Abstract: An example operation includes one or more of generating a data frame for transmission via a controller area network (CAN) bus of a transport, the data frame comprising data stored in a plurality of fields, encoding at least one authentication bit into a value within a data field of the generated data frame, wherein the at least one authentication bit comprises a digital signature based on a predefined key for the at least one authentication bit, and transmitting the generated data frame with the at least one authentication bit that comprises the digital signature via the CAN bus.
