A Single Trace Fault Injection Attack on Hedged CRYSTALS-Dilithium

ePrint Report: A Single Trace Fault Injection Attack on Hedged CRYSTALS-Dilithium

Sönke Jendral

CRYSTALS-Dilithium is a post-quantum secure digital signature algorithm currently being standardised by NIST. As a result, devices making use of CRYSTALS-Dilithium will soon become generally available and be deployed in various environments. It is thus important to assess the resistance of CRYSTALS-Dilithum implementations to physical attacks.
In this paper, we present an attack on a CRYSTALS-Dilithium implementation in hedged mode in ARM Cortex-M4 using fault injection. Voltage …
