Collide+Power: The Evolution of Software-based Power Side-Channels Attacks

Power side channels exploit leakage that is fundamentally a result of how we build processors. Over the recent years, these attacks evolved to target general-purpose desktop and server CPUs purely from software. In this talk, we explore this evolution to its most recent addition: Collide Power, a novel technique to exploit the fundamental way we share components in modern general-purpose CPUs. In contrast to previous work, Collide Power does not target specific programs or algorithms but the underlying CPU hardware. This advance in software-based power side channels echoes the discovery of Meltdown and Spectre — where similarly, the underlying hardware provided unforeseen attack possibilities....
