authorization coordination Quintuple

Bidirectional?: True

authorization coordination (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'CCMS Authorization' application object and the 'Other CCMS' physical object. In this case, there is only a single Layer 2 flow associated with this interconnect, so the Layer 1 application interconnect name and the Layer 2 information flow name are both 'authorization coordination'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

Other CCMS (Source Physical Object): Representing another Cooperative ITS Credentials Management System (CCMS), 'Other CCMS' 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.

Cooperative ITS Credentials Management System (Destination 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.

CCMS Authorization (Destination Application Object): "CCMS Authorization" components provide authorization credentials (e.g., pseudonym certificates) to end entities. The end entity applies for and obtains authorization credentials, enabling the end entity to enter the "Operational" state. This function requires an interactive dialog, including at minimum a Certificate Request from the end entity desiring certificates. This request will be checked for validity, with the embedded enrollment certificate checked against an internal blacklist. If all checks are passed, this function will distribute a bundle of linked pseudonym certificates suitable for use by the requesting end entity, with the characteristics and usage rules of those certificates dependent on the operational policies of the CCMS. It also provides the secure provisioning of a given object's Decryption Key in response to an authorized request from that object. The retrieved Decryption Key will be used by the receiving object to decrypt the "next valid" batch within the set of previously retrieved Security Credential batches.
