Toledo Regional ITS Architecture (2021)

ITS Communications Equipment

Status: Planned

Description

This element includes the communications hardware and software that supports secure, reliable communications. It provides the layered protocols and communications services and includes the physical network plant and network hardware that supports ITS communications. It also encompasses security services that protect communications and the management services that support network management. This element allows transportation stakeholders that are implementing their own communications solution to represent this implementation in their ITS architecture. The communications capabilities provided by this element are frequently purchased from a third party provider. When communications is a purchased service, the hardware and software included in this element are largely transparent to transportation stakeholders and may be transparent to the ITS architecture.

Functional Objects

Functional Object	Description	User Defined
ITS Communications Privacy Protection	'ITS Communications Privacy Protection' operates as a proxy, obscuring the originator's network address, and tagging the message so that it can return replies to the originator.	False
ITS Communications Services	'ITS Communications Services' supports secure, reliable data communications between connected devices. It includes the network devices as well as any required physical cabling and supporting hardware that represent the communications infrastructure that originate, route, and terminate data communications between a source and a destination. Applications specific protocols are layered over more general communications protocols to support the communications. Network management keeps the network configured and working reliably. Security services ensure the data received is correct and from an authentic source.	False
ITS Communications Support	'ITS Communications Support' provides means to send and receive messages to and from other ITS Objects. It provides mechanisms for scheduling and prioritizing communications traffic. It may also provide relay functions.	False

Physical Standards

Document Number	Title	Description
ISO 21217	Intelligent transport systems –– Communications access for land mobiles (CALM) –– Architecture	ISO 21217 describes the communications reference architecture of nodes called "ITS station units" designed for deployment in ITS communication networks. While it describes a number of ITS station elements, whether or not a particular element is implemented in an ITS station unit depends on the specific communication requirements of the implementation. It also describes the various communication modes for peer–to–peer communications over various networks between ITS communication nodes. These nodes may be ITS station units as described in the document or any other reachable nodes. ISO 21217 specifies the minimum set of normative requirements for a physical instantiation of the ITS station based on the principles of a bounded secured managed domain.
NIST FIPS PUB 140–2	Security Requirements for Cryptographic Modules	This Federal Information Processing Standard (140–2) specifies the security requirements that will be satisfied by a cryptographic module, providing four increasing, qualitative levels intended to cover a wide range of potential applications and environments. The areas covered, related to the secure design and implementation of a cryptographic module, include specification; ports and interfaces; roles, services, and authentication; finite state model; physical security; operational environment; cryptographic key management; electromagnetic interference/electromagnetic compatibility (EMI/EMC); self–tests; design assurance; and mitigation of other attacks.
