Title:
Towards Explainable Side-Channel Leakage: Unveiling the Secrets of Microarchitecture
Authors: Ischa Stork, Vipul Arora, Łukasz Chmielewski, Ileana Buhan
Abstract:We explore the use of microbenchmarks, small assembly code snippets, to detect microarchitectural side-channel leakage in CPU implementations. Specifically, we investigate the effectiveness of microbenchmarks in diagnosing the predisposition to side-channel leaks in two commonly used RISC-V cores: Picorv32 and Ibex. We propose a new framework that involves diagnosing side-channel leaks, identifying leakage points, and constructing leakage profiles to understand the underlying causes. We apply our framework to several realistic case studies that test our framework for explaining side-channel leaks and showcase the subtle interaction of data via order-reducing leaks.
