.SH "DESCRIPTION"
.PP
\Tspi_DAA_IssueSetup\fR
is part of the DAA Issuer component. It defines the generation of a DAA Issuer
public and secret key. Further it defines the generation of a non-interactive proof (using
the Fiat-Shamir heuristic) that the public keys were chosen correctly. The latter will guarantee
the security requirements of the platform (respectively, its user), i.e., that the privacy and
anonymity of signatures will hold.
The generation of the authentication keys of the DAA Issuer, which are used to authenticate
(main) DAA Issuer keys, is not defined by this function.
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 issuerBaseNameLength
The \fIissuerBaseNameLength\fR parameter is the length of the issuerBaseName.
.SS issuerBaseName
The \fIissuerBaseName\fR parameter is the unique name of the DAA Issuer.
.SS numberPlatformAttributes
The \fInumberPlatformAttributes\fR parameter is the number of attributes that the Platform can choose and which will not be visible to the Issuer.
.SS numberIssuerAttributes
The \fInumberIssuerAttributes\fR parameter is number of attributes that the Issuer can choose and which will be visible to both the Platform and the Issuer.
.SS keyPair
The \fIkeyPair\fR parameter is the handle of the main DAA Issuer key pair (private and public portion).
.SS publicKeyProof
The \fIpublicKeyProof\fR parameter is the Handle of the proof of the main DAA Issuer public key.

.SH "RETURN CODES"
.PP
\fBTspi_DAA_IssueSetup\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_IssueSetup\fR conforms to the Trusted Computing Group
Software Specification version 1.2
