DESCRIPTION

27       Tspi_DAA_IssueCredential  is part of the DAA Issuer component. It's the
28       last function out of 2 in order to issue a DAA  Credential  for  a  TCG
29       Platform.  It  detects  rogue  TPM according to published rogue TPM DAA
30       keys.  This is an optional function and does not require  a  TPM  or  a
31       TCS.

PARAMETERS

35   hDAA
36       The hDAA parameter is used to specify the handle of the DAA object.
37
38   attributesIssuerLength
39       The attributesIssuerLength parameter is the length of the attributesIs‐
40       suer array, which is determined by the DAA Issuer public key (li).  The
41       length of a single attribute is if/8.
42
43   attributesIssuer
44       The attributesIssuer parameter is the array of attributes to be encoded
45       into the DAA Credential visible to the DAA Issuer .
46
47   credentialRequest
48       The credentialRequest parameter is the credential request of the  Plat‐
49       form,  it  contains the blinded DAA public key of the platform on which
50       the DAA Issuer will issue the credential the blinded attributes  chosen
51       by the Platform.
52
53   joinSession
54       The joinSession parameter is the structure containing the DAA Join ses‐
55       sion information.
56
57   credIssuer
58       The credIssuer parameter is the structure containing the DAA Credential
59       issued  by  the  DAA Issuer, the proof of correctness of the credential
60       and the attributes chosen by the DAA Issuer.

71
72       TSS_E_DAA_AUTHENTICATION_ERROR
73              The authentication proof of the TPM is incorrect.
74
75       TSS_E_DAA_PSEUDONYM_ERROR
