Location Obscurer Proxy --> ITS Object:
CA certs

Definitions

CA certs (Information Flow): One or more signed and current certificates of certificate authorities (CA) within the CCMS PKI structure.

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

  • US: Security Credentials - Secure Internet (ITS) (0)
Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: Security Credentials - Secure Internet (ITS)

Solution Description

This solution is used within the U.S.. It combines standards associated with US: Security Credentials with those for I-I: Secure Internet (ITS). The US: Security Credentials standards include upper-layer standards required to provide and revoke security credentials, define security policy, and handle enrollment coordination. 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).

Basis By definition this is public information. These certificates are used by end entities to verify the entire trust chain and are thus fundamental to any application depending on PKI-enabled trust. While this material must be present on all end entity devices, the flow will be infrequently used by any given device.
