9. A protection apparatus for preventing transmission of unapproved communications from a device onboard a vehicle, the protection apparatus comprising a digital logic architecture, including:
-
a transmit data signal input port, configured to receive a data communication for further processing; and a transmit enable signal input port, configured to receive an activation signal transmitted by a network controller; wherein the protection apparatus is configured to; receive the activation signal and the data communication, transmitted by the network controller; determine whether the data communication is approved; and prevent further transmission of the activation signal to block receipt of the data communication at a network transceiver, when the data communication is not approved. - View Dependent Claims (10, 11, 12, 13, 14, 15)
