FHE Can't Save Us: The Case Against Cryptographic AI Boxing
tl;dr - Cryptographic containment of AI (using techniques like Fully Homomorphic Encryption to mathematically guarantee a model's behaviour before decrypting it) is theoretically elegant. But the computational overhead (1,000x to 1,000,000x relative to standard operations) makes it practically infeasible, likely for the foreseeable future. Even setting aside the cost, the...
