Abstract
Preventing spoofing in an automotive network includes monitoring, by electronic control unit, data packets on a bus in the automotive network. Upon determining, in response to the monitoring, that a data packet is from a source other than the electronic control unit, the preventing spoofing in the automotive network includes generating and transmitting a diagnostic message to at least one module in the automotive network over the bus, the diagnostic message instructing the at least one module to take no action on the data packet.
