Intel to Build Silicon for Fully Homomorphic Encryption
One of the main drawbacks of FHE is that it usually leaks some details of your data. E.g., if you do a multiplication of two (encrypted) values, an attacker can memorize the input and output. Since for most useful applications (eg ML) your computations must be deterministic, an attacker can build up a table of calculations. Once this is filled a bit, he can use that with some heuristics to estimate the data.<p>The problem here is that it can be very difficult to prove that an application using FHE is really secure against leaking information.<p>I guess Intel will just do some marketing a la "it's encrypted, thus is safe" BS that semi- or non-technical managers will buy to put a checkmark on their security checklists.
