Java Card Combined Attacks with Localization-Agnostic Fault Injection

In this paper, we present a paradigm for combined attacks on Java Cards that lowers the requirements on the localization precision of the fault injection. The attack relies on educated objects allocation to create favorable memory patterns that raise the chances of success of the combined attack. In order to maximize the probability of successful injection, we determine the optimal parameters depending on the physical properties of the targeted platform. Finally, we demonstrate the e ciency of our approach through fault injection simulation.
