ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

Introduction
Adjust space between Asian text and numbers
On-board equipment (OBE) isrefers to an in-vehicle device that can contain one or more application instances
to support different intelligent transportation system (ITS) implementations, such as electronic fee collection
(EFC). Examples of EFC applications are road toll collection (aka also known as "road user charging),"),
localization augmentation communication (LAC) and compliance check communication (CCC).
To assign the EFC application in the OBE to a certain user or vehicle, or both, personalization is performed.
This means that unique user and vehicle related data are transferred to the OBE. This document is applicable
to the EFC interface between the personalization equipment (PE) and OBE as shown in Figure 1Figure 1

CEN/TR 16152 already assesses many aspects of the personalization process and it also defines the overall
Formatted: Default Paragraph Font
personalization assets, i.e. application data, application keys and vehicle data.
Formatted: Default Paragraph Font
Different communication media may be used for transferring thethese personalization assets to the OBE;, but
Formatted: Default Paragraph Font
for all media, common procedures may be applied, such as an overall message exchange framework and
necessary security functionality to ensure data protection and integrity. Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers
By standardizing the personalization procedure, compatibility of personalization equipment is supported, and
the entity responsible for the personalization (e.g. a toll service provider) will be able to outsource parts of, or
a complete, personalization to a third party, e.g. another service provider or a personalization agent.
This document defines common functionality for personalization that is independent of the communication
media and personalization equipment (PE) used, while the subsequent. Subsequent parts of thisthe ISO 21719
Formatted: Font: 10 pt
series define in detail how the functions are realized on different defined communication media and interfaces.

The personalization process takes place within the domain of the entity that is responsible for the application

This document is applicable to the EFC interface, e.g. using dedicated short-range communication or
integrated circuit(s) card, between the personalization equipment (PE) and OBE as shown in Figure 1.
