Re: [tor-talk] Practical deanonymization using CPU load covert channels
Ping latency decreases when CPU usage is high
an adversary can influence CPU usage to transmit data
I can confirm that disabling c-states does completely
prevent this attack.
providing an option in Tails to disable c-states,
perhaps in the form of a GRUB entry
Up front like that would be okay but fragments the settings a bit; like
Tails Greeter is the most suitable place for such a setting; in the
'Additional Settings' section.
Articulating this attack in such a small place can become a challenge (:
Would disabling ping replies do the same thing, because that may be more
effective in communicating the concern ?
