US: SAE Lane-Level Mapping - Secure Internet (ITS)
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Lane-Level Mapping with those for I-I: Secure Internet (ITS). The US: SAE Lane-Level Mapping standards include upper-layer standards required to implement lane-level and road furniture mapping information flows. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.Relevant Regions:
- Canada
- United States
Comm Profile: I-I: Secure Internet (ITS)
Comm Class: WAN - Wide Area Network

Solution Issues Severity: 7
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| 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 | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
| 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| True | Medium | Outdated security reference | Security Gap | The standard solution includes an outdated security reference. |
| True | Medium | Still under development | Standardization Gap | A draft of the standard has been developed by the working group, but it was still under development at the time this analysis was performed. |
