US: SAE Weather Info - Secure Wireless Internet (ITS)
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Weather Info with those for I-M: Secure Wireless Internet (ITS). The US: SAE Weather Info standards include upper-layer standards required to implement V2X weather information flows. 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:
- Canada
- United States

Solution Issues Severity: 4
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| False | Low | Overlap of standards (Minor) | 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. However, as this information transfer is infrastructure-based, agencies can deploy a solution throughout their jurisdiction with minimal downside and can use gateways to connect to other technologies. |
| False | Low | Time synchronization | Performance / Applicability Gap | The standard requires a highly accurate time shared between participants. |
| 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 | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
| False | Medium | Unvetted by community | Standardization Gap | The proposed solution uses a suite of standards that is accepted within some communities, but has not necessarily been accepted for use within the context of this information triple. |
| 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. |
| True | Low | Data not defined in standard format | ITS Info Gap | The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS. |
| True | Medium | Outdated security reference | Security Gap | The standard solution includes an outdated security reference. |
