| Functional Object | Description | User Defined |
|---|
| ITS Management Support | 'ITS Management Support' provides management of the ITS Object. This includes management of regulatory information and policies, management of application processes, management of communication system configuration and update management, communications interfaces, protocol–specific techniques to ensure interoperability such as service advertisements, communications congestion management and interference management, local device states and communications information, billing management, fault management, service level and performance monitoring. | False |
|---|
| ITS Security Support | 'ITS Security Support' provides communications and system security functions to the ITS Object, including privacy protection functions. It may include firewall, intrusion management, authentication, authorization, profile management, identity management, cryptographic key management. It may include a hardware security module and security management information base. | False |
|---|
| MCV Roadway Maintenance and Construction | 'MCV Roadway Maintenance and Construction' includes the on–board systems that support routine non–winter maintenance on a roadway system or right–of–way. Routine maintenance includes landscape maintenance, hazard removal (roadway debris, dead animals), routine maintenance activities (roadway cleaning, grass cutting), and repair and maintenance of both ITS and non–ITS equipment on the roadway (e.g., signs, traffic controllers, traffic detectors, dynamic message signs, traffic signals, etc.). | False |
|---|
| MCV Vehicle Location Tracking | 'MCV Vehicle Location Tracking' monitors vehicle location and reports the position and timestamp information to the dispatch center. | False |
|---|
| MCV Vehicle System Monitoring and Diagnostics | 'MCV Vehicle System Monitoring and Diagnostics' includes on–board sensors capable of monitoring the condition of each of the vehicle systems and diagnostics that can be used to support vehicle maintenance. The status of the vehicle and ancillary equipment and diagnostic information is provided to the vehicle operator, repair facility, and dispatch center. | False |
|---|
| Vehicle Location Determination | 'Vehicle Location Determination' receives current location of the vehicle and provides this information to vehicle applications that use the location information to provide ITS services. | False |
|---|
| Vehicle Map Management | 'Vehicle Map Management' supports map updates and makes current map and geometry data available to other applications. It manages map data on–board and provides map data to end–user applications that provide location–based services. | False |
|---|
| Vehicle Secure Area Access System | 'Vehicle Secure Area Access System' provides access to secure areas such as shipping yards, warehouses, airports, transit–only ramps, parking gates and other areas. It accepts inputs from the vehicle driver that include the necessary identity information and uses this information to generate the request to activate a barrier to gain access to the area. | False |
|---|
| Vehicle System Executive | 'Vehicle System Executive' provides the operating system kernel and executive functions that manage the software configuration and operation and support computer resource management, security, and software installation and upgrade. | False |
|---|
| Vehicle System Monitoring and Diagnostics | 'Vehicle System Monitoring and Diagnostics' includes on–board sensors and integrated self test software that monitors the condition of each of the vehicle systems and diagnostics that can be used to support vehicle maintenance. The status of the vehicle and ancillary equipment and diagnostic information is provided to the driver and service center. | 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. |
