A system for enhancing efficient of vehicle to everything (V2X) stream communication includes transmitting and receiving vehicles. Sensors capture information about the transmitting and receiving vehicles, and capture environmental information about an environment of the transmitting and receiving vehicles. Each vehicle has a controller that executes an application for enhancing V2X stream communication (EVSC). The EVSC obtains, from the sensors, transmitting and receiving vehicle information and environmental information. The EVSC actively and continuously engages a sparse signing approach (SSA) and a chained packet approach (CPA) portion of the EVSC to monitor bandwidth utilization and computational resource utilization for the transmitting and receiving vehicle information and environmental information, and to actively and continuously reduce bandwidth and computational resource utilization from a first level to a second level less than the first level while ensuring security of V2X communications.

In some embodiments, the receiving nodes in a network receive data based on a security peripheral's response to a transmit nodes requests for a MAC. The receiving nodes use this knowledge to avoid being spoofed.
