It may include a hardware security module and security management information base. | False |
|---|
| RSE Data Subscription Management | 'RSE Data Subscription Management' manages data subscriptions for an RSE. It provides access to a catalog of available data, manages the necessary identification information and rules that govern the data subscriptions, supports communications with data providers to collect data per the subscription rules, and makes the data available to other RSE applications. It supports different mechanisms for collecting data including one–time query–response as well as publish–subscribe services. | False |
|---|
| RSE Device Management | 'RSE Device Management' provides executive control and monitoring of the RSE hardware and installed software applications. It monitors the operational status of the hardware and other attached field devices and detects and reports fault conditions. A back office interface supports application installation, upgrade, and configuration as well as remote control of the operating mode and hardware configuration settings and initiation of remote diagnostics. A local interface is provided to field personnel for local monitoring and diagnostics, supporting field maintenance, repair, and replacement. | False |
|---|
| RSE Map Management | 'RSE Map Management' provides the map functionality necessary to support map data updates to passing vehicles. It collects current map and geometry data and provides current map and geometry data to connected vehicles. | False |
|---|
| RSE Parking Management | 'RSE Parking Management' monitors the basic safety messages generated by connected vehicles to detect vehicles parking and maintain and report spaces that are occupied by connected vehicles. It also uses short range communications to provide parking information to vehicles. | False |
|---|
| RSE Position Correction Support | 'RSE Position Correction Support' broadcasts differential positioning data to enable precise locations to be determined by passing vehicles, supporting Connected Vehicle applications that require highly accurate positioning. The differential positioning data may be calculated directly by a precisely located RSE that is operating as a reference station or received from an external reference station and relayed to passing vehicles. | False |
|---|
| RSE Road Closure Management | 'RSE Road Closure Management' communicates with qualified Connected Vehicles and barrier control systems to support local road closure management. It validates and requests implementation of road closure requests. During a closure, it can also support selective access to the closed area, only granting entry permission to allowed vehicles. | False |
|---|
| RSE Situation Monitoring | 'RSE Situation Monitoring' is a general functional object that supports collection of traffic, environmental, and emissions data from passing vehicles. The data is collected, filtered, and forwarded based on parameters provided by the back office. Parameters are provided to passing vehicles that are equipped to collect and send situation data to the infrastructure in snapshots. In addition, this object collects current status information from local field devices including intersection status, sensor data, and signage data, providing complete, configurable monitoring of the situation for the local transportation system in the vicinity of the RSE. | False |
|---|
| RSE Support Services | 'RSE Support Services' provides foundational functions that support data collection, management, location reference, timing, and data distribution. It coordinates with Support subsystems to maintain necessary registrations with respect to location and scope. It maintains precise location and time information to support other services. | False |
|---|
| RSE Transit User Guidance | 'RSE Transit User Guidance' uses short range communications to provide terminal or stop–specific guidance to transit user devices that assists users in finding the right stop and the right bus. Optionally, this object can collect the transit user location and planned itinerary so that tailored guidance can be provided. | False |
|---|
| RSE Traveler Information Communications | 'RSE Traveler Information Communications' includes field elements that distribute information to vehicles for in–vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the short range communications equipment that provides information to passing vehicles. | False |

| Document Number | Title | Description |
|---|
| ISO 21217 | Intelligent transport systems –– Communications access for land mobiles (CALM) –– Architecture | ISO 21217 describes the communications reference architecture of nodes called "ITS station units" designed for deployment in ITS communication networks. While it describes a number of ITS station elements, whether or not a particular element is implemented in an ITS station unit depends on the specific communication requirements of the implementation. It also describes the various communication modes for peer–to–peer communications over various networks between ITS communication nodes. These nodes may be ITS station units as described in the document or any other reachable nodes. ISO 21217 specifies the minimum set of normative requirements for a physical instantiation of the ITS station based on the principles of a bounded secured managed domain. |

| NIST FIPS PUB 140–2 | Security Requirements for Cryptographic Modules | This Federal Information Processing Standard (140–2) specifies the security requirements that will be satisfied by a cryptographic module, providing four increasing, qualitative levels intended to cover a wide range of potential applications and environments. The areas covered, related to the secure design and implementation of a cryptographic module, include specification; ports and interfaces; roles, services, and authentication; finite state model; physical security; operational environment; cryptographic key management; electromagnetic interference/electromagnetic compatibility (EMI/EMC); self–tests; design assurance; and mitigation of other attacks. |
