Connected mobility is developing at a rapid pace. The focus here is on functional and traffic safety together with intelligent technologies. Both are only possible through V2X communication: the exchange of data between vehicles and with the traffic infrastructure.

V2X constantly provides networked vehicles with a large amount of information to guide them, automated or not, to make decisions that are appropriate for traffic. The cybersecurity of V2X communications is of key importance. This is because the effectiveness of the system depends on how accurate and trustworthy the information is. Traditionally, in IT security, the trustworthiness of information is ensured by identifying and authenticating its sender.

To ensure data security and privacy, V2X communications require a public key infrastructure (PKI) - the Security Credential Management System (SCMS) for North America (NA) and the Cooperative Intelligent Transportation System Credential Management System (CCMS) for Europe (EU). These PKI systems issue pseudonymous certificates that allow communicating systems to identify only authorized senders as trusted. SCMS and C-ITS CMS have long been used in numerous V2X pilot projects and are also envisioned for future national V2X infrastructures and beyond.

The ESCRYPT CycurV2X-PKI platform is a robust, modular and scalable standards-compliant credential management system that registers and manages complete vehicle and transportation infrastructure security services. In doing so, ESCRYPT CycurV2X-PKI implements the security services for both the North American and European V2X standards.
