DESCRIPTION

       Tspi_TPM_DAA_JoinInit  is the first out of 3 functions to execute in order to receive a DAA Credential. It verifies the keys of the DAA Is-
       suer and computes the TPM DAA public key.

PARAMETERS

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

   hTPM
       The hTPM parameter is the handle to the TPM object.

   issuer_pk
       The issuer_pk parameter is the of the DAA Issuer public key.

   issuer_authentication_PKLength
       The issuer_authentication_PKLength parameter is the length of the array of issuerAuthPKs.

   issuer_authentication_PK
       The issuer_authentication_PK parameter is an array of RSA public keys (key chain) of
	the DAA Issuer used to authenticate the DAA Issuer public key. The size of the modulus must
	be TPM_DAA_SIZE_issuerModulus (256).

   issuer_authentication_PK_signaturesLength
       The issuer_authentication_PK_signaturesLength parameter is the length of the array of
	issuerAuthPKSignatures. It is equal to issuerAuthPKsLength. The length of an element of the
	array is TPM_DAA_SIZE_issuerModulus (256).

   issuer_authentication_PK_signatures
       The issuer_authentication_PK_signatures parameter is the array of byte arrays representing
	signatures on the modulus of the above key chain (issuerAuthPKs) in more details, the array has
	the following content (S(K[1],K[0]),S(K[2],N[1]),..S(K[ k ],K[n-1]), S(TPM_DAA_ISSUER,K[ k ])),
	where S(msg,privateKey) denotes the signature function with msg being signed by the privateKey.

   capital_UprimeLength
       The capital_UprimeLength parameter is the length of capitalUprime which is ln/8. ln is defined as the size of the RSA modulus (2048).

   capital_Uprime
       The capital_Uprime parameter is U'.

   identityProof
       The identityProof parameter is a structure containing the endorsement, platform and conformance
	credential.

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

RETURN CODES

       Tspi_TPM_DAA_JoinInit returns TSS_SUCCESS on success, otherwise one of the following values is returned:

       TSS_E_INVALID_HANDLE
	      Either the DAA or the TPM handler is not valid.

       TSS_E_BAD_PARAMETER

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       TSS_E_DAA_ISSUER_KEY_ERROR

CONFORMING TO

       Tspi_TPM_DAA_JoinInit conforms to the Trusted Computing Group Software Specification version 1.2
