US: TCIP - Secure Internet (ITS)

Description

This solution is used within the U.S.. It combines standards associated with US: TCIP with those for I–I: Secure Internet (ITS). The US: TCIP standards include upper–layer standards required to implement transit–related communications. The I–I: Secure Internet (ITS) standards include lower–layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Includes Standards

Level	DocNum	FullName	Description
Mgmt	IETF RFC 3411	An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks	This standard (RFC) defines the basic architecture for SNMPv3 and includes the definition of information objects for managing the SNMP entity's architecture.
Mgmt	IETF RFC 3412	Message Processing and Dispatching for the Simple Network Management Protocol (SNMP)	This standard (RFC) contains a MIB that assists in managing the message processing and dispatching subsystem of an SNMP entity.
Mgmt	IETF RFC 3413	Simple Network Management Protocol (SNMP) Applications	This standard (RFC) includes MIBs that allow for the configuration and management of remote Targets, Notifications, and Proxys.
Mgmt	IETF RFC 3414	User–based Security Model (USM) for version 3 of the Simple Network Management Protocol (SNMPv3)	This standard (RFC) contains a MIB that assists in configuring and managing the user–based security model.
Mgmt	IETF RFC 3415	View–based Access Control Model (VACM) for the Simple Network Management Protocol (SNMP)	This standard (RFC) contains a MIB that supports the configuration and management of the View–based access control model of SNMP.
Mgmt	IETF RFC 3416	Version 2 of the Protocol Operations for the Simple Network Management Protocol (SNMP)	This standard (RFC) defines the message structure and protocol operations used by SNMPv3.
Mgmt	IETF RFC 3418	Management Information Base (MIB) for the Simple Network Management Protocol (SNMP)	This standard (RFC) defines the MIB to configure and manage an SNMP entity.
Mgmt	IETF RFC 4293	Management Information Base for the Internet Protocol (IP)	This standard (RFC) defines the MIB that manages an IP entity.
Security	IETF RFC 5280	Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile	This standard (RFC) defines how to use X.509 certificates for secure communications over the Internet.
Security	IETF RFC 8446	The Transport Layer Security (TLS) Protocol	This standard (RFC) specifies Version 1.3 of the Transport Layer Security (TLS) protocol. The TLS protocol provides communications security over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.
ITS Application Entity	APTA TCIP–S–001 Vol 2	Transit Communications Interface Profiles – TCIP Data and Dialog Definitions	This standard defines the data concepts used by the TCIP standard.
Facilities	W3C XML	Extensible Markup Language (XML) 1.0 (Fifth Edition)	This standard defines a generic markup language that can be used to share customizable information by using start and stop tags within the text.
Facilities	APTA TCIP–S–001 Vol 2	Transit Communications Interface Profiles – TCIP Data and Dialog Definitions	This standard defines the data concepts used by the TCIP standard.
TransNet	IETF RFC 2460	Internet Protocol, Version 6 (IPv6) Specification	This standard (RFC) specifies version 6 of the Internet Protocol (IPv6), also sometimes referred to as IP Next Generation or IPng.
TransNet	IETF RFC 4291	IP Version 6 Addressing Architecture	This standard (RFC) defines the addressing architecture of the IP Version 6 (IPv6) protocol. It includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses.
TransNet	IETF RFC 4443	Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification	This standard (RFC) defines the control messages to manage IPv6.
TransNet	IETF RFC 793	Transmission Control Protocol	This standard (RFC) defines the main connection–oriented Transport Layer protocol used on Internet–based networks.
Access		Internet Subnet Alternatives	A set of alternative standards that includes any Subnet Layer method of connecting to the Internet.

Readiness: Moderate–Low

Readiness Description

Multiple significant and minor issues.  For existing deployments, the chosen solution is likely deficient in security or management capabilities, and the issues should be reviewed and upgrades developed as needed. Some solutions in this category may also be becoming obsolete from an interoperability perspective and if this is the case, then upgrades should be planned as soon as possible. For new deployments, the solution may be viable for pilots when applied to the triples it supports; such pilot deployments should consider a path to addressing these issues as a part of their design activities. The solution does not provide sufficient interoperability, management, and security to enable proper, full–scale deployment without  additional work.

Issues

Issue	Severity	Description	Associated Standard	Associated Triple
Encoding rules not defined	High	The standards do not unambiguously define which set of encoding rules to use.	(None)	(All)
Out of date (medium)	Medium	The standard includes normative references to other standards that have been subject to significant changes that can impact interoperability or security of systems and the industry has not specified if and how these updates should be implemented for deployments of this standard.	TCIP – Data	(All)
Secure data access not provided	Medium	The solution does not define rules on how the application entity authenticates requests to accept or provide data.	(None)	(All)
Data not defined in standard format	Low	The definition of data concepts should conform to ISO 14817–1 to promote reuse among ITS.	TCIP – Data	(All)
