Improvement of the Resilience of a Cyber-Physical Remote Diagnostic Communication System Against Cyber Attacks. 2019-01-0112
In the past, vehicles used to be self-contained ecosystems. Access to the E/E system was only possible via the diagnostic link connector, commonly referred to as the OBD II port, in the workshop and only by authorized staff.
Today we live in an era where electricall powered vehicles operate autonomously and communicate with their environment. This communication includes V2V, V2X and remote diagnostic communication, the latter for example to perform software over the air (SOTA) firmware updates or predictive maintenance.
To improve the resilience of remote diagnostic communication between a vehicle
and external test equipment against cyberattacks, it is imperative to understand and analyze the functionality and vulnerability of each communication system component, including the wired and wireless communication channels and the diagnostic services.
This paper explains the components of a cyber-physical system (CPS) for remote diagnostic communication, analyzes their vulnerability against cyberattacks and develops measures to improve the resiliance of the entire system.
