to specify the handle of the TPM object.
The \fIhKeySRK\fR parameter is the handle to the object representing the TPM's Storage Root Key.
.SS hEndorsementPubKey
The \fIhEndorsementPubKey\fR 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.

\fBTspi_TPM_TakeOwnership\fR returns TSS_SUCCESS on success, otherwise one of the
following values is returned:
Either the TPM or one of the key handles is not valid.

An internal SW error has been detected.


\fBTspi_TPM_TakeOwnership\fR conforms to the Trusted Computing Group
Software Specification version 1.1 Golden
