Definitions

enrollment credentials (Information Flow): Long-term security credentials such as 'enrollment certificates' that demonstrate the trust-worthiness of the source device or application.

Cooperative ITS Credentials Management System (Source Physical Object): The 'Cooperative ITS Credentials Management System' (CCMS) is a high-level aggregate representation of the interconnected systems that enable trusted communications between mobile devices and other mobile devices, roadside devices, and centers and protect data they handle from unauthorized access. Representing the different interconnected systems that make up a Public Key Infrastructure (PKI), this physical object represents an end user view of the credentials management system with focus on the exchanges between the CCMS and user devices that support the secure distribution, use, and revocation of trust credentials.

ITS Object (Destination Physical Object): The general 'ITS Object' includes core capabilities common to any class of object.

Communication Solutions

US: Device enrollment - Secure Internet (ITS) (3)
(None-Data) - Secure Internet (ITS) (32)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: Device enrollment - Secure Internet (ITS)

Solution Description

This solution is used within the U.S.. It combines standards associated with US: Device enrollment with those for I-I: Secure Internet (ITS). The US: Device enrollment standards include upper-layer standards required to support device enrollment services. 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.

Basis	Credentials need to be delivered to their intended target only. Interception and potential use by a third party compromises the C-ITS trust model.	Credentials need to be correct and intact on delivery, or they will not be functional. Without functional credentials, the end entity cannot operate.	Credentials will be granted as needed but generally not in real-time with operations; that is, an end entity will request credentials a significant time in advance of actually needing them for providing user services.
