V2X (Vehicle-to-Everything)

V2X (Vehicle-to-Everything) is a core technology of Intelligent Transportation Systems (ITS), enabling vehicles to wirelessly communicate with any entity that may affect them. It comprises V2V (Vehicle-to-Vehicle), V2I (Vehicle-to-Infrastructure), V2P (Vehicle-to-Pedestrian), and V2N (Vehicle-to-Network). In risk management, V2X introduces a significant attack surface. The ISO/SAE 21434 standard mandates a systematic Threat Analysis and Risk Assessment (TARA) for V2X systems to identify threats like message spoofing and implement controls. Unlike closed in-vehicle networks, V2X risks originate from untrusted external parties, necessitating robust security like a Public Key Infrastructure (PKI) for authentication and data integrity.

Securing V2X systems is critical for regulatory compliance and brand protection. A practical approach involves three steps: 1) Conduct a Threat Analysis and Risk Assessment (TARA) per ISO/SAE 21434, Clause 15, to identify threats like spoofed safety messages. 2) Implement security controls, such as deploying a Public Key Infrastructure (PKI) compliant with IEEE 1609.2 to ensure message authenticity and integrity using digital certificates. 3) Establish a continuous monitoring and response capability, typically through a Vehicle Security Operations Center (VSOC), as outlined in ISO/SAE 21434, Clause 10. Leading automotive OEMs implement these measures to comply with regulations like UN R155, achieving type approval and reducing cybersecurity incidents.

Taiwanese enterprises face three key challenges with V2X implementation. First, standards fragmentation (DSRC vs. C-V2X) increases development costs. The solution is to adopt modular architectures and actively participate in standards bodies like 3GPP and ETSI. Second, a shortage of interdisciplinary talent skilled in automotive, communications, and cybersecurity. This can be mitigated by partnering with expert firms like Winners Consulting for training based on ISO/SAE 21434. Third, the high cost of a trust infrastructure (PKI). A viable solution is to form an industry consortium or government-led initiative to create a shared Certificate Authority, reducing costs and ensuring interoperability. The priority action is to conduct a TARA to focus resources on the highest risks.
