Vehicle-to-everything

Vehicle-to-everything (V2X) is a wireless communication framework that enables vehicles to exchange real-time information with their surroundings, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N) communications. In risk management, V2X is a primary attack surface. The ISO/SAE 21434 standard, "Road vehicles — Cybersecurity engineering," mandates a systematic Threat Analysis and Risk Assessment (TARA) for external interfaces like V2X. This approach focuses on protecting against malicious external attacks, ensuring the confidentiality, integrity, and availability of V2X data, which distinguishes it from the functional safety focus of ISO 26262.

Enterprises apply V2X risk management by integrating cybersecurity into the product lifecycle, complying with ISO/SAE 21434 and UN R155. The process involves three key steps: 1. Conduct a Threat Analysis and Risk Assessment (TARA) to identify threats like message spoofing or Denial-of-Service (DoS) attacks and evaluate their safety impact. 2. Implement cybersecurity controls based on risk levels, such as a Public Key Infrastructure (PKI) for message authentication, data encryption, and an Intrusion Detection and Prevention System (IDPS). 3. Establish a Vehicle Security Operations Center (VSOC) for continuous monitoring and incident response. A leading OEM implemented this, reducing potential risk events from communication vulnerabilities by over 80% and achieving a 100% audit pass rate for vehicle type approval.

Taiwanese enterprises face three main challenges with V2X implementation. First, fragmented international standards (DSRC vs. C-V2X) create development and export complexities. Second, inconsistent cybersecurity capabilities across the supply chain make it difficult for smaller suppliers to meet the stringent requirements of ISO/SAE 21434 demanded by OEMs. Third, a lack of large-scale, integrated testbeds hinders the validation of V2X security and interoperability in real-world scenarios. To overcome these, firms should track global standards, adopt flexible designs, implement a robust supplier cybersecurity management program, and leverage government-supported testbeds for validation. A proactive approach can establish a foundational framework within 6-12 months.
