**1.2 A new approach: real-time IoT and cybersecurity**

ADS-based mobility requires a secure, uninterrupted connection between all traffic participants. It therefore relies on a smooth and fast flow of data for each individual information chain between all relevant participants. This also means that these chains must be protected from attack. All possible attack vectors must be secured, regardless of the point of attack. At the same time, it must be ensured that the acquisition and response times of all data in the relevant information chains are reliable, deterministic and predictable. A suitable computing infrastructure with cybersecurity—QoS (Quality of Service) and real-time IoT capabilities—is therefore required [3].

The ADS system must ensure both cybersecurity and real-time IoT capabilities across all information chains of the entire system. While these requirements may seem contradictory at first, it is essential to perform the necessary analysis during the design phase to develop concepts, architectures and strategies that resolve this contradiction. By doing so, we can avoid the costly and often unattainable process of implementing security and real-time capabilities in an ADS after the fact.
