Framework for packet processing for secure V2V applications on resource-constrained platforms

摘要

A packet processing framework is provided for a vehicle-to-vehicle communication packet processing system. The framework includes a neighborhood vehicle tracking module for tracking neighboring vehicles relative to a host vehicle. The neighborhood vehicle tracking module assigns a priority level of neighboring vehicles relative to a host vehicle. An adaptive security processing module regulates messages streamed to the neighboring vehicle tracker module that are in accordance with the priorities set forth by the neighborhood vehicle tracking module. The adaptive security processing module selects security modes and schedules messages streamed to the neighborhood vehicle tracking module as a function of priorities set forth by the neighborhood vehicle tracking module, a communication reliability of the transmitting neighboring vehicle, and a likelihood that a message from the neighboring vehicle is genuine as determined by the adaptive security processing module. The neighborhood vehicle tracking module outputs processed kinematics and alert information to at least one vehicle-to-vehicle application.
