Cryptographic collision attack
WebJul 12, 2024 · An impersonation attack is when an adversary can successfully claim an identity that he doesn't possess, and pass authentication (i.e. he can pretend to be another person in the system). Many authentication protocols rely on verifying some cryptographic data, if the cryptographic data can be forged, then authentication will admit the wrong … WebSince the introduction of white-box cryptography, a number of white-box implementations of the Chinese SM4 block cipher standard have been proposed, and all of them have been attacked based on Billet et al.’s attack. In this study, we show that collision-based attack can work more efficiently on Shi et al.’s white-box SM4 implementation ...
