Field Maintenance Equipment --> Connected Vehicle Roadside Equipment:
RSE application install/upgrade
Definitions
RSE application install/upgrade (Information Flow): This flow supports remote installation and update of software applications residing in the RSE. It supports transmission of the secure software installation files, including executable application code and associated support files.
Field Maintenance Equipment (Source Physical Object): 'Field Maintenance Equipment' represents the portable equipment used by field personnel to locally troubleshoot, initialize, reprogram, and test infrastructure equipment. It may include a laptop, specialized diagnostics tools, or any other general purpose or specialized equipment that is interfaced locally to infrastructure equipment to support maintenance and repair.
Connected Vehicle Roadside Equipment (Destination Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. 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.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | RSE control, configuration and software/firmware update should all be protected from view. A hostile third party could use this information to reverse engineer control/configuration/update processes, and use that information in an attack across a broad swatch of infrastructure, which would have severe effects to the connected vehicle infrastructure. | RSE control, configuration and update need to be correct or the RSE may be misconfigured, which for some applications could have severe safety impacts. | RSE control, configuration and update needs to be available; field versions of these flows should always be available, which is why they are higher than the C2I versions. |
