A Testbed for Automotive Cybersecurity Applying a Cyber Range
摘要
With the rapid growth of automotive software scale and requirements of communication with external of vehicles, modern vehicle will face serious cybersecurity challenges. Currently, using testbed simulation is a major approach to automotive cybersecurity research and testing, however most of the testbeds are mainly for in-vehicle network (IVN), which cannot meet many cybersecurity research and testing of modern vehicles having complex communication scenario with outside. In this paper, we proposed an automotive cybersecurity testbed simulating the Cloud-Tube-Terminal (CTT) three-layer heterogeneous networks and the Cloud-Vehicle collaborative automotive software OTA (Over the Air) update (ASOTAU) process. Our testbed first applies a cyber range to simulate cloud network and other software experimental environment that greatly promotes simulation flexibility, and integrates an experimental electric vehicle chassis and some Electronic Control Units (ECUs) that support ASOTAU, which can meet many simulation requirements of automotive cybersecurity experiment. Finally, 6 typical use examples are given to show the comprehensive simulation ability and the wide application scenarios of our testbed, and the conveniences for experimenter to use simulated experimental environment.
