A vehicular secured communication system includes a plurality of electronic control units disposed at a vehicle and interconnected by a communication network of the vehicle. The vehicular secured communication system determines if data received at an interface disposed at the vehicle is valid by (i) determining correspondence of a first parameter received via the communication network from a first electronic control unit of the plurality of electronic control units with a second parameter received via the communication network from a second electronic control unit of the plurality of electronic control units, (ii) determining correspondence of the first and second parameters with a current vehicle operating parameter or driving condition or driver profile, and (iii) comparing a vehicle behavior indicated by the received data to the current vehicle operating parameter or driving condition or driver profile.

Vehicular secured communication system

A vehicular secured communication system includes a plurality of ECUs disposed at a vehicle and a receiver of the vehicle that is configured to wirelessly receive data from exterior of the vehicle. The receiver and the plurality of ECUs are interconnected by a communication network of the vehicle. A processor is operable to process data received by the receiver and communicated by the communication network. The processor filters the communicated data by utilizing a two-step filtering process including (i) receiving first and second communication messages with respective first and second parameters from respective first and second ECUs and determining correspondence of the first and second parameters with one another and determining correspondence of the first and second parameters with a behavior of a driver of the vehicle, and (ii) comparing the behavior indicated by the communicated data to a profile typical for the driver of the vehicle.

A secured communication system for a vehicle includes a communication network of the vehicle, and a processor operable to process information communicated by the communication network. An interface of the vehicle receives data from exterior of the vehicle, and the communication network communicates information from the interface to a plurality of electronic control units of the vehicle. The processor filters the communicated information to determine if the communicated information is uncorrupted. The processor filters the communicated information by utilizing a two-step filtering process including (i) examining multiple electronic control units involved with the communicated information to determine if parameters of the involved electronic control units correspond with one another and with the current operating conditions of the vehicle, and (ii) comparing the behavior indicated by the communicated information to a profile typical for the driver of the vehicle or the current operating conditions of the vehicle.
