What about side effects? Does eg timing of the computations leak data?
- jrockway 7y agoI would expect that all data processing by default leaks information via computation time. Some algorithms are intentionally designed to resist this; people that have gone to this effort will mention them. (A similar thing: assume something is not thread-safe unless the documentation mentions it's thread-safe.)
- rhindi 7y agoActually homomorphic encryption always ends up running as slow as the worse case, so you can’t do a sidechannel attack by looking at the computation time.
