Cryptanalysis of a white‐box SM4 implementation based on collision attack
IET Information Security, 2022 White‐box cryptography is to primarily protect the key of a cipher from being extracted in a white‐box scenario, where an adversary has full access to the execution environment of software implementation. Since the introduction of white‐box cryptography,

ECDSA White-Box Implementations: Attacks and Designs from CHES 2021 Challenge
Transactions on Cryptographic Hardware and Embedded Systems, 2022 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 to assess the
