> Except... if the attacker is on your box, they could simply take a copy of the enclave! Yeah this is the part I'm assuming isn't possible, perhaps out of ignorance. I believe that, at least in SGX's case, this is possible because SGX exposes per-CPU keys, and the ability to derive secrets from those keys. So if you moved the enclave (I actually have no idea how moving an enclave works either fwiw) it would no longer be valid. But yeah, this all kinda goes to "I have no idea what I'm doing with enclaves" lol, this is just the use case I have - keeping a secret stored in one so that an attacker can not exfiltrate it. |
