A method for secure, high-availability transmission of messages includes communicating a transmission of messages on a first channel secured using a message authentication code on a redundant private databus. The redundant private data bus is configured to connect a first control unit and a second control unit. The method further includes communicating a transmission of messages on a second channel without protection using the message authentication code on the redundant private databus. The messages transmit signals. Signals from the first channel are used in a first operating state, and signals from the second channel are used in a second operating state.
