Vehicle-to-Everything communications are technologies that enable message exchange between vehicles and other vehicles or infrastructure components. These technologies are employed for the Intelligent Transportation Systems which enable the implementation of safety-related applications such as electronic emergency braking light, cooperative collision avoidance or traffic light announcements. The messages exchanged between vehicles and other vehicles or infrastructure elements, called Basic Safety Messages, contain sensitive information such as time, position, and motion data. It is critical to protect this information to prevent users tracking and attacks that could harm users' safety. To address the security issues, Crash Avoidance Metrics Partners LLC developed the Security Credential Management System to support the establishment of a Public Key Infrastructure for V2X security, which issues certificates to system participants.
