Security and Verification in Computing

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.
