Side-channel attacks based on deep learning

Side-Channel Attacks are attacks against implementations of cryptographic algorithms. These attacks exploit physical properties of a device under attack. For example an attacker can measure the execution time or power consumption of a device while it executes a cryptographic algorithm.

Based on neural network, deep learning represents an active research in machine learning that allows producing automatic attacks requiring no a priori information on the underlying phenomenon. The purpose of this work is to shed new light on the capabilities of deep learning in side-channel attacks.

This work is in collaboration with RISCURE (www.riscure.com), a company working on security evaluation of embedded devices.

Speaker: Kostas Papagiannopoulos (Radboud University)

Title: Location-Based Side-Channel Analysis: from EM Experiments to Information-Theoretic Models

Abstract: In this talk we discuss a class of unconventional side-channel analysis, namely location-based attacks. We demonstrate the applicability of those attacks in ARM Cortex M4 processors and discuss possible attack modeling options via information theory.
