security credentials revocation information Quintuple

Bidirectional?: False

security credentials revocation information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'CCMS Revocation', and 'Personal Trust Management'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Cooperative ITS Credentials Management System' to 'Personal Information Device'.

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 Revocation (Source Application Object): "CCMS Revocation" components generate the internal blacklist and Certificate Revocation List (CRL) and distribute them to other CCMS components and end entities. Once placed on the CRL, an end entity is in the Unauthorized state. Once placed on the blacklist, an end entity is in the Unenrolled state.

Personal Information Device (Destination Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with connected vehicle on-board equipment.

Personal Trust Management (Destination Application Object): "Personal Trust Management" manages the certificates and associated keys that are used to sign, encrypt, decrypt, and authenticate messages. It communicates with the Security and 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.
