Abstract

In this note, we describe an attack against the ANSSI Side-Channel Analysis Database (ASCAD), which recovers the full key using the leakage of a single masked block cipher execution. The attack uses a new open-source Side-Channel Analysis Library (SCALib), which allows running the leakage profiling and attacking in less than 5 minutes. It exploits well-known techniques, yet improves significantly over the best known attacks against ASCAD. We conclude by questioning the impact of these experimental findings for side-channel security evaluations.
