+.SH "DESCRIPTION"
+.PP
+\Tspi_TPM_DAA_JoinCreateDaaPubKey\fR
+is the second (between \fBTspi_TPM_DAA_JoinInit()\fR and \fBTspi_TPM_DAA_JoinStoreCredential()\fR)
+ out of 3 functions to execute in order to receive a DAA Credential.
+It computes the credential request for the DAA Issuer, which also includes the Platforms's
+DAA public key and the attributes that were chosen by the Platform, and which are not visible
+to the DAA Issuer. The Platform can commit to the attribute values it has chosen.
+.SH "PARAMETERS"
+.PP
+.SS hDAA
+The \fIhDAA\fR parameter is used to specify the handle of the DAA object.
+.SS hTPM
+The \fIhTPM\fR parameter is the handle to the TPM object.
+.SS authenticationChallengeLength
+The \fIauthenticationChallengeLength\fR parameter is length of authenticationChallenge (256 bytes - DAA_SIZE_NE1).
+.SS authenticationChallenge
+The \fIauthenticationChallenge\fR parameter is the second nonce of the DAA Issuer that is encrypted by the endorsement public key.
+It is used as a challenge to authenticate the underlying TPM.
+.SS nonceIssuerLength
+The \fInonceIssuerLength\fR parameter is the length of nonceIssuer (20 bytes).
+.SS nonceIssuer
+The \fInonceIssuer\fR parameter is the nonce of the DAA Issuer.
+.SS attributesPlatformLength
+The \fIattributesPlatformLength\fR parameter is length of attributesPlatform array, which is determined
+by the DAA Issuer public key (). The length of a single attribute is ln/8. ln is defined as the size of
+the RSA modulus (2048).
+.SS attributesPlatform
+The \fIattributesPlatform\fR parameter is an array of attributes to be encoded into the DAA Credential
+not visible to the DAA Issuer.
+.SS joinSession
+The \fIjoinSession\fR parameter is a structure containing the DAA Join session information.
+.SS credentialRequest
+The \fIcredentialRequest\fR parameter is the credential request of the Platform, it contains the blinded
+DAA public key of the platform on which the DAA Issuer will issue the credential the blinded attributes
+chosen by the Platform.
+
+.SH "RETURN CODES"
+.PP
+\fBTspi_TPM_DAA_JoinCreateDaaPubKey\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_TPM_DAA_JoinCreateDaaPubKey\fR conforms to the Trusted Computing Group
+Software Specification version 1.2
