US: SAE Other J2735 - Secure Internet (ITS)

Description:

This solution is used within the U.S.. It combines standards associated with US: SAE Other J2735 with those for I-I: Secure Internet (ITS). The US: SAE Other J2735 standards include upper-layer standards required to implement V2X information flows that do not yet have fully specified functionality and performance charcateristics. 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.

Comm Profile: I-I: Secure Internet (ITS)

Standards in Profile:

Level	Standard	Description
Access	Internet Subnet Alternatives	A set of alternative standards that includes any Subnet Layer method of connecting to the Internet.
Mgmt	Bundle: SNMPv3 MIB	A bundle of standards (RFCs) that groups the common management information bases (MIBs) used to manage IP networks at the transport layer and below using SNMPv3.
Security	Secure Session Alternatives	A set of alternative standards that identifies standards that are used to establish and maintain secure Internet sessions. If an information exchange does not require encryption, the (D)TLS session can negotiate NULL encryption. NOTE: If TCP is selected in the TransNet Layer, one of the TLS alternatives must be selected from this alternative set; if UDP is selected in the TransNet Layer, one of the DTLS alternatives must be selected from this alternative set.
TransNet	Internet Transport Alternatives	A set of alternative standards that identifies the two major options for the transport layer for mainstream IP-based deployments.
TransNet	IP Alternatives	A set of alternative standards that allows for the selection of IPv4 or IPv6.

Data Profile: US: SAE Other J2735

Standards in Profile:

Level	Doc #	Standard	Description
Facilities	SAE J2735	SAE J2735 DSRC Message Set	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 Entity	SAE J2735	SAE J2735 DSRC Message Set	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.

Readiness Description:

Two significant or one significant and several 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. 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.
