NAME
Tspi_TPM_TakeOwnership - take ownership of a TPM SYNOPSIS
#include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> 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 en- crypting 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. CONFORMING TO
Tspi_TPM_TakeOwnership conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO

NAME
Tspi_TPM_ClearOwner - clear TPM ownership SYNOPSIS
#include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> TSS_RESULT Tspi_TPM_ClearOwner(TSS_HTPM hTPM, TSS_BOOL fForcedClear); DESCRIPTION
Tspi_TPM_ClearOwner wipes the TPM of everything but its endorsement key. It will wipe the SRK, so anything locked to the SRK will also dis- appear when this command is executed. This is the only way to be certain that keys are gone, as it is the only way to guarantee that noth- ing can keep a copy of the key. You must assert either physical presence or owner authorization in order to use this command. PARAMETERS
hTPM The hTPM parameter is used to specify the handle of the TPM object. fForcedClear The fForcedClear parameter is used to tell whether this command is being executed with owner authorization or with physical presence. If FALSE, then TPM owner authorization is used. If TRUE, then physical presence is required to clear the TPM. RETURN CODES
Tspi_TPM_ClearOwner returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hTPM is not a valid handle. TSS_E_INTERNAL_ERROR An internal SW error has been detected. CONFORMING TO
Tspi_TPM_ClearOwner conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO
