ITU-T X.1379 PDF

Roadside unit (RSU) is a critical node in an intelligent transportation system (ITS) that enables vehicle-to-infrastructure (V2I) communication between on-board devices on vehicles and roadside infrastructures. RSU interacts with nearby vehicles, traffic control systems and a vehicle-toeverything (V2X) cloud service centre through various wired/wireless connections.

This Recommendation describes a function model and deployment issues of RSU for security analysis of RSU. It then identifies potential security threats to RSU before specifying the security requirements of the RSU to counter measure the security threats that are identified.
