NAME

Tspi_TPM_DAA_JoinStoreCredential - compute the final DAA Credential

SYNOPSIS

#include <tss/tss_typedef.h>
#include <tss/tss_structs.h>
#include <tss/tspi.h>

TSS_RESULT Tspi_TPM_DAA_JoinStoreCredential(
    TSS_HDAA                    hDAA,
    TSS_HTPM                    hTPM,
    TSS_DAA_CRED_ISSUER         credIssuer,
    TSS_DAA_JOIN_SESSION        joinSession,
    TSS_HKEY*                   hDaaCredential
);

DESCRIPTION

Tspi_TPM_DAA_JoinStoreCredential is the last out of 3 functions (after Tspi_TPM_DAA_JoinInit() and Tspi_TPM_DAA_JoinCreateDaaPubKey())
to execute in order to receive a DAA Credential. It verifies the issued credential from the DAA Issuer and computes the final DAA Credential.

PARAMETERS

hDAA

The hDAA parameter is used to specify the handle of the DAA object.

hTPM

The hTPM parameter is the handle to the TPM object.

credIssuer

The credIssuer parameter is the DAA Credential issued by the DAA Issuer including proof of correctness.

joinSession

The joinSession parameter is the structure containing the DAA Join session information.

hDaaCredential

The hDaaCredential parameter is the handle of the received DAA Credential.

RETURN CODES

Tspi_TPM_DAA_JoinStoreCredential returns TSS_SUCCESS on success, otherwise one of the following values is returned:

TSS_E_INVALID_HANDLE: Either the DAA or the TPM handler is not valid.
TSS_E_BAD_PARAMETER
TSS_E_INTERNAL_ERROR: An internal SW error has been detected. TSS_E_DAA_CREDENTIAL_PROOF_ERROR One of the verification of the issued credential failed

CONFORMING TO

Tspi_TPM_DAA_JoinStoreCredential conforms to the Trusted Computing Group Software Specification version 1.2
