What is a Side Channel Attacks?

Side Channel attacks are the fruit of more than 20 years of research. As a result, most of the cryptographic algorithms and their implementations into chips are subject to it. Our Side Channel Analysis tools include solutions for Hardware, Software and physical attacks on hardware products.

What is required for a Side Channel Analysis?

Securing a hardware against Side Channel attacks requires the tester to tackle three main points:

  • A measurement bench with the ability to collect valuable information,
  • A software platform able to manage heavy computation with flexibility,
  • Hands-on expertise on and knowledge of multiple variants of attacks.

We offer all the necessary side channel tools to keep the security of your hardware in check.

Side channel software platform

Why eShard software solution for a Side Channel Analysis?

It is necessary to perform the whole side channel experimental flow on the same platform from the data collection to the statistical analyses. esDynamic is the scientific platform that offers the perfect technology to power side channel analyses with flexibility on all algorithms (AES, RSA, ECC, ...) and the ability to compute high volumes of data.

  • Manage the trace collection from the device and the lab equipment
  • Create cartography of the leakage detection
  • Perform data processing, such as trace alignment
  • Search leakages in the data set (T-Test)
  • Process statistics with efficient computation (DPA, CPA, MIA, ANOVA ..) in 1st or higher order

Side channel expertise security

Expertise module extension: theoretical expertise

Side-channel is the fruit of more than 20 years of research. We developed a specific expertise material to cover

  • the attack techniques (deep learning, Scatter, lattice, ..) or,
  • the attacks applied to algorithms (Post Quantum Cryptography, LightWeight Cryptography, SMx).

With esDynamic and the specialized modules, we reconcile the know and the how into a unique know-how technical and dynamic content: attacks are described, can be replayed and adapted to your use case.

  • Catalogues of attack: the knowledge explained and the attack techniques fully implemented
  • Specialized libraries optimised for fast computation
  • Reference data sets
Starter Kit Chip Security by eShard

Use cases extension: hands-on expertise

Practical expertise can make the difference when successfully undertaking a side channel attack. Initially, Side Channel Analysis only targeted Smart Cards, but is now increasingly targeted towards complex System on Chip (SoC) devices.

Our Starter Kit is a real use case demonstrating all practical aspects of a successful side channel analysis on recent devices: from the bench setup to the secret key exhibition.

The hardware kit is delivered with the data traces and the dynamic content. And our catalog includes different use cases, including:

  • Side channel attack targeting an hardware implementation of an AES
  • Side channel attack targeting an ECDSA

Infrastructure extension: parallel and distributed computing

Side-channel analyses often demand substantial computing power, arising from

  • the large data sets (ranging into the millions of data traces) or
  • the depth of statistical investigations (such as high-order analysis or deep learning).

The esDynamic platform is exceptionally adaptable, designed to seamlessly integrate with GPU parallelism or distributed computing across CPUs or multiple machines. Its scalable infrastructure can be customized to meet diverse requirements. The Fast Computing (FCx) extension is specifically engineered to harness parallel or distributed computing, incorporating advanced statistical methods for unparalleled performance.
