    Attacking SoCs by side-channel or laser fault injection: a Graal's quest

    To make a successful side-channel or laser fault injection analysis on a SoC, you need to overcome a number of obstacles. This talk provides some illustrations based on practical experiences on real mobile or IoT devices. More particularly, the focus is made on integrated AES with the aim to extract the secret key. It highlights where technical challenges are and some methods to tackle them: creating the conditions of measurements by tuning the SoC device, manage the trigger, facing a complex execution, explore and find the optimal set of parameters, including the location through the vast surface of the die, and finally successfully implement the attack to extract the secret key. The quest is rarely simple, but at the end the result may be worthwhile, since the secret key is exposed.
