ECU Identification using Neural Network Classification and Hyperparameter Tuning
This work addresses intrusion detection for automotive CAN networks, presenting an incremental improvement over existing fingerprint-based methods.
The paper tackled the problem of intrusion detection in Controller Area Network (CAN) protocols by using a modified Fingerprint Intrusion Detection System with neural network classification and hyperparameter tuning, achieving a 99.4% detection rate for trusted ECU traffic.
Intrusion detection for Controller Area Network (CAN) protocol requires modern methods in order to compete with other electrical architectures. Fingerprint Intrusion Detection Systems (IDS) provide a promising new approach to solve this problem. By characterizing network traffic from known ECUs, hazardous messages can be discriminated. In this article, a modified version of Fingerprint IDS is employed utilizing both step response and spectral characterization of network traffic via neural network training. With the addition of feature set reduction and hyperparameter tuning, this method accomplishes a 99.4% detection rate of trusted ECU traffic.
