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, UINT32 daaCounter, UINT32* nonceIssuerLength, BYTE** nonceIssuer, UINT32* authenticationChallengeLength, BYTE** authenticationChallenge, 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 SEE ALSO

Tspi_TPM_DAA_Sign - creates a DAA Signature that proofs ownership of the DAA Credential SYNOPSIS
#include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> TSS_RESULT Tspi_TPM_DAA_Sign( TSS_HDAA hDAA, TSS_HTPM hTPM, TSS_HKEY hDaaCredential, TSS_DAA_SELECTED_ATTRIB revealAttributes, UINT32 verifierBaseNameLength, BYTE* verifierBaseName, UINT32 verifierNonceLength, BYTE* verifierNonce, TSS_DAA_SIGN_DATA signData, TSS_DAA_SIGNATURE* daaSignature ); DESCRIPTION
Tspi_TPM_DAA_Sign creates a DAA Signature that proofs ownership of the DAA Credential and includes a signature on either a public AIK or a message. If anonymity revocation is enabled, the value Nv is not provided in the clear anymore but encrypted under the public key of anonymity revocation authority, a trusted third party (TTP). Thus the DAA Verifier cannot check for revocation or link a transaction/signa- ture to prior ones. Depending on how is chosen, the protocol either allows implementing anonymity revocation (i.e., using the DAA Issuer's long-term base name as the DAA Verifier's base name ), or having the TTP doing the linking of different signatures for the same DAA Veri- fier (i.e., using the DAA Verifier's base name ). 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. hDaaCredential The hDaaCredential parameter is the Handle of the DAA Credential. revealAttributes The revealAttributes parameter is the attributes which the credential owner wants to reveal to the DAA Verifier. verifierBaseNameLength The verifierBaseNameLength parameter is the Length of verifierBaseName. verifierBaseName The verifierBaseName parameter is the base name chosen by the DAA Verifier. If it equals to null, the platform chooses a random base name. verifierNonceLength The verifierNonceLength parameter is the length of verifierNonceName (20 bytes). verifierNonce The verifierNonce parameter is the nonce created by the DAA Verifier. signData The signData parameter is the handle of the received DAA Credential. daaSignature The daaSignature parameter is the DAA signature containing the proof of ownership of the DAA Credential, as well as a signature on either an AIK or a message. RETURN CODES
Tspi_TPM_DAA_Sign 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. CONFORMING TO
