Currently, for V2X direct communication, there is no available common policy (certificate policy for Public Key Infrastructure, or PKI, operators) for Security Credential Management System (SCMS) in the U.S. or Canada. A few SCMS providers created their own policies, which are not only incomplete but there are no published common policy documents feasible for SCMS PKI operation, hindering the widespread adoption of the technology. The Government of Canada sponsored an effort which resulted in a model for consideration.

A common Certificate Policy (CP) would help facilitate an ecosystem supporting interoperability and shared trust for V2X direct communication. The European Union addresses this issue by taking a central regulatory role, creating the CP, Security Policy (SP) and C-ITS Point of Contact (CPOC) documents that govern a V2X PKI for direct communication. North America need not duplicate what has been done elsewhere, though an accepted policy will build a greater ecosystem and support V2X direct deployment among a diverse set of automakers and other transport agencies.

The Certificate Policy Proposal contributing to this Work Item (WI) evolved into a Technical Report (TR) that develops a clear CP leveraging global best practices for security PKI and practical experience securing V2X direct communication, as well as common processes to facilitate an approach to SCMS.

For V2X mobile network communication, certificates are needed to authenticate interconnected backend systems and to protect communication between the systems. This Technical Report also elaborates on how to handle those certificates.

Cellular Vehicle-to-Everything, or C-V2X, is an umbrella term that encompasses all 3GPP V2X technologies, including both direct (PC5) and mobile network communications (Uu). In many cases, both direct and network modes of C-V2X can be used for the same or similar automotive and Intelligent Transport System (ITS) applications, yet with different service characteristics. However, there are fundamental differences when it comes to the architecture and realisation of different Use Cases applying mobile network vs. direct, short-range, communications. This leads to different ways of handling security, privacy, and how to ensure data quality – the fundamental requirements of every ITS service – when using C-V2X mobile network communication or direct communication. This is already reflected in other organisations such as ITS America.

This 5GAA paper provides an overview of how security, privacy, and data quality are addressed for C-V2X using mobile network and backend communications, also known as Vehicle-to-Network-to-Everything (V2N2X) solutions.

The paper was originally published in December 2024. The current downloadable version is the updated edition, released on 3 June 2025. 5GAA remains committed to keeping all its publications accurate and up to date.

The societal ambitions of zero fatalities and climate neutrality in road transportation, as well as future ambitions of automated driving require a new approach to the handling of road traffic information. The key stakeholders of the ecosystem, global automotive OEMs, service providers (SPs) and infrastructure owner-operators (IOOs), need new digital methods of operating and interworking.

This white paper proposes a transformative approach for automotive stakeholders, emphasizing scalable digital data exchange and a federated architecture to manage road traffic information efficiently. The architecture ensures bidirectional communication, delivering static, semi-static, and near real-time data for safe and efficient transportation. The paper concludes with recommendations for a National Roadway Digital Strategy, federated information-sharing structures, and aligned investments. Emphasising the integration of technologies and data-driven decision-making, it aligns with 5GAA’s mission to propel road traffic operations into the digital age.
