Abstract
When a node in automotive CAN bus is hacked, such node should be blocked to prevent severe danger in the car. In order to do that, such node should be uniquely identified. However, there is no way to identify individual nodes in a CAN bus. In this paper, a physical layer security method is proposed where individual nodes are identified by assigning unique ID to the nodes during booting process. The proposed method was implemented in a CAN controller using Verilog HDL, and it is verified that the node ID auto-setting and internal attack defense are successfully performed.
