Abstract:
Automobiles nowadays consist of multiple Electronic Control Units (ECUs) and bus systems. Attacks on these critical infrastructure elements have increased a lot over the last years, especially since remote exploitation is possible due to wireless connectivity. Most of these attacks targeted standard services implemented in cars. These services, e. g., allow the activation of the headlights or turning of the steering wheel via the parking assist. All these services have to be secured so they can only be executed when it is safe to do so. These checks for a safe state are plausibility checks, which nowadays only utilize the vehicle speed. In this paper we motivate the need for other values that have to be authentic and integrous. We want to utilize immanent signals, derived from hard wired sensors, for each ECU that utilizes plausibility checks.
