Started to scratch my head that is it really an issue that any enclave can provision in the end? Direct quote from your first response: "In particular, the ability to run enclaves with the provisioning bit set is somewhat sensitive, since it effectively allows access to a stable fingerprint of the system." As can be seen from the key derivation table this does not exactly hold so you should refine your original argument before we can consider any type of change. I just don't see what it is so wrong for any enclave to be able to tell that it really is an enclave. /Jarkko
