Overview
CEN ISO/TS 21719-2:2022 - Electronic fee collection (EFC) - Personalization of on-board equipment (OBE) - Part 2: Using dedicated short-range communication (DSRC) defines a standardized application profile for transferring and storing personalization data to in‑vehicle tolling devices over a DSRC interface. Published in 2022 and harmonized by CEN/ISO, this Technical Specification covers the personalization interface (DSRC), the physical systems (OBE and personalization equipment - PE), DSRC‑link requirements, EFC personalization functions (as referenced in ISO/TS 21719-1), and the security data elements and mechanisms required for secure personalization.
Key topics and requirements
- Personalization interface: Defines how DSRC is used as the interface between PE and OBE for secure transfer of user-, vehicle- and application‑specific data.
- System components: Requirements for On‑Board Equipment (OBE) and Personalization Equipment (PE), including supported DSRC stacks and interaction flows.
- DSRC‑link requirements: Lower‑layer DSRC stack compatibility, with an application profile built on the CEN DSRC stack and references to EN 13372, ISO 14906 and EN 12834 for stack interoperability.
- EFC personalization functions: Mapping of personalization services from ISO/TS 21719‑1 to the DSRC interface (initialization, retrieval of OBE identifier, writing application data, transaction handling).
- Security: Definition of security data elements, mechanisms and procedures to protect confidentiality, integrity and authenticity during personalization. Annex A provides security calculations; Annex E contains security computation examples.
- Conformance & testing aids: A Protocol Information Conformance Statement (PICS) proforma is provided in Annex B to assist implementers in declaring supported features. Note: the document does not define conformance test procedures or legal/organizational setups.
Applications and who uses it
This specification is essential for:
- Toll Service Providers (TSPs) planning secure personalization workflows or outsourcing personalization to agents.
- OBE manufacturers implementing DSRC personalization interfaces and EFC applications.
- Personalization agents and integrators building or operating Personalization Equipment (PE).
- ITS system architects, test labs and certification bodies using the PICS proforma and security examples during integration and evaluation.
Use cases include secure onboarding of account credentials, vehicle identifiers and cryptographic keys into tolling OBEs via short‑range communication at distribution centers or service points.
