Overview

This repo contains the MATLAB code for the paper "Improving side-channel analysis with optimal linear transforms" (CARDIS 2012). The paper and slides are available as PDF in this repo.

This code is quite old, so no warranties that it will run directly on your setup - you might have to tweak and update things. I tried it with MATLAB R2018b in 2019 and the simulation code was running fine. The code for the DPA v2 contest will definitely need proper paths and especially handling of the AttackWrapper.
