This post is a noob-friendly introduction to whiteboxes along with the presentation and explanation of a (not-new) collision-based attack. The attack is demonstrated against a public whitebox, using QBDI to instrument and analyze the target in order to produce traces of execution.

With the Differential Computation Analysis (DCA) presented at CHES 2016, we have shown that side-channel techniques developed to break hardware cryptographic implementations can be adapted successfully to break white-box implementations. In this post, we will explore another class of hardware attacks: fault injections and how to apply them on white-box implementations.
