V2N2X security, privacy, and data quality

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.
