TSPICALL Tspi_DAA_IssuerKeyVerification(
TSS_HDAA hDAA,
TSS_HKEY issuerPk,
TSS_DAA_PK_PROOF* issuerPkProof,
TSS_BOOL* isCorrect
);

DESCRIPTION

Tspi_DAA_IssuerKeyVerification verifies the DAA public key of a DAA Issuer with respect to its associated proof. This is a resource consuming task. It can be done by trusted third party (certification). This is an optional function and does not require a TPM or a TCS.

PARAMETERS

hDAA

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

issuerPk

The issuerPk parameter is a DAA Issuer public key.

issuerPkProof

The issuerPkProof parameter is a structure representing the proofs of the correctness of the DAA Issuer public key.

isCorrect

The isCorrect parameter is the return corectness of the proof.

RETURN CODES

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

TSS_E_INVALID_HANDLE

Either the DAA is not valid.

TSS_E_BAD_PARAMETER

TSS_E_INTERNAL_ERROR

An internal SW error has been detected.
