US: SAE Weather Info - Secure Wireless Internet (ITS)


This solution is used within the U.S.. It combines standards associated with US: SAE Weather Info with those for I–M: Secure Wireless Internet (ITS). The US: SAE Weather Info standards include upper–layer standards required to implement V2X weather information flows. The I–M: Secure Wireless Internet (ITS) standards include lower–layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non–mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Includes Standards

MgmtIETF RFC 3413Simple Network Management Protocol (SNMP) ApplicationsThis standard (RFC) includes MIBs that allow for the configuration and management of remote Targets, Notifications, and Proxys.
MgmtIETF RFC 3414User–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.
MgmtIETF RFC 3415View–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.
MgmtIETF RFC 3416Version 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.
MgmtIETF RFC 3418Management Information Base (MIB) for the Simple Network Management Protocol (SNMP)This standard (RFC) defines the MIB to configure and manage an SNMP entity.
MgmtIETF RFC 4293Management Information Base for the Internet Protocol (IP)This standard (RFC) defines the MIB that manages an IP entity.
SecurityIETF RFC 5280Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) ProfileThis standard (RFC) defines how to use X.509 certificates for secure communications over the Internet.
SecurityIETF RFC 8446The Transport Layer Security (TLS) ProtocolThis 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 EntitySAE J2735Dedicated Short Range Communications (DSRC) Message Set Dictionary (TM)This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
ITS Application EntitySAE J2945/1On–Board System Requirements for V2V Safety CommunicationsThis standard specifies the system requirements for an on–board vehicle–to–vehicle (V2V) safety communications system for light vehicles, including standards profiles, functional requirements, and performance requirements.
ITS Application EntitySAE J2945/3Requirements for V2I Weather ApplicationsThis document specifies interface requirements between vehicles and infrastructure for weather applications, including detailed systems engineering documentation (needs and requirements mapped to appropriate message exchanges). The purpose of this SAE Standard is to enable interoperability supporting these weather applications over a communications technology agnostic interface.
FacilitiesSAE J2945Dedicated Short Range Communication (DSRC) Systems Engineering Process Guidance for J2945/x Documents and Common Design ConceptsThis standard defines cross–cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content.
TransNetIETF RFC 2460Internet Protocol, Version 6 (IPv6) SpecificationThis standard (RFC) specifies version 6 of the Internet Protocol (IPv6), also sometimes referred to as IP Next Generation or IPng.
TransNetIETF RFC 4291IP Version 6 Addressing ArchitectureThis 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.
TransNetIETF RFC 4443Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) SpecificationThis standard (RFC) defines the control messages to manage IPv6.
TransNetIETF RFC 793Transmission Control ProtocolThis standard (RFC) defines the main connection–oriented Transport Layer protocol used on Internet–based networks.

Readiness: High

Readiness Description

A small number of minor issues. For existing deployments, consider addressing issues as needed as part of maintenance or upgrade activities. For new deployments, the solution is likely suitable for wide–scale deployment when applied to the triples it supports, though the noted issues should be considered and a path to addressing them developed, if needed, either as part of design or subsequent maintenance or upgrade activities.
