Fault Attacks Sensitivity of Public Parameters in the Dilithium Verification

ePrint Report: Fault Attacks Sensitivity of Public Parameters in the Dilithium Verification

Andersson Calle Viera, Alexandre Berzati, Karine Heydemann

This paper presents a comprehensive analysis of the verification
algorithm of the CRYSTALS-Dilithium, focusing on a C reference
implementation. Limited research has been conducted on its susceptibility
to fault attacks, despite its critical role in ensuring the scheme’s security.
To fill this gap, we investigate three distinct fault models - randomizing
faults, zeroizing faults, and skipping faults - to identify vulnerabilities …
