Fault Attacks and Countermeasures

Contact: Michael Gruber

Fault-attacks represent a major threat to the security of cryptographic embedded devices. By actively perturbing the activity of a device, data dependent faulty behaviour can be observed.

The information leaked by a faulty computation can be exploited using several methods, based on analytical, statistical approaches.

Research topics:

Theoretical Fault Attacks

  • Differential Fault Attacks
  • Statistical Fault Attacks
  • Algebraic Fault Attacks
  • Implementation of countermeasures against fault attacks

Practical Fault Attacks

  • Electromagnetic Fault Injection
  • Forward Body Bias Injection
  • Localized Optical (low-cost) Fault Attacks

Course Offered:
