A Model of Multi-Domain Clustering for Local Network in Modern Vehicles

Abstract

The paper reviews prospects of using domain architecture as a basis for implementing the car network security mechanism, based on the ECU authentication. It contains an analysis of the existing methods of domain formation and proposes a method for a comprehensive assessment of the security classes of car’s components, taking into account, in addition to the functional purpose of the ECU, a list of its interfaces, interaction with other ECUs, the difference between integrity levels of slave devices. Also it proffers a network clustering approach based on combining elements of one security class into a domain.
