NAME

       Tspi_DAA_IssuerKeyVerification - verifies the DAA public key

SYNOPSIS

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

       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 con-
       suming 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.

CONFORMING TO

       Tspi_DAA_IssuerKeyVerification conforms to the Trusted Computing Group Software Specification version 1.2
