- JoachimSchipper 9y agoThat gives the correct flavour, but note that we use a different side-channel than timing - this is really a hardware attack, so we e.g. pick up 0->1 transitions in the address bus.
- buu700 9y agoAh, thanks for clarifying that; I'd just assumed it was timing from a quick skim.
