Interview: Three questions for Joachim Klink, Head of Autonomous Driving & Smart Mobility at T-Systems International
Mr. Klink, T-Systems has been supporting DEKRA in developing a concept for testing vehicles of future generations since the beginning of 2020. Why do we need to rethink the previous model?
Software in vehicles is increasingly being brought into focus when it comes to the evaluation of driving safety. In addition, vehicle software is changing with increasing frequency – even when vehicles have long been in the field. Tesla, for example, rolled out more than 150 vehicle software updates in 2020, about 30 percent of which have a potential impact on driving safety, according to our analysis.
What do you think of the design and tasks of a trust center?
Among other things, it’s intended to give testing organizations non-discriminatory access to data relevant to driving safety and the environment. Of course, it wouldn’t be practical to carry out a new type approval test after every software update. On the other hand, every software change involves risks because software is never error-free. It would be very beneficial to safety if an independent third party such as DEKRA were granted direct access to the code for random or occasion-based checks.
What requirements must the intended trust center meet in terms of data security?
We need to ensure that only authorized organizations have access to it. Another issue is the definition of roles and rights – in other words, when and how does who get access to which data. A rather theoretical danger is the manipulation of vehicle data. This doesn’t play a role for the trust center, however, as we take a “read-only” approach.
