Evaluating trustworthiness of data transmitted via unencrypted wireless mobile communications

Abstract:

Systems and methods for making local decisions regarding the trustworthiness of V2V communications are provided. According to one embodiment, a vehicle information packet is received by a vehicle connectivity subsystem of a connected car and is indicative of an attribute of a source from which the packet was received. The source purportedly represents a neighboring vehicle in proximity to the connected car. A trustworthiness value for the packet is determined based on the source and coherence of the packet with local information maintained by the connected car. The trustworthiness value is indicative of a likelihood that the source represents a neighboring vehicle in proximity to the connected car from which communications are to be trusted. An action to be taken by the vehicle connectivity subsystem is determined with respect to the source or the packet based on the trustworthiness value. The determined action taken by the vehicle connectivity subsystem.
