Tspi_DAA_IssueSetup - generate a DAA Issuer public and private key

 #include <tss/tss_typedef.h>  #include <tss/tss_structs.h>  #include <tss/tspi.h>  "TSPICALL Tspi_DAA_IssueSetup("  " TSS_HDAA " hDAA ","  " UINT32 " issuerBaseNameLength ","  " BYTE* " issuerBaseName ","  " UINT32 " numberPlatformAttributes ","  " UINT32 " numberIssuerAttributes ","  " TSS_HKEY* " keyPair ","  " TSS_DAA_PK_PROOF** " identity_proof  ");" 

\Tspi_DAA_IssueSetup is part of the DAA Issuer component. It defines the generation of a DAA Issuer public and secret key. Further it defines the generation of a non-interactive proof (using the Fiat-Shamir heuristic) that the public keys were chosen correctly. The latter will guarantee the security requirements of the platform (respectively, its user), i.e., that the privacy and anonymity of signatures will hold. The generation of the authentication keys of the DAA Issuer, which are used to authenticate (main) DAA Issuer keys, is not defined by this function. 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 issuerBaseNameLength parameter is the length of the issuerBaseName. The issuerBaseName parameter is the unique name of the DAA Issuer. The numberPlatformAttributes parameter is the number of attributes that the Platform can choose and which will not be visible to the Issuer. The numberIssuerAttributes parameter is number of attributes that the Issuer can choose and which will be visible to both the Platform and the Issuer. The keyPair parameter is the handle of the main DAA Issuer key pair (private and public portion). The publicKeyProof parameter is the Handle of the proof of the main DAA Issuer public key.

Tspi_DAA_IssueSetup 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.
