Abstract:
Throughout the history of automobiles, advancements have been made to improve the
safety and comfort of driving. One of the latest developments involves replacing the wiring
between electronic control units (ECUs) with a networking standard called a Controller Area
Network (CAN). While CAN has proven to be an effective communication protocol, it lacks
security features that could not prevent malicious activities on the network. Therefore, there
is a need for an Intrusion detection system (IDS) that can monitor CAN network traffic
and identify any suspicious behavior. This work proposes an IDS for in-vehicle network
communication that can detect both known and unknown malicious activities using deep
learning techniques. The proposed IDS is based on Generative Adversarial Networks (GANs)
which offers several novel features compared to traditional IDS techniques. The proposed
IDS GAN model is evaluated using the Real ORNL Automotive Dynamometer (ROAD)
CAN Intrusion Dataset, which contains many network traffic samples. The results shows
that the model achieves high accuracy of 99%. Also had done a comparison with different
enhanced CNN models to detect known attacks. It is evident from the above experiments
that the model based on GANs can effectively detect network attacks and has the potential
to be applied in real-world scenarios to enhance network security.
