Cooperative ITS Credentials Management System --> Other Credentials Management Systems:
enrollment coordination

This triple is bi-directional. See also Other Credentials Management Systems --> Cooperative ITS Credentials Management System: enrollment coordination

Definitions

enrollment coordination (Information Flow): Sharing of enrollment policies, certification mechanisms, registration and deregistration identifier types, registered and deregistered end entities, and other information that supports enrollment process coordination with another CCMS.

Cooperative ITS Credentials Management System (Source Physical Object): The 'Cooperative ITS Credentials Management System' (CCMS) is a high-level aggregate representation of the interconnected systems that enable trusted communications between mobile devices and other mobile devices, roadside devices, and centers and protect data they handle from unauthorized access. Representing the different interconnected systems that make up a Public Key Infrastructure (PKI), this physical object represents an end user view of the credentials management system with focus on the exchanges between the CCMS and user devices that support the secure distribution, use, and revocation of trust credentials.

Other Credentials Management Systems (Destination Physical Object): Representing another Cooperative ITS Credentials Management System (CCMS), 'Other Credentials Management Systems' is intended to provide a source and destination for information exchange between peer credentials management systems. It supports modeling of projects or regions that include multiple interconnected CCMS that manage credentials distribution and management in the connected vehicle environment.

Communication Solutions

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

Selected Solution

(None-Security-Management) - Guaranteed 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-Security-Management) with those for I-I: Guaranteed Secure Internet (ITS). The (None-Security-Management) standards include an unspecified set of upper-layer standards required to define security management. 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.

Basis Coordination of credentialing and revocation should be maintained between the trust authorities and no one else. Outside observers may learn CCMS behaviors and may gain understanding of the timings between revocation/granting at one authority vs. propogation to another, which may enable attacks. Coordination of credentialing and revocation needs to be correct at all times, or trust/lack-of-trust may not be correctly propagated and end entities improperly served. Depending on the scale of the integrity/availability failure, this could affect a small or large amount of the C-ITS environment.
