10.6.4.1: Support ITS Object Communications

This process shall support communications with authenticated applications running in centers, on field equipment such as roadside equipment (RSE), other vehicles, and personal devices. This process represents the vehicle-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 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. 'ITS Communications Support' provides means to send and receive messages to and from other ITS Objects. It provides mechanisms for scheduling and prioritizing communications traffic. It may also provide relay functions.

This process is associated with the ITS Object physical object.
