Definition
White-Box Cryptography captures the research topic that investigates how cryptographic primitives can be implemented in software in such a way that they remain robust against attacks from the execution environment.
Background
Traditionally, cryptographic primitives are designed to protect data and keys against black-box attacks. In such a context, an adversary has knowledge of the algorithm (Kerckhoffs’ Principle) and may examine various inputs to and outputs from the system, but has no access to the internal details of the execution of a key instantiated primitive. In contrast, in many applications this context might not be compliant. In particular, on computing platforms where an adversary might have access to the memory, intercept CPU calls, or even have access to the binary software implementation of a key instantiated cryptographic primitive and deploy debuggers and...
