Vehicle-to-Infrastructure (V2I)

Vehicle-to-Infrastructure (V2I) is a core component of V2X (Vehicle-to-Everything) technology, enabling bidirectional wireless data exchange between vehicles and fixed roadside infrastructure like traffic lights and sensors. Its primary goal is to enhance road safety and traffic efficiency. Within enterprise risk management, securing V2I communication is critical, as malicious data (e.g., a fake 'green light' signal) can directly cause severe accidents, posing significant operational and product liability risks. The ISO/SAE 21434 standard for automotive cybersecurity mandates a systematic Threat Analysis and Risk Assessment (TARA) for external interfaces like V2I. Unlike V2V (Vehicle-to-Vehicle), which is direct communication between cars, V2I relies on fixed infrastructure, and together they form the foundation of Cooperative Intelligent Transport Systems (C-ITS).

Applying V2I securely in enterprise risk management involves a structured process compliant with regulations like UNECE R155. Key steps include: 1. **Threat Analysis and Risk Assessment (TARA):** Based on ISO/SAE 21434, identify threats to the V2I link, such as spoofing or denial-of-service attacks, and assess their safety impact. 2. **Implement Security Controls:** Deploy countermeasures based on risk levels. A core control is using a Public Key Infrastructure (PKI) compliant with IEEE 1609.2 to digitally sign all messages, ensuring authenticity and integrity. 3. **Continuous Monitoring and Incident Response:** Establish a Vehicle Security Operations Center (VSOC) to detect anomalies in V2I traffic and deploy over-the-air (OTA) updates to patch vulnerabilities. This approach helps achieve 100% compliance and can reduce potential recall costs related to security flaws.

Taiwanese enterprises face three main challenges with V2I implementation: 1. **Standards Fragmentation:** The global split between DSRC and C-V2X communication standards increases R&D costs for exporters. The solution is to adopt Software-Defined Radio (SDR) platforms for hardware flexibility. 2. **Uneven Infrastructure Deployment:** V2I effectiveness depends on widespread Roadside Unit (RSU) coverage, which is currently limited to pilot zones in Taiwan. The strategy is to collaborate with public-private smart city projects to prioritize deployment in high-risk areas. 3. **Cybersecurity Talent Gap:** There is a shortage of experts with combined skills in automotive, wireless, and cybersecurity. Mitigation involves partnering with universities for talent development and engaging expert consultants to establish initial frameworks compliant with ISO/SAE 21434.
