SoK: Fault Injection Attacks on Cryptosystems

Abstract

Fault injection attacks are a powerful technique that intentionally induces faults during cryptographic computations to leak secret information. This paper provides a survey of fault attack techniques on different cryptosystems. The fault attack consists of two main components: fault modeling, which examines methods for injecting faults in a target device, and fault analysis, which analyzes the resulting faulty outputs to deduce secrets in each cryptosystem. We first categorize various fault attack methods by fault model and fault analysis.We then give examples of the various fault attacks on symmetric key cryptosystems and public key cryptosystems. This paper aims to provide a background on fault attack research and directions for further study on securing real-world cryptosystems against fault injection attacks.
