The Fault Attack Jungle - A Classification Model to Guide You

Abstract

For a secure hardware designer, the vast array of fault attacks and countermeasures looks like a jungle. This paper aims at providing a guide through this jungle and at helping a designer of secure embedded devices to protect a design in the most efficient way. We classify the existing fault attacks on implementations of cryptographic algorithms on embedded devices according to different criteria. By doing do, we expose possible security threats caused by fault attacks and propose different classes of countermeasures capable of preventing them.
