(None-Data) - Local Unicast Wireless (1609.2)

Description

This solution is used within the U.S.. It combines standards associated with (None–Data) with those for V–X: Local Unicast Wireless (1609.2). The (None–Data) standards include an unspecified set of standards at the upper layers. The V–X: Local Unicast Wireless (1609.2) standards include lower–layer standards that support local–area unicast wireless solutions applicable to North America, such as WAVE DSRC, LTE–V2X, LTE, Wi–Fi, etc.

Includes Standards

Level	DocNum	FullName	Description
Mgmt	Addressed Elsewhere	Addressed Elsewhere in Stack	The services related to this portion of the stack are defined in the other standards listed for this solution.
Security	IEEE 1609.2	IEEE Standard for Wireless Access in Vehicular Environments – Security Services for Applications and Management Messages	This standard defines secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages. It also describes administrative functions necessary to support the core security functions.
Security	IEEE 1609.2a	IEEE 1609.2a–2017 – IEEE Standard for Wireless Access in Vehicular Environments––Security Services for Applications and Management Messages – Amendment 1	This standard defines secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages. It also describes administrative functions necessary to support the core security functions.
Security	IEEE 1609.2b	IEEE Standard for Wireless Access in Vehicular Environments––Security Services for Applications and Management Messages – Amendment 2––PDU Functional Types and Encryption Key Management	This standard defines secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages. It also describes administrative functions necessary to support the core security functions.
ITS Application Entity		Standard(s) need to be developed	One or more standards need to be developed for this subject matter before this is considered a complete solution.
Facilities		Standard(s) need to be developed	One or more standards need to be developed for this subject matter before this is considered a complete solution.
TransNet	IEEE 1609.3	IEEE Standard for Wireless Access in Vehicular Environments (WAVE) – Networking Services	This standard defines the network and transport layer options for the WAVE environment. The standard defines three options: a bandwidth efficient single–hop solution known as WSMP, UDP/IP, and TCP/IP. It has been harmonized with ISO FNTP and FSAP – a common message format specified in ISO 16460.
Access	IEEE 802.11	IEEE Draft Standard for Information technology––Telecommunications and information exchange between systems Local and metropolitan area networks––Specific requirements Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specificatio	This standard defines the physical and data link layers for wireless Ethernet, including WiFi and DSRC.

Readiness: Lowest

Readiness Description

Many serious issues. This category includes solutions that have not been standardized, or do not have a basic level of interoperability or security. Consider selecting a different communications solution or if this is not possible (eg. a pilot of a new application that has not been standardized), take additional measures to provide an acceptable level of security or interoperability.

Issues

Issue	Severity	Description	Associated Standard	Associated Triple
Data profile not defined	Ultra	Performance, functionality, and the upper–layers of the OSI stack have not been defined for this information flow.	(None)	(All)
Identifier registry does not exist	Medium	The standard defines a field which requires a globally unique identifier, but no registration authority exists to assign these values.	(None)	Commercial Vehicles=>unique identifiers=>OSHP Weigh–in–Motion Stations
Uncertainty about trust revocation mechanism	Medium	The mechanisms used to prevent bad actors from sending authorized messages is unproven.	Bundle: IEEE 1609.2	(All)
