Tspi_TPM_CollateIdentityRequest(3) TCG Software Stack Developer's Reference

NAME

Tspi_TPM_CollateIdentityRequest - Gets all the informatin necessary
to send to a trusted third party (TTP), repartory to asking the TTP
to create a certificate for identity.

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_CollateIdentityRequest(TSS_HTPM hTPM, TSS_HKEY hKeySRK,
TSS_HKEY hCAPPubKey,
UINT32 ulIdentityLabelData, BYTE* rgbIdentityLabelData,
TSS_HKEY hIdentityKey, TSS_ALGORITHM_ID algid,
UINT32* pulTCPAIdentityReqLength, BYTE** prgbTCPAIdentityReq);

DESCRIPTION

TSS_TPM_CollateIdentityRequest creates an identity key, binds it to
the label and returns a certificate request package. The privacty CA
requires this certificate request to attest the identity key.

Only the Owner of the TPM has the privledge of creating a TPM
identity key.

The symmetric session key is required to provide confidentiality of
the "TCPA_IDENTITY_REQ" data structure, which should be sent to the
Privacy CA chosen by the owner.

PARAMETERS

hTPM
Handle of the TPM object.

hKeySRK
Handle to the key object representing the Storage Root Key

hCAPubKey
Handle to the key object representing the public key of the CA which
signs the certificate of the created identity key.

ulIdentityLabelLength
Supplies the length (in bytes) of the rgbIdentityLabelData parameter

rgbLabelData
Pointer to a memory block containing the identity label, which should
be a UNICODE string

hIdentityKey
Handle to the identity key object

algid
The type of symmetric algorithm touse as requred by the Enhanced CA.

pulTCPAIdentityReqLength
Recieves the length (in bytes) of the prgbTCPAIdentityReq parameter

prgbTCPAIdentyReq
Pointer to the memory block containing the certicficate request
structure.

RETURN CODES

Tspi_TPM_CollateIdentityRequest returns TSS_SUCCESS on success,
otherwise one of the following values are returned:

TSS_E_INVALID_HANDLE
Either hTPM or hKeySRK or hCAPubKey is not a valid handle.

TSS_E_BAD_PARAMETER


TSS_E_INTERNAL_ERROR
An error occurred internal to the TSS.

CONFORMING TO

Tspi_TPM_CollateIdentityRequest conforms to the Trusted Computing
Group Software Specification version 1.1 Golden
