Secure communication for autonomous vehicles can be increased by performing authentication steps before the nodes (e.g., vehicles, roadside equipment (RSE), base stations, etc.) are within communications range. For example, a digital certificate management system for mobile nodes, specifically for moving vehicles, can facilitate ultra fast communications between vehicles and other nodes. In some embodiments, the RSE can propagate vehicle node data (e.g., direction, speed, estimated time of arrival, etc.) to other vehicles and/or other RSEs. Consequently, this propagation of data prior to the communication between nodes can facilitate a for efficient authentication system.
