ISO 21177:2024 outlines the specifications for a set of ITS station security services designed to ensure the authenticity and integrity of information exchanged between trusted entities, specifically:
- between devices that operate as bounded secured managed entities, namely “ITS Station Communication Units” (ITS-SCU) and “ITS station units” (ITS-SU), as defined in ISO 21217; and
- between ITS-SUs (comprising one or more ITS-SCUs) and external trusted entities such as sensor and control networks.
These services encompass authentication and secure session establishment, essential for exchanging information in a trustworthy and secure manner.
These services are crucial for numerous intelligent transport system (ITS) applications and services, including time-critical safety applications, automated driving, remote management of ITS stations (ISO 24102-2), and roadside/infrastructure-related services.
