.SH "DESCRIPTION"
.PP
\Tspi_DAA_IssuerKeyVerification\fR
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.


.SH "PARAMETERS"
.PP
.SS hDAA
The \fIhDAA\fR parameter is used to specify the handle of the DAA object.
.SS issuerPk
The \fIissuerPk\fR parameter is a DAA Issuer public key.
.SS issuerPkProof
The \fIissuerPkProof\fR parameter is a structure representing the proofs of the correctness of the DAA Issuer public key.
.SS isCorrect
The \fIisCorrect\fR parameter is the return corectness of the proof.

.SH "RETURN CODES"
.PP
\fBTspi_DAA_IssuerKeyVerification\fR returns TSS_SUCCESS on success, otherwise one of the
following values is returned:
.TP
.SM TSS_E_INVALID_HANDLE
Either the DAA is not valid.
.TP
.SM TSS_E_BAD_PARAMETER
.TP
.SM TSS_E_INTERNAL_ERROR
An internal SW error has been detected.

.SH "CONFORMING TO"
.PP
\fBTspi_DAA_IssuerKeyVerification\fR conforms to the Trusted Computing Group
Software Specification version 1.2
