Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
On-board equipment (OBE) is an in-vehicle device that is able to contain one or more application
instances in order to support different intelligent transportation system (ITS) implementations such
as electronic fee collection (EFC). Examples of EFC applications are road toll collection/road charging,
localization augmentation (LAC) or compliance checking (CCC).
To assign the EFC application in the OBE to a certain user and/or vehicle, personalization should be
performed. This means that unique user and vehicle related data, needs to be transferred to the OBE.
The CEN/TR 16152 already assessed many aspects of the personalization process and it also defined
the overall personalization assets, i.e. application data, application keys and vehicle data.
Different communication media may be used for transferring the personalization assets to the OBE; but
for all media, common procedures may be applied such as an overall message exchange framework and
necessary security functionality in order to ensure data protection and integrity.
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, 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 parts define in
detail how the functions are realized on different defined communication media and interfaces.

Part 1:
Framework
1 Scope
This document describes:
— an overall description of the EFC personalization process;
— a description of EFC functionality that can be used for personalization.
The personalization process takes place within the domain of the entity that is responsible for the
application in the OBE.
The scope of the EFC functionality is limited to the interface between the personalization equipment
(PE) and OBE as shown in Figure 1. It is out of the scope of this document to define whether the
personalization functionality resides completely in the PE or whether this functionality instead resides
in a central system and where the PE is more or less “transparent”.

Scope of this document
Figure 1 — Scope of this document (box delimited by the dotted line)
It is outside the scope of this document to define the following:
— exact application command or message structures for the EFC personalization functionality (these
are dependent on the communication media and described in subsequent parts of the ISO/TS 21719
series);
— conformance procedures and test specification (this may be provided in a by separate set of
standards that are referred to in the subsequent parts of the ISO/TS 21719 series);
— setting-up of operating organizations (e.g. Toll Service Provider, personalization agent, trusted
third party, etc.);
— legal issues.
NOTE Some of the above issues are subject to separate standards prepared by CEN/TC 278, ISO/TC 204 or
ETSI ERM.
