Identifier Registry --> Intermediate CA:
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.

Intermediate CA (Destination Physical Object): An 'intermediate certificate authority' (ICA) is a certificate authority (CA) whose certificate was issued by another CA and whose main responsibility is to issue certificates to another CA; that is, an authorization certificate authority, and enrollment certificate authority or another ICA.

Interoperability Description
Regional Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Rating Low High Low
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.
