Introduction
Classification and management of ITS applications in a global context covers more than just the ITS
applications themselves. It also covers elements of the environment in which ITS applications are
instantiated.
Intelligent Transport Systems (ITS) provide ITS services to users by execution of ITS applications which
typically requires communications between ITS station application processes residing in ITS station
units (ITS-SU). Communications includes exchange of messages dedicated to ITS applications, and
exchange of messages from ITS message sets.
ITS applications and ITS application classes are referred to as ITS application objects. ITS application
objects are uniquely identified by the registered “ITS Application Identifier” (ITS-AID) specified in this
Technical Specification.
NOTE An ITS application class groups ITS applications together that provide the same type of service,
e.g. “Electronic Fee Collection” (EFC), but operate in different contexts. The definition of ITS application
classes is based on the concept of the DSRC Application entity as introduced in Reference [4], which is
identified by a DSRCApplicationEntityID.
In Reference [17] ITS message sets were referred to as ITS application objects. This definition is not
adopted in this Technical Specification due to the fundamentally different nature of ITS message sets
and ITS application objects. ITS message sets are uniquely identified by the registered “ITS Message Set
Identifier” (ITS-MsgSetID) specified in this Technical Specification.
This Technical Specification is an extension towards more general and global applicability of Reference
[17]. This Technical Specification introduces the term “ITS-S object” as a general reference to ITS
application objects, ITS message sets and other objects that may require globally unique identification
and registration.
NOTE Examples of other ITS-S objects are ITS-S communication protocols and ITS-S security protocols.
[6][7][8][9]
Management of ITS-S objects is specified in the ISO 24102 series of International Standards
[10][11]
and in the Technical specification ISO/TS 17423. This Technical Specification focuses on some
management aspects related to authorized and controlled operation of ITS-S objects which requires
considerations of ITS-S object identifiers, i.e. ITS-AID, ITS-MsgSetID, ITS-SUID, ITS-SCUID, addresses
and protocol identifiers used in the communication protocol stack of an ITS-S, and others.

5 Application management
This is an informative clause.
5.1 Introduction
In this Technical Specification, application management refers to objects and procedures, both internal
and external to the platforms on which the applications are installed, that are used to ensure the efficacy
and authenticity of these applications and these platforms. Platforms in this context are ITS station
1)
communication units (ITS-SCUs) and applications are ITS-S application processes as specified in
ISO 21217. Distinction is made between authorized applications and permitted applications. Application
management procedures involve protocols for exchanging information between the various entities
involved in application management, and these procedures are described at a functional level in this
Technical Specification. These procedures are to be used for authorizing and authenticating the use of
ITS-S application entities over communication networks. The architecture of this network described in
ISO 21217 and in 5.2.
Entities related to ITS application management in the global context and their roles identified and / or
specified in this Technical Specification are listed in Table 1.

fiers.
ITS trusted authority Entity in charge of providing ITS-S object security credentials such as keys and
certificates for hardware and software.
5.2 ITS communications architecture
As illustrated in Figure 1, regardless of the complexity of the networks employed, communication between
“ITS station units” (ITS-SUs), and between ITS-SUs and other types of ITS communication nodes, is on a
peer-to-peer basis. The distinguishing feature of ITS-SUs is that of trust and authentication as discussed
in 5.5.1. The need for trust and authentication arises from the deployment of critical safety-of-life and
property applications. This leads to the definition of an ITS station as a “Bounded Secured Managed
Domain” (BSMD) as specified in ISO 21217, and the requirement for a “Public Key Infrastructure” (PKI)
for trust assertion and certificate management.

---------------------- Page: 11 ----------------------
ISO/TS 17419:2014(E)
Figure 1 — Simplified ITS peer-to-peer communication architecture
5.3 PKI architecture
A public-key infrastructure (PKI) is a system for the creation, storage, distribution and revocation of
digital certificates which are used to verify that a particular public key and associated rights belong to
a certain entity. A PKI creates digital certificates which map public keys to entities and their rights. It
securely stores these certificates in a central repository and revokes them if needed.
5.4 Regulations and policies
Application management procedures must comply with applicable regulation and use applicable policies.
A policy is a set of rules related to a particular purpose. Such a rule can be expressed as an obligation, an
authorization, a permission, or a prohibition. A regulation is an enforceable policy. Regulations apply to
a specific regulatory domain and are produced and maintained by regulators. Policies apply to a specific
policy domain.
The need and applicability for regulations and policies in ITS is identified in this Technical Specification
for the following purposes:
— radio frequency allocation and usage;
— privacy issues;
— road traffic circulation;
— communication networks.
A regulatory region is uniquely identified by an ITS Regulatory Region Identifier ITS-RRID.
A policy region is uniquely identified by an ITS Policy Region Identifier ITS-PRID.
5.5 ITS station
5.5.1 ITS station architecture
The architecture of the ITS station (ITS-S) specified in ISO 21217 is illustrated in Figure 2.

---------------------- Page: 12 ----------------------
ISO/TS 17419:2014(E)
Figure 2 — ITS station architecture (from ISO 21217)
The term ITS-S refers to functionalities rather than a physical unit. Six functional blocks of an ITS-S are
distinguished in Figure 2:
Applications
— ITS-S applications
Communications
— Data plane
— “Access”: ITS-S access layer, i.e. OSI layers one and two.
— “Networking & Transport”: ITS-S networking & transport layer, i.e. OSI layers three and four.
— “Facilities”: ITS-S facilities layer, i.e. OSI layers five, six and seven.
— Management entity
— “Management”: ITS-S management entity
8 © ISO 2014 – All rights reserved
---------------------- Page: 13 ----------------------
ISO/TS 17419:2014(E)
— “Security”: ITS-S security entity
These entities are assumed to interact with each other within a “Bounded Secured Managed Domain”
(BSMD). Implementation and maintenance of these entities in a standard compliant manner creates ITS-S
objects, ITS-SUs and ITS-SCUs that can be trusted to operate according to the policies and procedures
assigned to them by trusted authorities. It is precisely the attribute of trust within the ITS domain
that distinguishes ITS-SUs (Bounded Secured Managed Entities, BSMEs) from all other communication
nodes. As a managed domain, elements of the ITS-S need to be aware of and interact with the ITS-S
management entity. As a secured domain, installation (e.g. “plug-and-play”) of an element of an ITS-S
such as an ITS-S application, communication interface, or a communication protocol must be performed
in a controlled and secure manner, applying the procedures for registration of identifiers of ITS-S objects
and the authentication of registered elements at time of installation.
ITS-S applications interact with the “Communications” block via an “Application Programming Interface”
(API). This interaction may address either protocols in the ITS-S facilities layer of the data plane, or
protocols in the ITS-S management entity or ITS-S security entity.
ITS-S access and ITS-S networking & transport layers are used by ITS-S facilities layer services and
ITS-S applications to transmit and receive ITS-NTSDUs as described in ISO 21217.
A specific combination of an ITS-S networking & transport layer protocol (residing in an instantiation of
the ITS-S networking & transport layer), a “Communication Interface” (CI) (residing in an instantiation
of the ITS-S access layer), an ITS-S facilities layer protocols (optional) and related necessary management
and security protocols (optional) is referred to as an ITS-S communication protocol stack specified in
ISO/TS 17423. An ITS-S communication profile, which is a parameterized ITS-S communication protocol
[11]
stack specified in ISO/TS 17423 is associated with a communication path. An ITS-S application
process may use more than one ITS-S communication profile, e.g. one ITS-S communication profile for
each of its distinct communication sources (flows). Further details on the automatic selection of ITS-S
communication profiles are found in ISO/TS 17423.
5.5.2 Instantiations of an ITS station
The functionality of an ITS-S may be implemented in one or more “ITS-S Communication Units”
(ITS-SCU) as explained in ISO 21217. For example, an ITS-S can be implemented by connecting units
containing ITS-S router functionality and ITS-S host functionality using a local network (called an ITS
station-internal network). An implementation of an ITS station is referred to as an “ITS-S unit” (ITS-SU).
An ITS-SU is uniquely identified by an ITS-SUID. An ITS-SCU is uniquely identified by an ITS-SCUID. An
ITS-SU comprised of more than one ITS-SCU has a master ITS-SCU. The ITS-SUID is derived from the
ITS-SCUID of the master ITS-SCU as specified in 7.1.7.
An ITS-SCU is assigned to one “ITS-SCU Configuration Management Centre” (I
