DESCRIPTION
       Tspi_DAA_VerifySignature  is  part  of the DAA Verifier component. It's the last function out of 2 in order to verify a DAA Credential of a
       TCG platform. It verifies the DAA Credential and detects public rogue TPMs.  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.

   daaSignature
       The  daaSignature parameter is the DAA signature contains proof of ownership of the DAA Credential, as well as a signature on either an AIK
       or a message.

   hPubKeyIssuer
       The hPubKeyIssuer parameter is the handle of the DAA public key of the DAA Issuer of the credential.

   signData
       The signData parameter defines what data is signed (AIK or message).

   attributesLength
       The attributesLength parameter is the Length of attributes array that is determined by the DAA Issuer public key (lh+li). The length  of  a
       single attribute is lf/8.

   attributes
       The attributes parameter is the array of attributes which the DAA Credential owner reveals.

   nonceVerifierLength
       The nonceVerifierLength parameter is the length of nonceVerifier (20 bytes).

   nonceVerifier
       The nonceVerifier parameter is the nonce that was computed in the previous function (Tspi_VerifyInit).

   baseNameLength
       The baseNameLength parameter the length of the baseName.

   baseName
       The baseName parameter is the base name that was chosen for the DAA Signature.

   isCorrect
       The isCorrect parameter denotes if the verification of the DAA Signature was successful.

RETURN CODES
       Tspi_DAA_VerifySignature returns TSS_SUCCESS on success, otherwise one of the following values is returned:

       TSS_E_BAD_PARAMETER

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       CONFORMING TO

       Tspi_DAA_VerifySignature conforms to the Trusted Computing Group Software Specification version 1.2
