This solution is used within the U.S.. It combines standards associated with US: WZDx with those for I–I: Secure Internet (ITS). The US: WZDx standards include upper–layer standards required to implement work zone information data exchanges. 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.

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.
