Can't intel and amd just change how long a core stays at a turbo frequency to mitigate this? I.e.: if it scales up by 1hz, it can't scale down by that much until N number of cycles.
- zgs 4y agoThis would add noise to the measurements which should cause an exploit to take longer but it wouldn't prevent the exploit.
- _8j50 4y agoPardon my ignorance but why wouldn't sufficient noise make it practically impossible to timing attacks. Very short secret material being processed multiple times?
