Analysis of Security Vulnerability Levels of In-Vehicle Network Topologies Applying Graph Representations

Abstract This article investigates cybersecurity issues related to in-vehicle communication networks. In-vehicle network security is evaluated based on the protection characteristics of components and topology network. The automotive topologies are represented as undirected weighted graphs, their vulnerability estimated specific generated graph. Thirteen different vehicle models have been investigated compare levels using Dijkstra's shortest route algorithm. An important advantage proposed method that it in accordance with most relevant evaluation models. On other hand, newly introduced approach considers Secure-by-Design concept principles.
