protected location and address flow Quintuple

Bidirectional?: False

protected location and address flow (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'RSE Privacy Services', and 'Center Trust Management'. 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 'protected location and address flow'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Roadside Equipment' to 'Center'.

Roadside Equipment (Source Physical Object): 'Roadside Equipment' (RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.

RSE Privacy Services (Source Application Object): "RSE Privacy Services" operates as a proxy, replacing the mobile device's network address with the RSE's, and tagging the message so that it can return replies to the mobile device.

Center (Destination Physical Object): This general physical object is used to model core capabilities that are common to any center.

Center Trust Management (Destination Application Object): "Center 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.
