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

NAME

       Tspi_DAA_IssueInit - initialize the Issuer for a join operation

SYNOPSIS

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

       TSPICALL Tspi_DAA_IssueInit(
	   TSS_HDAA			 hDAA,
	   TSS_HKEY			 issuerAuthPK,
	   TSS_HKEY			 issuerKeyPair,
	   TSS_DAA_IDENTITY_PROOF	 identityProof,
	   UINT32			 capitalUprimeLength,
	   BYTE*			 capitalUprime,

	   TSS_DAA_JOIN_ISSUER_SESSION*  joinSession
       );

DESCRIPTION

       Tspi_DAA_IssueInit is a function that is part of the DAA Issuer component. It's the first function out of 2 in order to issue a DAA Creden-
       tial for a TCG Platform. It assumes that the endorsement key and its associated credentials are from a genuine and valid TPM. (Verification
       of the credentials is a process defined by the TCG Infrastructure WG.)

PARAMETERS

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

   issuerAuthPK
       The issuerAuthPKh parameter is the root authentication (public) key of DAA Issuer.

   issuerKeyPair
       The issuerKeyPair parameter is the handle of the main DAA Issuer key pair (private and public portion).

   identityProof
       The identityProof parameter is the structure containing endorsement, platform and conformance credential of the TPM requesting the DAA Cre-
       dential.

   capitalUprimeLength
       The capitalUprimeLength parameter is the length of capitalUprime which is .

   capitalUprime
       The capitalUprime parameter is U'.

   daaCounter
       The daaCounter parameter is the DAA counter.

   nonceIssuerLength
       The nonceIssuerLength parameter is the length of nonceIssuer (20 bytes).

   nonceIssuer
       The nonceIssuer parameter is the nonce of the DAA Issuer.

   authenticationChallengeLength
       The authenticationChallengeLength parameter is the length of authenticationChallenge (256 bytes - DAA_SIZE_NE1).

   authenticationChallenge
       The authenticationChallenge 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 TPM.

   joinSession
       The joinSession parameter is the structure containing the DAA Join session information.

RETURN CODES

       Tspi_DAA_IssueInit 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_IssueInit conforms to the Trusted Computing Group Software Specification version 1.2
