TEEs don't work, period. FHE does (ok, it's much slower for now).

- LPisGood 1y agoWhy do you say TEEs don’t work at all?
- treyd 1y agoTEEs, as they're marketed, requires a true black box. True black boxes do not exist, as a property of the rules of our universe. You can ALWAYS break them, it's just a matter of cost, even assuming they're perfectly designed and have no design/implementation flaws. And they're often not perfectly designed, sometimes requiring no physical hardware tampering.
- rossjudson 1y agoThe point of security efforts is to make an attacker's life harder, not to construct perfect defenses (because there's no such thing, as you've noted). TEEs make attacker's lives harder. Unless you can find a way to make your interposer invisible and undetectable, the value is limited.
- fpoling 1y agoQuantum mechanics with its non-copy property implies that a true black box can be created.
