Definitions

enrollment cert (Information Flow): A certificate that is used to request authorization certificates and to manage other interactions between an end entity and the CCMS.

Device Configuration Manager (Source Physical Object): The 'device configuration manager' (DCM) is a component of the CCMS that is responsible for bootstrapping an end entity and providing secure connection between the end entity and the enrollment certificate 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).
