Unboxing The White Box: Practical Attacks Against Obfuscated Ciphers

by Eloi Sanfelix Job de Haas Cristofaro Mune WhiteBox Cryptography (WBC) aims to provide software implementations of cryptographic algorithms that are resistant against an attacker with full access to the internals. Therefore, the key must remain secure even if the attacker is able to inspect and modify the execution of the cryptographic algorithm. This is often referred to as security in the WhiteBox In a vanilla implementation of a cryptographic algorithm, access to intermediate res
