I don't really know much about the topic, but... How about using specialized, external hardware for each instance of crypto calculations?

- mardurhack 11y agoThere are some architectural question marks. Will this device be shared among the VMs? If so timing might be a clue on what's happening inside. It is definitely not an easy problem to solve.
- jgome 11y agoI'm thinking about, say, a big array of cheap, powerful-enough dedicated ARM/MIPS CPUs, used on-demand, one for each VM.
- mardurhack 11y agoConsidering multiple VMs share the same CPU, at times, I don't see it as a very convenient solution unless marketed as a "premium" package which very few will purchase given that these "attacks" are not that easy to carry out.
