Re: [TrouSerS-users] Question about attestation.. (part-2)

Hi All, (Hal/Kent, Abhishek, et al)
 
I have a follow-up question on the email thread with the above subject-line.
https://sourceforge.net/mailarchive/message.php?msg_id=417111.42335.qm%40web43142.mail.sp1.yahoo.com
 
I am at a stage where I am able to obtain an AIK (generate and validate by Privacyca.com).  After successfull 'ActivateIdentity', I am saving the keyblob as a file.
 
But I am not sure how I can re-load that key back.  I have been able to reload other 'created RSA keys under the SRK', but the one generated for the AIK (using TSS_KEY_TYPE_IDENTITY flag) loads fine but fails TPM_Quote operation when used.
Return an error value of 0x01.
Could it be because of the key flags doesn't have 'TSS_KEY_TYPE_SIGNING'?
 
Has anyone had better success with 'registerkey' in the TSS persistant storage?
 
I am urgently looking for either one of the way to save, load and perform a TPM_Quote, for a demo.
Any pointers as to which methods has worked and what are the steps, would be appriciated.
 
-regards,
Jithendra
