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.
