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.

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 www .iso .org/

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 first edition cancels and replaces ISO/TS 19299:2015, which has been technically revised.
The main changes compared to the previous edition are as follows:
— added requirements and security measures for the use of common payment media according to
ISO/TS 21193;
— updated data protection considerations in Annex G, in order to take into account the European
Union’s new General Data Protection Regulation (i.e. Directive 2016/679/EC).

Introduction
Context of this document
The development process for a security concept and implementation to protect any existing electronic
fee collection (EFC) system normally includes several steps as follows (see Figure 1):
— definition of the security objectives and policy statements in a security policy;
— threat analysis with risk assessment to define the security requirements;
— development of the security measures followed by the development of security test specifications.
Figure 1 — Development path for the security documents
Each actor in an existing EFC system implements the defined security measures and supervises their
effectiveness. When a security measure is found not working properly, an improvement process is
started. The development of the EFC security framework follows this approach, with the following
limitations:
— No standard security policy exists, nor can it be defined: The security policy can only be defined by
the responsible stakeholders and it is limited by laws and regulations. Nonetheless, this document
provides basic examples of possible security policies (in Annex E to Annex F).
— No standard risk assessment is possible: Risk assessment compares possible losses to stakeholders
with the required resources (e.g. equipment, knowledge, time) to perform an attack. In a real system,
risk assessment is based on the evaluation of the costs and benefits of each countermeasure.
— No specific system design or configuration was deemed as universally applicable. Only the available
EFC base standards were taken as references. Specific technical details of a particular system
(e.g. servers, computer centres, and de-centralised elements like roadside equipment) need to be
additionally taken into consideration when implementing security measures.

Selection of requirements and respective security measures for an existing EFC system is based on the
security policy and the risk assessment of several stakeholders’ systems. Due to the fact that there is
no overall valid security policy, nor is there the possibility to provide a useful risk assessment, the EFC
security framework provides an extensive (but non-exhaustive) toolbox of requirements and security
measures.
To understand the content of this document, the reader should be aware of the methodological
assumptions used to develop it. Security of an (interoperable) EFC scheme depends on the correct
implementation and operation of a number of processes, systems, and interfaces. Only a reliable end-to-
end security ensures the accurate and trustworthy operation of interacting components of toll charging
environments. Therefore, this security framework also covers systems or interfaces which are not EFC
specific, like back office connections. An application independent security framework for such system
parts and interfaces, an information security management system (ISMS), can be found, for example, in
the ISO/IEC 27000 series.
The development process of this document is described briefly in the steps below:
a) Definition of the stakeholder objectives and generic requirements as the basic motivation for the
security requirements (Annex C). A possible security policy with a set of policy statements is
provided in Annex E, and an example of a European electronic toll service (EETS) security policy is
given in Annex F.
b) Based on the EFC role model and further definitions from the EFC architecture standard
(ISO 17573-1), the specification defines an abstract EFC system model as the basis for a threat
analysis, definition of requirements, and security measures.
c) The threats on the EFC system model and its assets are analysed by two different methods: an
attack-based analysis and an asset-based analysis. The first approach considers several threat
scenarios from the perspective of various attackers. The second approach looks in depth on threats
against the various identified assets (tangible and intangible). This approach, although producing
some redundancy, ensures completeness and coverage of a broad range of risks (see Annex D).
d) The requirements specification (see Clause 6) is based on the threats identified in Annex D.
Each requirement is at least motivated by one threat and each threat is covered by at least one
requirement.
e) The definition of security measures (see Clause 7) provides a high-level description of recommended
possible methods to cover the developed requirements.
f) The security specifications for interoperable interface implementation (Clause 8) provide detailed
definitions, such as for message authenticators. These specifications represent an add-on for
security to the corresponding relevant interface standards.
g) Basic key management requirements that support the implementation of the interoperable
interfaces are described in Clause 9. The toll charging environment uses cryptographic elements
(e.g. keys, certificates, certificate revocation lists) to support security services like confidentiality,
integrity, authenticity, and non-repudiation. This section of the document covers the (initial) setup
of key exchange between stakeholders and several operational procedures, such as key renewal,
certificate revocation.
h) A general trust model (see Clause 5) is defined to form the basis for the implementation of
cryptographic procedures to ensure confidentiality, integrity, and authenticity of exchanged
data. In this context, the security framework references approved international standards for the
implementation of cryptographic procedures enhanced by EFC specific details where needed.
A stakeholder of an EFC scheme who wants to use this security framework should to do the following:
— define a security policy for the EFC scheme (may involve more than one stakeholder in an interoperable
EFC scheme). Some examples for a security policy and its elements are provided (in Annex E and
Annex F) as an aid to build up a secure system for a concrete interoperability framework (including
the European electronic toll service).

— identify the relevant processes, systems and interfaces, and match them to the EFC security
framework;
— select the corresponding security requirements according to the security policy;
— implement the security measures associated to the selected requirements;
— provide evidence of compliance of its systems, processes, and interfaces with the requirements
of this document. Evidence can be provided by a self-declaration, an internal or external audit, or
other certifications.
