Cooperative ITS Credentials Management System --> Wide Area Information Disseminator:
security credential revocations

Definitions

security credential revocations (Information Flow): Certificate Revocation List; lists the certificates whose trust has been revoked by the CCMS.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.

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.
