Systems, apparatuses, and methods to identify an electronic control unit transmitting a message on a communication bus, such as an in-vehicle network bus, are provided. ECUs transmit messages by manipulating voltage on conductive lines of the bus. Observation circuitry can observe voltage transitions associated with the transmission at a point on the in-vehicle network bus. A domain bitmap can be generated from the observed voltage transitions. ECUs can be identified and/or fingerprinted based on the domain bitmaps.
