Analysis of Performing Secure Remote Vehicle Diagnostics

Traditionally, diagnostics of vehicles is done by plugging a physical device into a diagnostics interface in the vehicle; however, over the last years OEMs are considering to perform remote diagnostics. But connecting remotely to a vehicle opens a new entrypoint for attackers. Hence, it is important to secure the remote diagnostics procedure. We first provide an analysis of the security properties for remote diagnostics; this is done by giving a short overview over possible attacks. Next, we analyze and group diagnostic services and specify whether they are possible or suitable to be performed remotely. Last, we identify relevant security properties for each of the suitable diagnostic service groups.
