Today, most smart cities and intelligent transport systems are implemented in a very centralized way: Sensors send their data to a central control center, where all data is processed at in the same place and control signals, for example for traffic signs are generated. This very centralized approach is not efficient and does not scale well.

In a city wide parking management system, the central server does not need to know which individual parking slots are available – all it needs to know is the occupancy of a parking site as a whole. Secure distributed system design. Therefore, a secure distributed system processing local data locally and only sending pre-processed data to a central control center is much more appropriate.

It also much better reflects the hierarchical structure of transport systems from a local level over a city municipal and regional level to a national level. Build it and protect it. But despite all these advantages, the development of such highly distributed, large scale and geographically dispersed systems raises two main challenges: firstly, how to build such a demanding system at all; secondly – but equally importantly – how to protect the now highly distributed and geographically dispersed systems with many nodes at different place.
