Identifier Registry --> Cooperative ITS Credentials Management System:
service identifiers
Definitions
service identifiers (Information Flow): Identifiers assigned to particular services, and the context necessary when and how to use these identifiers.
Identifier Registry (Source Physical Object): The 'Identifier Registry' maintains identifiers that must be unique to facilitate interoperability in the connected vehicle environment.
Cooperative ITS Credentials Management System (Destination 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.

| Basis | Likely openly published information. | Identifiers are used with associated permissions to determine who/what can perform various activities. A compromise in this information would significantly compromise all of C-ITS that was affected. | Identifiers are expected to be updated infrequently, thus requiring only intermittent connectivity to the CCMS. | |
