The silicon industry has lately been focusing on side channel attacks, that is attacks that exploit information that leaks
from the physical devices. Although different countermeasures to thwart these at- tacks have been proposed and implemented
in general, such protections do not make attacks infeasible, but increase the attacker’s experimental (data acquisition) and
computational (data processing) workload beyond reasonable limits. This paper examines different ways to attack devices featuring
random process interrupts and noisy power consumption.
