Summary
In this project, we have taken a multi-pronged framework to comprehensively study how to harden and secure the connected and automated vehicle (CAV) ecosystem by simultaneously considering cybersecurity threats posed to CAVs and physical and cyber transportation infrastructure that support CAV operations. We have also explored how to leverage intelligent collaborations amongCAVs and between CAVs and physical/cyber transportation infrastructures to develop solutions to defend the CAV ecosystem against both physical and cyber threats in a holistic fashion. More specifically, we have carried out major research activities along four key aspects including CAV ecosystem threat analysis and risk assessment (TARA), shared state approach against cybersecurity attacks on CAV teleoperation, robust collaborative perception under lossy networks, and infrastructure-based anomaly detection.
