vehicle-to-x communications

Vehicle-to-X (V2X) communication is a comprehensive term for the wireless exchange of information between a vehicle and any entity that may affect or be affected by it. This includes vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N). As a cornerstone technology for autonomous driving and Cooperative Intelligent Transport Systems (C-ITS), V2X enables real-time sharing of safety and traffic data. However, this connectivity creates a significant attack surface. Consequently, standards like ISO/SAE 21434 mandate a systematic Threat Analysis and Risk Assessment (TARA) for V2X systems. Furthermore, compliance with regulations such as UN R155 requires manufacturers to implement a robust Cybersecurity Management System (CSMS) to protect V2X communications throughout the vehicle lifecycle.

In enterprise risk management, applying V2X security involves a structured, three-step process. First, conduct a Threat Analysis and Risk Assessment (TARA) as defined in ISO/SAE 21434. This involves identifying V2X assets and analyzing potential threats like message spoofing or denial-of-service attacks. Second, implement security controls based on the TARA findings. A critical control is a Public Key Infrastructure (PKI) compliant with standards like IEEE 1609.2 to ensure message authenticity and integrity via digital signatures. Third, perform verification and validation through rigorous security testing, including penetration testing and fuzzing of V2X interfaces. Documenting this entire process is essential for demonstrating due diligence and achieving type approval under regulations like UN R155, a key metric for market access.

Taiwanese enterprises face three primary challenges with V2X implementation. First, standards fragmentation between DSRC and C-V2X technologies for different global markets increases R&D costs and complexity. The solution is to adopt flexible, software-defined hardware and focus development on target market standards. Second, the lack of a mature national Public Key Infrastructure (PKI) for V2X creates uncertainty for security credential management. To mitigate this, firms should engage in government pilot programs and partner with established global Security Credential Management System (SCMS) providers. Third, there is a significant talent gap in automotive cybersecurity. The priority action is to establish university partnerships and invest in robust internal upskilling programs to build a competent team, with an expected timeline of 1-2 years.
