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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems, in
collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC
278, Intelligent transport systems, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO/TS 21719-2:2018), which has been
technically revised.
The main changes are as follows:
— addition of subclause 5.4 on the Conformance statement;
— minor updating of terms, including a reference to ISO/TS 17573-2 as the primary source.
A list of all parts in the ISO 21719 series can be found on the ISO website.

Introduction
On-board equipment (OBE) is an in-vehicle device that contains one or more application instances to
support different intelligent transport system (ITS) implementations such as electronic fee collection
(EFC).
To assign the EFC application in the OBE to a certain user or/and vehicle, personalization is performed.
This means that unique user- and vehicle-related data needs to be transferred and stored in the OBE.
CEN/TR 16152 assessed many aspects of the personalization process and defined the overall
personalization assets: application data, application keys and vehicle data.
Different communication media may be used for transferring the personalization assets to the OBE. An
overall message exchange framework and required security functionality may be applied for all media
common procedures, 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 (TSP)] will
further be able to outsource partial or complete personalization to a third party or to another service
provider or personalization agent.
The scope of the personalization functionality is illustrated in Figure 1 and is limited to the dedicated
short-range communication (DSRC) interface between the personalization equipment (PE) and the OBE.
Figure 1 — Scope for this document (box delimited by a dotted line)
This document defines a complete application profile using the personalization functionality described
in ISO/TS 21719-1, on top of a CEN DSRC stack according to the DSRC communication profiles as
specified in EN 13372 and using the EFC Application Interface according to ISO 14906.
This document further defines in the annexes the use of this application profile on top of other DSRC
communication stacks that are compliant with the application layer interfaces as defined in ISO 14906
and EN 12834.
Figure 2 shows the scope of this document from a DSRC-stack perspective.
