BasicBlocker: ISA Redesign to Make Spectre-Immune CPUs Faster

Year: 2021

Type: conference-paper

Abstract: Recent research has revealed an ever-growing class of microarchitectural attacks that exploit speculative execution, a standard feature in modern processors. Proposed and deployed countermeasures involve a variety of compiler updates, firmware updates, and hardware updates. None of the deployed countermeasures have convincing security arguments, and many of them have already been broken.
