Infrastructure-to-Vehicle (I2V)

Infrastructure-to-Vehicle (I2V) is a key technology within the Vehicle-to-Everything (V2X) ecosystem, enabling wireless data exchange between roadside infrastructure and vehicles. It provides vehicles with non-line-of-sight information, such as traffic signal timing, hazard warnings, and road conditions, to enhance safety and traffic efficiency. From a risk management perspective, securing I2V communication is critical, as malicious actors could spoof signals to cause accidents. The **ISO/SAE 21434** standard for automotive cybersecurity engineering mandates a Threat Analysis and Risk Assessment (TARA) for such external interfaces. Unlike V2V (Vehicle-to-Vehicle) communication, I2V relies on fixed, authoritative infrastructure, providing a broader and more reliable data source for Cooperative Intelligent Transport Systems (C-ITS).

Applying I2V in enterprise risk management involves securing its communication channels to ensure safety and compliance. Key steps include: 1) **Threat Analysis and Risk Assessment (TARA):** Following **ISO/SAE 21434**, identify threats like signal spoofing or denial-of-service attacks and assess their safety impact. 2) **Implement Security Controls:** Deploy a Public Key Infrastructure (PKI) compliant with **IEEE 1609.2** to digitally sign and authenticate all I2V messages, ensuring data integrity and origin verification. 3) **Continuous Monitoring and Response:** Establish a Vehicle Security Operations Center (VSOC) to monitor I2V traffic for anomalies and develop an incident response plan as required by **UN Regulation No. 155**. This framework allows for rapid detection and mitigation, including deploying over-the-air (OTA) security patches. Major automakers use this approach to achieve regulatory compliance and reduce false information risks by over 99%.

Taiwan enterprises face several key challenges with I2V implementation. First, **infrastructure fragmentation**, with competing standards like DSRC and C-V2X coexisting, creates interoperability risks and increases development costs. A solution is to adopt dual-mode communication modules and advocate for a unified national standard. Second, a **lack of localized threat intelligence** means that generic risk models may not address Taiwan-specific traffic scenarios or geopolitical risks. Establishing a local Automotive Information Sharing and Analysis Center (Auto-ISAC) would help create more accurate TARA models. Third, **high compliance and validation costs** for standards like ISO/SAE 21434 can be a barrier for smaller suppliers. Leveraging cloud-based security testing platforms and forming industry alliances to share validation costs can mitigate this challenge.
