US: GTFS real-time - Secure Internet (ITS)
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: GTFS real-time with those for I-I: Secure Internet (ITS). The US: GTFS real-time standards include upper-layer standards required to implement real-time, public, transit-related communications. 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: 10
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
Default | Severity | Name | Type | Description |
---|---|---|---|---|
True | Low | Not a standard (minor) | Standardization Gap | The document is publicly available and widely used but it is not currently a formal standard. |
True | Medium | Outdated security reference | Security Gap | The standard solution includes an outdated security reference. |
True | Medium | Performance not fully defined (medium) | ITS Info Gap | The performance rules are not fully defined for this information flow. |
True | Medium | Secure data access not provided | Security Gap | The solution does not define rules on how the application entity authenticates requests to accept or provide data. |
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. |
