> I wish that vehicular systems all had air-gap level separation of messages From what I'm reading, ARINC 429 is as air-gapped as you can get. It is a one-way serial protocol (separate wires for transmit and receive). Only the wires that need to be connected are. Messages go from->to where they need to be. Unless by air gapped you literally mean "don't connect anything together" at which point you no longer have a functioning vehicle. |
