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:
devices operated as bounded secured managed entities, i.e. ITS Station Communication Units (ITS-SCU) and ITS station units (ITS-SU) 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 authentication and secure session establishment which are required to exchange information in a trusted and secure manner.
These services are essential for many ITS applications and services including time-critical safety applications, automated driving, remote management of ITS stations (ISO 24102-2[5]), and roadside/infrastructure related services.
