With the advent of onboard HPC, how will auto cyber security develop?

With vehicle architectures transforming and software increasingly defining the car, onboard HPC could become commonplace. What are the security implications? By Xavier Boucherat

Compared with models some 20 years ago, the number of lines of code in the average car has jumped by orders of magnitude.
