Theoretical differential fault attacks on FLIP and FiLIP

ePrint Report: Theoretical differential fault attacks on FLIP and FiLIP

Pierrick Méaux, Dibyendu Roy

In this article, we examine Differential Fault Attacks (DFA) targeting two stream ciphers, FLIP and FiLIP. We explore the fault model where an adversary flips a single bit of the key at an unknown position. Our analysis involves establishing complexity bounds for these attacks, contingent upon the cryptographic parameters of the Boolean functions employed as filters and the key size.
Initially, we demonstrate how the concept …
