V2X Communications

Vehicle-to-Everything (V2X) communications is a wireless technology enabling vehicles to exchange real-time information with any relevant entity in their environment. This includes Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), and Vehicle-to-Network (V2N). In enterprise risk management, V2X is a primary attack surface due to its open nature. The automotive cybersecurity standard, ISO/SAE 21434, mandates a Threat Analysis and Risk Assessment (TARA) for V2X systems to mitigate risks like message spoofing and DoS attacks. Unlike traditional telematics, which is often non-safety-critical, V2X's low-latency, high-reliability communication directly impacts vehicle safety, demanding a much higher level of security.

Enterprises apply V2X risk management by integrating cybersecurity into the vehicle lifecycle, a requirement for UN R155 compliance. Key steps include: 1) Performing a TARA based on ISO/SAE 21434 to identify threats to V2X interfaces, such as spoofed safety messages. 2) Implementing a secure architecture using a Public Key Infrastructure (PKI) compliant with standards like IEEE 1609.2 to ensure message authenticity and integrity, often secured by Hardware Security Modules (HSMs). 3) Establishing continuous monitoring via a Vehicle Security Operations Center (VSOC) with an Intrusion Detection System (IDS) to detect anomalies. This approach helps reduce security incidents by over 90% and ensures regulatory compliance.

Taiwanese enterprises face three main challenges. First, regulatory fragmentation between global V2X standards (DSRC vs. C-V2X) creates R&D and export uncertainty. Second, the high cost of deploying roadside infrastructure for V2I applications is a significant barrier for small and medium-sized enterprises. Third, there is a shortage of talent with specialized skills in automotive cybersecurity. To overcome these, companies should adopt flexible hardware designs (e.g., SDR), collaborate on government-led pilot projects to share infrastructure costs, and partner with expert consulting firms to bridge the talent gap and establish ISO/SAE 21434-compliant processes. Prioritizing V2V and V2N applications can also reduce initial investment.
