ABSTRACT: Vehicles are increasingly connected with their environment, resulting in numerous improvements
for the driver like semi-autonomous or fully autonomous driving to avoid severe road accidents.
Additional environment information helps to improve driving behaviour and to reduce fuel consumption.
The permanent wireless access to the vehicles moreover opens up new business models, e.g.
the remote software update to eliminate costly recalls, but also online services or the comfortable toll
control. On the other hand any external access to the vehicle increases the risk of manipulations and
cybercrime. Modern semiconductor solutions enable security systems that protect both personal data
and life and limb of the road users.
In the future car-to-car (C2C) and car-to-infrastructure (C2I) communication will lead to an improvement
of safety and efficiency in road traffic. For instance drivers can be warned of roadway damages or accidents
on their routes. Remote diagnostics over the air interface could indicate necessary service measures
at an early stage. However there is sensible information exchanged like position and speed. The
integrity of these data must be protected. Up to now it is unsettled, to whom these data belong and if they
are personal data which, as data protection law stands, face considerably more stringent regulations.
KEY WORDS: Connected car, C2C, C2I, remote diagnostics
