Tspi_DAA_VerifyInit - creates a challenge for the TCG platform

 #include <tss/tss_typedef.h>  #include <tss/tss_structs.h>  #include <tss/tspi.h>  "TSPICALL Tspi_DAA_VerifyInit("  " TSS_HDAA " hDAA ","  " UINT32* " nonceVerifierLength ","  " BYTE** " nonceVerifier ","  " UINT32* " baseNameLength ","  " BYTE** " baseName  ");" 

\Tspi_DAA_VerifyInit is part of the DAA Verifier component. It's the first function out of 2 in order to verify a DAA Credential of a TCG platform. It creates a challenge for the TCG platform. This is an optional function and does not require a TPM or a TCS.

The hDAA parameter is used to specify the handle of the DAA object. The nonceVerifierLength parameter is the length of the nonceVerifier. The nonceVerifier parameter is the challenge for the platform. The baseNameLength parameter is the length of the baseName. The baseName parameter is the base name that was chosen for the DAA Signature.

Tspi_DAA_VerifyInit 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.

Tspi_DAA_VerifyInit conforms to the Trusted Computing Group Software Specification version 1.2

Tspi_DAA_IssuerKeyVerification(3)
