EN ISO 21719-1:2026 PDF

Overview

EN ISO 21719-1:2026 sets a foundational framework for the personalization of on-board equipment (OBE) used in electronic fee collection (EFC) systems. Developed by CEN and aligned with ISO 21719-1:2026, this standard defines the essential functions and security procedures required when configuring OBE with user or vehicle-specific data. The document focuses on the personalization interface between the personalization equipment (PE) and the OBE, supporting interoperability and secure asset transfer across various EFC applications, such as road tolling and compliance verification.

The standard does not specify technical communication details, test procedures, or operational models for involved organizations, deferring such specifics to later parts of the ISO 21719 series or companion standards.

Key Topics

• Personalization Process: The standard outlines the process for customizing OBE with necessary data, including payment information, vehicle identification, application keys, and security credentials.

• Scope of Personalization: Personalization occurs within the domain of the entity responsible for the OBE application (e.g., toll service provider). The process involves securely writing specific data into the OBE, ensuring its readiness for use within defined tolling or EFC environments.

• Core Functions and Security: The standard introduces a set of basic EFC personalization functions, with security features to prevent unauthorized access and ensure data integrity:

  • Write functionality for recording personalization assets
  • Access control to validate the origin of personalization commands
  • Application data encryption during transfer
  • Authenticators for both requests and responses to verify data integrity

• Interface Requirements: The focus is on the technical interface between PE and OBE. Communication may occur via dedicated short-range communications or integrated circuit cards, supporting flexibility across different EFC deployment scenarios.

Applications

EN ISO 21719-1:2026 applies to a variety of intelligent transport system (ITS) and electronic tolling scenarios, where secure and efficient OBE personalization is essential. Its use cases include:

• Road Tolling Systems: Ensures each vehicle's OBE is uniquely programmed for proper toll recognition and billing.

• Multi-application OBEs: Supports OBEs that handle several ITS functions, including compliance checking and localization, by managing multiple application instances and assets.

• Outsourced Personalization: The standardized framework makes it possible for toll service providers to outsource OBE personalization to third parties, enhancing operational flexibility.

• Security-critical Environments: By emphasizing secure data transfer and access controls, the standard is suitable for environments where data integrity and privacy are paramount.

Related Standards

Adopting EN ISO 21719-1:2026 is facilitated by referencing and aligning with several important standards:

• ISO 14906: Electronic fee collection-Application interface
• EN 15509: EFC-Interoperability application profile for DSRC
• ISO 12813 / ISO 13141: OBE requirements for EFC using different communication media
• ISO 17573-2: EFC system architecture and vocabulary
• CEN/TR 16152: Guidance on the OBE personalization process
• Other parts of the ISO 21719 series: Detailing communication media and implementation specifics

Organizations implementing EFC or managing OBEs benefit from the interoperability, security, and clarity brought by EN ISO 21719-1:2026-enabling streamlined, reliable, and future-proof deployment of electronic tolling and road usage charging systems.
