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.The problem here is that it can be very difficult to prove that an application using FHE is really secure against leaking information.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.
