Rethink Physical Security: Protecting Vehicles via Battery-Enabled Sensing and Control [Point of View].

Cyberization is the foundation of vehicle electrification and automation, requiring the deployment of ever-increasing on-board sensing, communication, and computing services. However, vehicle cyberization also introduces new cyber vulnerabilities. In this article, we discuss the opportunities and challenges of using the common 12/24V automotive batteries as sensors and actuators to provide vehicles with three-pronged physical security protection: driver authentication, vehicle access control, and vehicle intrusion detection.
