US: WZDx - Guaranteed Secure Internet (ITS)
Description:
This solution is used within the U.S.. It combines standards associated with US: WZDx with those for I-I: Guaranteed Secure Internet (ITS). The US: WZDx standards include upper-layer standards required to implement work zone information data exchanges. The I-I: Guaranteed Secure Internet (ITS) standards include lower-layer standards that support secure communications with guaranteed delivery between ITS equipment using X.509 or IEEE 1609.2 security certificates.

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.

IETF RFC 793
|
IETF RFC 793 TCP
|
This standard (RFC) defines the main connection-oriented Transport Layer protocol used on Internet-based networks.

IP Alternatives
|
A set of alternative standards that allows for the selection of IPv4 or IPv6.

IETF RFC 7159 JSON
|
The JavaScript Object Notation (JSON), a lightweight, text-based, language-independent data interchange format. It was derived from the ECMAScript Programming Language Standard. JSON defines a small set of formatting rules for the portable representation of structured data. This document removes inconsistencies with other specifications of JSON, repairs specification errors, and offers experience-based interoperability guidance.

This standard defines a common format for exchanging work zone information.

Readiness Description:
One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
