| dc.description.abstract | Controller Area Network (CAN), designed in the early 1980s, is the most widely used in-vehicle communication protocol. The CAN protocol has various features to provide highly reliable communication between the nodes. Some of these features are the arbitration process to provide fixed priority scheduling, error confinement mechanism to eliminate faulty nodes, and message form check along with cyclic redundancy checksum to identify transmission faults. It also has differential voltage architecture on twisted two-wire, eliminating electrical and magnetic noise. Although these features make the CAN a perfect solution for the real-time cyber-physical structure of vehicles, the protocol lacks basic security measures like encryption and authentication; therefore, vehicles are vulnerable to cyber-attacks. Due to increased automation and connectivity, the attack surface rises over time. This research aims to detect CAN bus attacks by proposing WINDS, a wavelet-based intrusion detection system. The WINDS analyses the network traffic behaviour by binary classification in the time-scale domain to identify potential attack instances anomalies. As there is no standard testing methodology, a part of this research constitutes a comprehensive testing framework and generation of benchmarking dataset. Finally, WINDS is tested according to the framework and its competitiveness with state-of-the-art solutions is presented. | en_UK |
