LIGHTWEIGHT ELECTRONIC CONTROL UNIT FINGERPRINTING - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18215924 Titled 'LIGHTWEIGHT ELECTRONIC CONTROL UNIT FINGERPRINTING'
Simplified Explanation
This abstract describes systems, devices, and methods that can be used to identify an electronic control unit (ECU) that is transmitting a message on a communication bus, such as a network bus in a vehicle. ECUs transmit messages by manipulating the voltage on the conductive lines of the bus. The system includes observation circuitry that can monitor the voltage signals associated with the transmission at a specific point on the network bus. By analyzing the densities of these voltage signals, a distribution can be generated. This distribution can then be used to identify and/or create a unique fingerprint for each ECU based on its voltage signal patterns.
Original Abstract Submitted
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 signals associated with the transmission at a point on the in-vehicle network bus. A distribution can be generated from densities of the voltage signals. ECUs can be identified and/or fingerprinted based on the distributions.
