Definitions

permission request received (Information Flow): An acknowledgement that the permission request or permission update request was received.

Authorizing Center (Source Physical Object): The 'Authorizing Center' provides the functionality needed to enable data exchange between and among mobile and fixed transportation users. Its primary mission is to enable safety, mobility and environmental communications-based applications for both mobile and non-mobile users. The Authorizing Center has some jurisdiction over limited access resources; typically this includes roadside application access and radio spectrum licensing. It may be implemented as an autonomous center or as a set of supporting services that are co-located within another center.

Center (Destination Physical Object): This general physical object is used to model core capabilities that are common to any center.

Communication Solutions

(None-Data) - Guaranteed Secure Internet (ITS) (32)

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) - Guaranteed Secure Internet (ITS)

Solution Description

This solution is used within Australia, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for I-I: Guaranteed Secure Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. The I-I: Guaranteed Secure Internet (ITS) standards include lower-layer standards that support secure communications with guaranteed delivery 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).

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	High	High	High
Basis	End entity identity and associated permissions could be contained. This PII could include that of emergency personnel, and could include permissions assigned, all of which, if easily accessed could have a high cost of recover. Flow is not realized by known standards, so it may be possible to lower it to MODERATE in the future, when it can be better characterized.	Assignment of permissions with control over physical communications channels needs the greatest possible protection and cannot be mishandled or manipulated in transit.	While update of this flow may be important, it is a non-real-time service in most cases. Could possibly be LOW.
