Discovering CAN Specification Using On-Board Diagnostics

초록

The work presented in this article leverages on-board diagnostics for reverse-engineering controller area network (CAN) traffic data. The analysis of these data can be utilized to improve in-vehicle network security. The article proposes a CAN reverse-engineering algorithm that can be used to discover CAN specification of a target vehicle related to significant vehicle parameters. Using the proposed method, security researchers can analyze CAN traffic of vehicles more efficiently and save time wasted by lack of information. It proposes a novel CAN reverse-engineering algorithm that autonomously analyzes CAN traffic data with onboard diagnostic (OBD-II) query responses to discover the information of CAN implementation associated with major vehicle parameters.
