The purpose of this project is to raise the issue of cybersecurity for autonomous vehicles to a system level. The focus is on enabling a positive societal development. In this pre-study we will use a new mobility arena named ELIN, which launched in Linköping 2020 involving eight public and private stakeholder organisations. At a technical level, ELIN combines an autonomous bus with a digital infrastructure. In particular it will include investigating a Control Tower functionality, which enables external control of the bus from a command centre. This creates new possibilities as well as new risks, in particular relating to cyber threats. We aim to investigate and analyse these risks, but also study related areas and fields to find standards and initiatives and how stakeholders in other domains are dealing with similar problems. The project will organise three workshops to gather relevant stakeholders as well as practically study the ELIN platform from a security perspective.
