Abstract: With an ever growing number of devices connecting to each other and to the Internet (usually subsumed under the ”Internet-of-Things” moniker), new challenges arise in terms of keeping these devices safe, secure and usable. Against better judegment, a large number of such devices never gets updated after being deployed, be it from negligence, inconvenience or sheer technical challenges. And all that while a plethora of valid approaches already exists for secure wireless remote update processes for such devices. In this work, we present another approach to solve this problem, with a special focus on the ease of integration into existing systems: we try to provide the absolute bare minimum to enable a secure over-the-air update process, analyze the security of this approach, and evaluate the performance impact of the implementation. We show that our solution can deal with nearly 80% of the identified threats, with a negligible impact on practical performance in terms of processing power and energy consumption. (More)
