US: GTFS static - Secure Wireless Internet (ITS)
Description
This solution is used within the U.S.. It combines standards associated with US: GTFS static with those for I–M: Secure Wireless Internet (ITS). The US: GTFS static standards include upper–layer standards required to implement static, 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.

Readiness: High–Moderate
Readiness Description
One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
