As our cars become more and more complex, so do the computer systems that manage them and keep them under control. In the near future, communications from the embedded systems within cars to external networks will become more and more indispensable. This kind of communications, called "Car-to-X", have endless use cases: signalling system faults and incidents to a road operator, communicate between cars to manage the traffic, telling crossing cyclists that a vehicle is approaching and so on. Currently the most widespread standard for automotive embedded systems software, AUTOSAR, does not natively support a standardized way of achieving a fast and secure architecture for communicating with an external network.
