Fault Injection

What is a Hardware Fault Injection?

A hardware fault injection exploits a physical disruption, mostly ephemeral, to create a logical error. When the logical fault is exploitable, an attacker may severely harm a system. There are different ways to create such a physical disruption: laser fault injection, near field electromagnetic fault injection or power glitching.

What is Laser Fault Injection by eShard ?

In a close partnership with ALPhANOV, the Laser Fault Injection tool combines ALPhANOV’s excellence in laser and optic systems, together with eShard’s scientific platform.

The resulting solution allows the implementation of Laser Fault Injections at the state-of-the-art.

βœ… Simple or double fault injection laser. The smallest and most powerful spot of the industry.

βœ… Different laser sources, with a focus on near infrared for back-side.

βœ… Back-side imaging with a unique system allowing chip and laser observation while pulsing.

βœ… Get further with extra features, such as spot size parameter, tip tilt table, etc.

βœ… The software suite to control the equipments and manage chip characterization

βœ… The software suite to manage fault injection campaigns, process faulty behaviours and exploit them (eg: DFA)

What is EMFI Electromagnetic Fault Injection tools by eShard?

At eShard, we have developed our own technology to inject near field electromagnetic pulses. We designed dedicated EMFI probes to inject faults in modern devices, such as SoC (System on Chip) with recent technologies.

βœ… Sets of injection probes with varying size, inductance and transmittance characteristics

βœ… Adapted to commercial pulsers

βœ… Hardware bench for X, Y and Z automated translations

βœ… The software suite to control the equipments and manage chip characterization

βœ… The software suite to manage fault injection campaigns, process faulty behaviours and exploit them (eg: DFA)

Training program

Ecosystems move fast, so do the cybersecurity challenges. Your team must remain up-to-date and master the last security threats because your business and your customers are at stake.
Intermediate
Differential Fault Analysis on symmetric algorithms
Coach: Guillaume Vinet
With this module, you will learn about the main Differential Fault Attacks on AES. You will get familiar with the Piret & Quisquater DFA targetting the AES final rounds and the Kim & Quisquater DFA targeting the AES key schedule. During this training, you will learn how to compute differentials, characterize faults and recover a secret key from faulty AES outputs.

Intermediate
Laser Fault Injection with esDynamic
Coach: Guillaume Vinet
Using the [esDynamic](https://eshard.com/esdynamic) platform, you will learn how to control ALPhANOV's laser equipment and implement a fault campaign. You will learn how to perform a multi-dimensional scanning, and log results of your campaing. You will learn how to use the delay generator and setup your injection trigger to precisely inject a fault during the device execution. During the practice session, you will get the opportunity to inject a successful laser fault on a device.
Starter Kit Chip Security by eShard

Starter Kits

Fault injection may turn out to be a powerful means to compromise a device. The ability to secure a system against fault injection depends on the ability to apprehend the technique. It requires practical expertise. Starter kits have been designed to provide the knowledge of practical attacks on recent use cases. They show the complexity of identifying a weakness. Starter kits provide a set of hardware and knowledge to create an in-house reference for practical attacks. For your internal knowledge and training purposes.

  • Hardware kits on modern SoC (System on Chip)
  • Each step of the practical fault injection is described in detail
  • From the bench setup to the final exploitation exhibiting the secret

Grow your Expertise

Getting up to speed in fault injection requires knowledge of the technique and practical experience. Together with ALPhANOV, a dedicated training was designed to cover all aspects of professional laser fault injections. Delivered on site in ALPhANOV’s training centre, this training will cover both the theoretical and practical aspects of a successful fault injection on a real device.

  • Understanding the laser system and the related safety
  • Setting up a laser fault injection campaign to characterize a device
  • Creating a heatmap and exploiting the results
