Thanks for the response David.  Do you then need the owner password to load
it, or only to create?  I also remember reading something somewhere that
TrouSerS currently has issues with owner evict keys, in fact I believe it
was a paper or similar that you wrote.

 

Regards,

You can store the key permanently in the TPM as an owner_evict key.

Hi All 

Is it possible to create a binding or signing key that doesn't require SRK
authorization and only PCR states?  I can see that when you create a new key
that you can state that it requires no authorization and only tie it to PCR
values, but it seems you still need the SRK to load the key into context.

 

Thanks,

Ceri
