Abstract:
The security of Internet of Things (IoT) devices relies on fundamentalconcepts such as cryptographically protected firmware updates. In this contextattackers usually have physical access to a device and therefore side-channel attackshave to be considered. This makes the protection of required cryptographic keysand implementations challenging, especially for commercial off-the-shelf (COTS)microcontrollers that typically have no hardware countermeasures. In this work, wedemonstrate how unprotecte...     »
