Definitions

CCMS policies (Information Flow): A set of requirements defining the operation of the CCMS. This may include both machine and human-interpretable content, describing various aspects of CCMS operations including identification and authentication methods of entities performing PKI roles (e.g., electors, certificate authorities), minimum security-related requirements for each role (e.g., personnel controls, network security controls etc.), definition of operational practices related to registration of new and de-registration of old certificates, specification of the certificate trust list (CTL) format and lifecycle management, management of the revocation of trust, and management of distributed credentials (e.g., lifecycle of enrollment, authorization certificates).

Location Obscurer Proxy (Source Physical Object): The 'location obscurer proxy' (LOP) is a component of the CCMS that is responsible for hiding location information of an end entity from the registration authority.

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

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).

Rating	Not Applicable	High	Moderate
Basis	By definition this is public information.	Policies impact behavior, action and repurcussions. This information must be correct and coherent to avoid misunderstandings that might remove an entity from the trusted environment.	While this material must be present on all end entity devices, the flow will be infrequently used by any given device.
