Definitions

registered EEs (Information Flow): List of registered end entities and/or end entities receiving auth tokens for non-security critical interactions with CCMS.

Supplementary Authorization Server (Source Physical Object): The 'supplementary authorization server' is a component of the CCMS that provides authorization tokens to end entities for use in authorizing operations that are not critical for security.

Registration Authority (Destination Physical Object): The 'Registration Authority' (RA) is a component of the CCMS that is the main point of contact for an end entity, and is responsible for provisioning the end entity with authorization and successor enrollment

Communication Solutions

(None-Data) - Secure Internet (ITS) (43)

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

Selected Solution

(None-Data) - Secure Internet (ITS)

Solution Description

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for I-I: Secure Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. 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.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

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).
