First time posting, thanks in advance for any help. I am using Trousers
for Windows-which I believe is a port of 0.3.4-using a Broadcom 7.13
TPM. My code is currently an amalgamation from privacyCA and trousers
test utilities.
I am making a series of success calls leading up to and including
Tspi_TPM_CollateIdentityRequest; after which I am immediately calling
Tspi_Key_LoadKey and Tspi_TPM_ActivateIdentity-both calls fail (I am
excluding all the PrivacyCA stuff form the identity.c example).
Tspi_Key_LoadKey returns the dreaded TSS_E_FAIL response, and
Tspi_TPM_ActivateIdentity returns a TSS_E_KEY_NOT_LOADED (presumably
because the LoadKey failed). My question is do I really need to be
calling Tspi_Key_LoadKey and Tspi_TPM_ActivateIdentity if all I want is
to create an AIK for the ultimate purpose of obtaining a quote?
Next question:
Assuming I am successfully creating an AIK, how do I get a handle to the
AIK? I am trying two methods, both of which fail.
Method 1:
Get and save the AIK blob after running CollateIdentity. I have tried
saving blobs returned from Tspi_GetAttribData (using both the
TSS_TSPATTRIB_KEYBLOB_BLOB and TSS_TSPATTRIB_KEYBLOB_PUBLIC_KEY
options), and using the Tspi_Context_LoadKeyByBlob call. This attempt
results in a TSS_E_FAIL.
Method 2:
Get a list of keys and their UUIDs by using the
Tspi_Context_GetRegsteredKeysByUUIID call; followed by a 1)
Tspi_Context_GetKeyByUUID, 2) policy assignment, and 3) a call to
Tspi_Key_LoadKey. I am getting a TSS_E_INTERNAL_ERROR when calling
GetRegsteredKeysByUUIID. Is this even a valid approach?
