Electronic fee collection - Application interface definition for dedicated short-range communication (ISO 14906:2018)

The EFC application interface is the EFC application process interface to the DSRC application layer, as
can be seen in Figure 1 below. This document comprises specifications of:
— EFC attributes (i.e. EFC application information) that can also be used for other applications and/or
interfaces,
— the addressing procedures of EFC attributes and (hardware) components (e.g. ICC and MMI),
— EFC application functions, i.e. further qualification of actions by definitions of the concerned services,
assignment of associated ActionType values and content and meaning of action parameters,
— the EFC transaction model, which defines the common elements and steps of any EFC transaction,
— the behaviour of the interface so as to ensure interoperability on an EFC-DSRC application
interface level.
This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (see ISO/
IEC 7498-1), and it is as such not primarily concerned with the implementation choices to be realised at
either side of the interface.
This document provides security-specific functionality as place holders (data and functions) to enable
the implementation of secure EFC transactions. Yet the specification of the security policy (including
specific security algorithms and key management) remains at the discretion and under the control of
the EFC operator, and hence is outside the scope of this document.

Le présent document spécifie l'interface d'application dans le contexte des installations de perception du télépéage (EFC) utilisant des communications dédiées à courte portée (DSRC).

Elektronsko pobiranje pristojbin - Definicija aplikacijskega vmesnika za posebne komunikacije kratkega dosega (ISO 14906:2018)

Aplikacijski vmesnik za elektronsko pobiranje pristojbin (EFC) je aplikacijski postopkovni vmesnik za elektronsko pobiranje pristojbin za aplikacijsko plast DSRC, kot
je razvidno na sliki 1 spodaj. Ta dokument zajema specifikacije za:
– atribute elektronskega pobiranja pristojbin (tj. informacije sistema elektronskega pobiranja cestnin), ki jih je mogoče uporabiti tudi za druge aplikacije, in/ali
vmesnike,
– obravnavane postopke atributov sistema elektronskega pobiranja cestnin in sestavnih delov (strojne opreme) (npr. kartice z integriranim vezjem (ICC) in vmesniki človek-stroj (MMI)),
– funkcije sistema elektronskega pobiranja pristojbin, tj. nadaljnja kvalifikacija dejanj z definicijami obravnavanih storitev,
dodelitev povezanih vrednosti »ActionType« ter vsebina in pomen parametrov dejanj,
– model transakcije elektronskega pobiranja pristojbin, ki določa skupne elemente in korake katere koli transakcije elektronskega pobiranja pristojbin,
– delovanje vmesnika za zagotavljanje interoperabilnosti na ravni aplikacijskega vmesnika
za EFC-DSRC.
To je vmesniški standard, ki se ravna po načelu povezanih odprtih sistemov (OSI) (glej ISO/
IEC 7498-1) in kot tak ni primarno povezan z načini izvajanja, ki jih je treba udejanjiti na
obeh straneh vmesnika.
Ta dokument zagotavlja varnostno specifično funkcijo označbe mesta (podatki in funkcije), kar omogoča
izvajanje varnih transakcij elektronskega pobiranja pristojbin. Vendar pa specifikacija varnostne politike (vključno
s posebnimi varnostnimi algoritmi in upravljanjem ključev) ostaja v presoji in pod nadzorom
upravljavca elektronskega pobiranja pristojbin in zato ne spada na področje uporabe tega dokumenta.

Introduction

This document specifies an application interface for electronic fee collection (EFC) systems, which

is based on dedicated short-range communication (DSRC). It supports interoperability between

EFC systems on an EFC-DSRC application interface level. This document is intended for DSRC

charging applications, but specifically the definition of EFC data elements is valid beyond the use of

a DSRC charging interface and might be used for other DSRC applications (e.g. compliance checking

communication) and/or on other interfaces (e.g. the application interface of autonomous systems).

This document provides specifications for the EFC transaction model, EFC data elements (referred to

as attributes) and functions, from which an EFC transaction can be built. The EFC transaction model

provides a mechanism that allows handling of different versions of EFC transactions and associated

contracts. A certain EFC transaction supports a certain set of EFC attributes and EFC functions as

defined in this document. It is not envisaged that the complete set of EFC attributes and functions be

present in each piece of EFC equipment, on-board equipment (OBE) or roadside equipment (RSE).

This document provides the basis for agreements between operators, which are needed to achieve

interoperability. Based on the tools specified in this document, interoperability can be reached by

operators recognising each others' EFC transactions (including the exchange of security algorithms and

keys) and implementing the EFC transactions in each others' RSEs, or they can reach an agreement to

define a new transaction (and contract) that is common to both. Considerations should also be made by

each operator so that the RSE has sufficient resources to implement such additional EFC transactions.

In order to achieve interoperability, operators should agree on issues such as
— which optional features are actually being implemented and used,
— access rights and ownership of EFC application data in the OBE,

— security policy (including encryption algorithms and key management, if applicable),

— operational issues, such as how many receipts may be stored for privacy reasons, how many receipts

are necessary for operational reasons (for example as entry tickets or as proof of payment),

— the agreements needed between operators in order to regulate the handling of different EFC

transactions.

In this edition of this document, users are faced with issues related to backward compatibility. This

issue can be managed by using the following:
— EfcModule ASN.1 module, including a version number;

— Efc-ContextMark (incl. the ContextVersion), denoting the implementation version, provides a

means to ensure co-existence of different implementation versions by means of a look-up table

and associated appropriate transaction processing. This will enable the software of the RSE to

determine the version of the OBE and his capabilty to accept the new features introduced by this

edition of ISO 14906.

Annex A provides the normative ASN.1 specifications of the used data types (EFC action parameters

and attributes).

Annex B presents an informative example of a transaction based on the CARDME specification,

including bit-level specification.

Annex C presents informative examples of EFC transaction types, using the specified EFC functions and

attributes.

Annex D presents an informative mapping table from LatinAlphabetNo2 & 5 to LatinAlphabetNo1 to

ease for a Service Provider the use of LatinAlphabetNo1 to encode an OBE for data available wiitten

with non-Latin1 characters.

SIST EN ISO 14906:2019
ISO 14906:2018(E)

Annex E presents an informative mapping table between EFC vehicle data attributes and European

registration certificates to ease the task of a service provider in the OBE personalisation with vehicle data.

Annex F presents the security calculations according to the data encryption standard (DES). This annex

is based on EN 15509:2014, Annex B.

Annex G presents the security computations examples for DES. This annex is based on EN 15509:2014,

Annex E.

Annex H presents the security calculations for advanced encryption standard (AES). This annex is the

adaptation of EN 15509:2014, Annex B for the case of AES.

Annex I presents the security computations examples for AES. This annex is the adaptation of

EN 15509:2014, Annex E for the case of AES.

This application interface definition can also be used with other DSRC media which do not use a layer 7

according to ISO 15628/EN 12834. Any DSRC medium which provides services to read and write data,

to initialise communication and to perform actions is suitable to be used as a basis for this application

interface. Adaptations are medium specific and are not further covered here. As Annex B describes in

detail a transaction for central account systems, this document can also be used for on-board account

systems, in conjunction with ISO 25110, which provides examples of systems based on on-board

accounts.

Electronic fee collection — Application interface definition
for dedicated short-range communication
1 Scope

This document specifies the application interface in the context of electronic fee collection (EFC)

systems using the dedicated short-range communication (DSRC).

The EFC application interface is the EFC application process interface to the DSRC application layer, as

can be seen in Figure 1 below. This document comprises specifications of:

— EFC attributes (i.e. EFC application information) that can also be used for other applications and/or

interfaces,

— the addressing procedures of EFC attributes and (hardware) components (e.g. ICC and MMI),

— EFC application functions, i.e. further qualification of actions by definitions of the concerned services,

assignment of associated ActionType values and content and meaning of action parameters,

— the EFC transaction model, which defines the common elements and steps of any EFC transaction,

— the behaviour of the interface so as to ensure interoperability on an EFC-DSRC application

interface level.
Figure 1 — The EFC application interface

This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (see ISO/

IEC 7498-1), and it is as such not primarily concerned with the implementation choices to be realised at

either side of the interface.

This document provides security-specific functionality as place holders (data and functions) to enable

the implementation of secure EFC transactions. Yet the specification of the security policy (including

specific security algorithms and key management) remains at the discretion and under the control of

the EFC operator, and hence is outside the scope of this document.
