6.11.4: Support Wide Area Connected Vehicle Communications

This process shall support communications with authenticated applications running in other connected vehicle devices and systems to support Wide Area Information Dissemination. This process represents the center-based processing to ensure that data to be transmitted include a verifiable timestamp, a verifiable geographic location of the sender's origin, and a digital signature. The information may also be encrypted to protect sensitive data content. Similarly, with incoming data, this process shall verify the legitimacy of incoming data in terms of their timestamp, sender's geographic location, and valid digital signature. This process shall interact with a Cooperative ITS Certificate Management System (CCMS) to provision, enroll and receive authentication certificates in order to communicate with other connected vehicle systems. This process shall send notices of misbehaving devices to the CCMS. Upon receipt of a Certificate Revocation List (CRL) from the CCMS this process shall no longer accept messages from those devices as authentic. This process shall monitor the list of retrieved information for other connected vehicle applications/objects for the expiration of either the cyber location or the associated credentialing information. Upon expiration of either cyber location or the associated credentialing information for any "discovered" object, this process shall take appropriate actions to terminate active dialogs with the specific object.

This process is associated with the Wide Area Information Disseminator physical object.

This process is associated with the following application objects:
