To enable autonomous driving, driver assistance systems need a lot of information from different sources. Data from the immediate vicinity of the vehicle together with information provided via the Internet is processed in the operational control of the car. For example, route planning of e-vehicles must be adapted according to information about charging infrastructure. Currently, a subset of this information is already available offline in the vehicle. Another example of the necessary integration of a vehicle into the Internet are over the air software updates. In order to close vulnerabilities in the control software, these must be regularly supplied with updates. Time-accurate updates must be recorded online and linked to the appropriate hardware components. The integration of vehicles into the Internet requires its own security concepts.
