US: GTFS-Flex - Secure Wireless Internet (ITS)
Description:
This solution is used within the U.S.. It combines standards associated with US: GTFS-Flex with those for I-M: Secure Wireless Internet (ITS). The US: GTFS-Flex standards include upper-layer standards required to implement dynamic, public, transit-related communications. The I-M: Secure Wireless Internet (ITS) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.Relevant Regions:

Solution Issues Severity: 3
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| True | Medium | Not a standard | Standardization Gap | The document may be publicly available but it is not currently available as a formal standard and details may change prior to adoption as a standard. |
| False | Medium | Option not standardized | Standardization Gap | The option set includes at least one option that is not (yet) defined in a standard. |
| False | Medium | Overlap of standards | Overlap | Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow. |
| False | Medium | Regulatory Permission Needed | Standardization Gap | Deployment of this standard requires regulatory approval, which is currently subject to significant delays. |
| False | Medium | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
| False | High | Regulatory Issue | Standardization Gap | Deployment of this standard is subject to regulatory approval, which is not currently expected to be granted for deployments in the near-term. |
