V2X Security & Privacy: The Current State and its Future

Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is currently a focus of research and standardization in the USA, Europe and Asia. It is believed that V2V safety applications are able to reduce traffic fatalities significantly. Data security was identified as a major technical aspect to resolve before potential deployment. In particular, communication security and privacy are main aspects to consider but also physical security of the microcontroller, key injection, privacy mechanisms implemented by government agencies, and policy questions around security. This article provides an overview of the current state and of open issues.
