Intelligent transport systems — ITS station security services for secure session establishment and authentication between trusted devices

Standard Details

This document contains specifications for a set of ITS station security services required to ensure the authenticity of the source and integrity of information exchanged between trusted entities, i.e.:

     between devices operated as bounded secured managed entities, i.e. ""ITS Station Communication Units"" (ITS-SCU) and ""ITS station units"" (ITS-SU) as specified in ISO 21217; and

     between ITS-SUs (composed of one or several ITS-SCUs) and external trusted entities such as sensor and control networks.

These services include the authentication and secure session establishment which are required to exchange information in a trusted and secure manner.

These services are essential for many 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.
