Overview
ISO/TS 21719-2:2022 - Electronic fee collection - Personalization of on-board equipment (OBE) - Part 2: Using dedicated short-range communication defines a standardized application profile for personalizing in-vehicle tolling devices via DSRC (Dedicated Short‑Range Communication). Published as the second edition in 2022, the technical specification covers the DSRC personalization interface, the physical systems involved (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 to be used over the DSRC interface. Annexes include a PICS proforma (Annex B) and security computation examples (Annex E).
Key Topics
- Personalization interface (DSRC): Defines use of DSRC stacks and profiles for transferring personalization assets to OBEs.
- System and physical components: Requirements and roles for on-board equipment (OBE) and personalization equipment (PE) used during personalization.
- DSRC-link requirements: Layered DSRC considerations (physical through application) and supported DSRC stacks (CEN DSRC stack and others compliant with ISO 14906 / EN 12834).
- EFC personalization functions: Implementation of personalization functions from ISO/TS 21719-1 in the DSRC context (initialization, termination, read/write of identifiers and attributes).
- Security: Security data elements, mechanisms and examples for secure transfer and authentication over DSRC; references to cryptographic and MAC standards used for integrity and confidentiality. Annex A provides normative security calculations; Annex E gives worked examples.
- Conformance support: PICS proforma to document protocol information and aid interoperability testing (note: this document does not define conformance test procedures).
Applications and Practical Value
Who uses ISO/TS 21719-2:2022 and why:
- Toll service providers (TSPs) and personalization agents - for secure, interoperable personalization of OBEs at production, distribution or in-field locations.
- OBE and PE manufacturers / system integrators - to implement DSRC-based personalization functions consistent with ITS and EFC application interfaces.
- Transport authorities and operators - to ensure compatibility of OBE personalization across suppliers and jurisdictions.
- Test labs and consultants - to prepare PICS declarations and validate DSRC personalization implementations (note: specific conformance/test specs are out of scope and may be in other standards).
Practical benefits include consistent personalization workflows, improved interoperability of DSRC-based tolling equipment, and standardized security mechanisms for protecting user and vehicle data during personalization.
