ECDSA White-Box Implementations: Attacks and Designs from CHES 2021 Challenge

2022 · IACR Transactions on Cryptographic Hardware and Embedded Systems

Despite the growing demand for software implementations of ECDSA secure against attackers with full control of the execution environment, scientific literature on ECDSA white-box design is scarce. The CHES 2021 WhibOx contest was thus held …

Fault Attacks on a Cloud-Assisted ECDSA White-Box Based on the Residue Number System

2023

Ahstract-White-box cryptography aims at protecting software implementations of cryptographic algorithms when the attacker has complete control over the execution environment. Since the early 2000's, white-box implementations of block ciphers have received great interest from the …
