Attacks involving faults (such as laser-induced, electromagnetic injection, or purely software-based) pose a severe threat to all embedded systems. Glitches in the power supply of components constitute a low-cost yet powerful method of attack for all embedded components. Despite some recent articles [1], few people are working on this topic, even though many optimizations can be made to improve the efficiency of attacks and quickly discover new exploitation paths. Using our glitch testing platform (as shown in the figure above and further explained in reference [2]) on standard microcontrollers, we propose to develop new glitch attack techniques, including the rapid search for the optimal pulse shape, the implementation of high-frequency glitches, and the enhancement of exploitability. The internship will unfold in several stages: -       Getting familiar with the setup and attack targets. -       Implementation of high-frequency glitches. -       Optimized parameter search. -       Implementation of a realistic attack scenario for the final demonstration.
