Secure Cache Designs: The State of the Art and Beyond

Activity: Talk or presentationTalk at conference or symposiumScience to public

Description

In recent years, the advent of microarchitectural attacks has brought with it a renewed interest in secure cache designs. The prominent strategies that have emerged in secure cache designs to mitigate side-channel attacks are randomization or partitioning. Following initial designs, other works have shown that even these improved designs are limited in the face of more advanced attacks, starting a theoretical (cache) arms race.

In this talk, we give an overview of traditional and secure caches designs, as well as their respective attacks. We outline the mechanisms of the most prominent designs and discuss their properties. We take a detailed look at which design assumptions were broken by new attacks and where designs may have had flaws to begin with. Finally, we present a new cache design that aims to avoid currently known attacks and sidestep the mechanisms on which they are built.
