Abstract
Systems, apparatuses, and methods to establish ground truth for an intrusion detection system using machine learning models to identify an electronic control unit transmitting a message on a communication bus, such as an in-vehicle network bus, are provided. Voltage signatures for overlapping message identification (MID) numbers are collapsed and trained on a single ECU label.
