security credentials enrollment information Quintuple
Bidirectional?: True
security credentials enrollment information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'CCMS Enrollment', and 'WAID Trust Management'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.
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.
CCMS Enrollment (Source Application Object): "CCMS Enrollment" components provide enrollment credentials to end entities. The end entity applies for and obtains enrollment credentials that can be used to communicate with other CCMS components, entering the "Unauthorized" state. CCMS Enrollment components also participate in de-registration processes through interaction with CCMS Revocation components.
Wide Area Information Disseminator (Destination Physical Object): The 'Wide Area Information Disseminator' represents the Connected Vehicle center based systems and communications equipment that is used to send messages to equipped vehicles using wide-area wireless communications such as satellite radio, terrestrial FM broadcast subcarrier, or cellular data networks.
WAID Trust Management (Destination Application Object): 'WAID Trust Management' manages the certificates and associated keys that are used to sign, encrypt, decrypt, and authenticate messages. It communicates with the Cooperative ITS Credentials Management System to maintain a current, valid set of security certificates and identifies, logs, and reports events that may indicate a threat to the Connected Vehicle Environment security.
