Vehicle to Everything (V2X)

Vehicle to Everything (V2X) is a wireless communication technology that allows vehicles to exchange real-time information with their surroundings, including other vehicles (V2V), infrastructure (V2I), pedestrians (V2P), and networks (V2N). As a cornerstone for Cooperative Intelligent Transport Systems (C-ITS) and advanced autonomous driving, V2X enhances safety by sharing data like position and speed. However, these external interfaces are prime targets for cyberattacks. Consequently, regulations like UN R155 mandate a certified Cybersecurity Management System (CSMS) covering V2X systems. The ISO/SAE 21434 standard further requires a Threat Analysis and Risk Assessment (TARA) for V2X components throughout the vehicle lifecycle to mitigate potential cybersecurity risks.

In enterprise risk management, V2X application focuses on securing communications and ensuring compliance. Key steps include: 1) Asset Identification and Threat Modeling: Define V2X components (e.g., On-Board Units) as critical assets per ISO/SAE 21434 and model threats like spoofing and tampering using frameworks like STRIDE. 2) Risk Assessment and Control Implementation: Conduct a TARA to quantify risks, such as spoofed V2I traffic signals. Implement controls like a Public Key Infrastructure (PKI) based on the IEEE 1609.2 standard for message authentication. 3) Continuous Monitoring and Incident Response: Establish a Vehicle Security Operations Center (VSOC) to monitor V2X traffic for anomalies, fulfilling the post-production requirements of UN R155. These steps help achieve a high audit pass rate and reduce risk event probability significantly.

Taiwanese enterprises face three main challenges with V2X security. First, regulatory fragmentation, as they must comply with varying standards (e.g., DSRC in the US vs. C-V2X in China) for different export markets. Second, complex supply chain security, where ensuring Tier-1 and Tier-2 suppliers are compliant with ISO/SAE 21434 is difficult. Third, a shortage of talent with hybrid expertise in automotive engineering, communications, and cybersecurity. To overcome these, companies should adopt a flexible, modular security architecture, enforce stringent supplier cybersecurity requirements via contractual agreements, and collaborate with research institutions like ITRI for talent development and access to advanced testing facilities. Prioritizing a robust supplier management program is a critical first step.
