Vehicle-to-Infrastructure

Vehicle-to-Infrastructure (V2I) is a core component of Vehicle-to-Everything (V2X) communication technology, specifically enabling bidirectional wireless data exchange between vehicles and fixed Roadside Units (RSUs). Originating from Intelligent Transportation Systems (ITS) initiatives, V2I aims to enhance road safety and traffic efficiency. It allows vehicles to receive real-time data like traffic signal timing and hazard warnings, while transmitting their own data (e.g., speed, location) to traffic management centers. Within a risk management framework, securing V2I is critical, as malicious data could lead to unsafe vehicle actions. Therefore, compliance with standards like ISO/SAE 21434 for Threat Analysis and Risk Assessment (TARA) is mandatory. Furthermore, implementing security measures as defined in IEEE 1609.2, such as a Public Key Infrastructure (PKI) for message authentication and integrity, is essential to mitigate cyber threats, distinguishing it from closed in-vehicle networks.

In enterprise risk management, applying V2I security focuses on ensuring product compliance with cybersecurity regulations like UNECE R155 and mitigating liability risks. A three-step approach is common: 1) Conduct a Threat Analysis and Risk Assessment (TARA) based on ISO/SAE 21434 to identify threats like spoofed RSU messages or denial-of-service attacks and assess their safety impact. 2) Implement robust security controls, such as deploying a Public Key Infrastructure (PKI) compliant with IEEE 1609.2 for digital signatures on all V2I messages to ensure authenticity and integrity. 3) Establish a continuous monitoring and incident response mechanism, typically through a Vehicle Security Operations Center (VSOC), to detect anomalies in V2I communications. Leading automotive OEMs use this process to achieve high compliance rates, significantly reducing recall risks and potential liabilities from V2I vulnerabilities, thereby decreasing potential risk event occurrences by over 90% in simulated environments.

Taiwan enterprises face three primary challenges in V2I implementation. First, the lack of a unified communication standard, with both DSRC and C-V2X technologies being tested, creates uncertainty for product development. The solution is to develop dual-mode communication units or focus on single-standard applications in controlled environments like science parks while actively participating in national standard-setting bodies. Second, uneven deployment of roadside infrastructure limits service availability. Overcoming this requires public-private partnerships to prioritize RSU installation at high-risk intersections. Third, there is a shortage of cross-disciplinary talent skilled in both automotive engineering and cybersecurity. Enterprises should collaborate with universities on specialized training programs and engage expert consultants to build an initial V2I security validation team within a 6-month timeframe.
