Poster : Side-Channel Finder for AVR

AVR microcontrollers [1] are widely used, e.g., in Internet of Things devices. Such devices are targets for attacks (e.g., the recent side-channel attack on smart lightbulbs [2]). In a side-channel attack, an attacker observes execution characteristics, e.g., time, from which he deduces information about a secret. Timing-side-channel attacks are particularly dangerous because they can be mounted remotely [3]. On this poster, we present our results [4] and ongoing work on timing-side-channel detection for AVR microcontrollers.
