ABSTRACT

The Controller Area Network (CAN), the in-vehicle network, is highly vulnerable to malicious physical and cyber attacks. To ensure the safety of both users and vehicle providers, appropriate security measures are necessary. This paper proposes a novel intrusion detection system (IDS) called Spatio-Temporal Adversarial Autoencoder (ST-AAE) for in-vehicle networks. ST-AAE utilizes the spatio-temporal characteristics of CAN traffic, a new approach in the field of in-vehicle IDS. The framework detects abnormal traffic and classifies attack types. Experimental results on real-world driving data show that ST-AAE outperforms existing models with high accuracy and low false positive rates across various attack types. Its performance is due to effective spatio-temporal feature learning, enhanced generalization through adversarial learning, and integration of CAN ID and payload information. These findings suggest that ST-AAE is an effective solution for automotive network security.
