Abstract

Current automotive systems contain security solutions provided as singular solutions. Security mechanisms are implemented for each automotive function individually. This individual security design leads to several problems: combining several functions that are for its own secure may not result in a secure system. Furthermore, the combination of functions might also lead to situations, where mechanisms erroneously detect a security threat. This paper argues that new features, such as Car-2-Car communication or autonomous driving, will result in new information and communication technology (ICT) architectures of cars. The paper will outline basic properties of this architecture and summarize resulting security threads. We will argue that security needs to be treated in a holistic way and that the design must be suitable for adaptive, multiple independent levels of security (MILS) architecture.
