Paradigm change of vehicle cyber security

Recently, cyber security for non-computers, such as transportation, utility, home appliance and others has become a serious social concern. Intelligent and electrificated modern vehicles have more MCU (micro controller units), more software code than ever, which comes with huge cyber risks. Especially increased connectivity between vehicles and smart-phones / portable music-players changes the paradigm of vehicle cyber security, as virus and malware in smart-phones or music-players can invade automotive electronics. In this paper, first we introduce this new risk and assess the severity of this risk by a public risk assessment tool. Then we analyze the difficulties of cyber security in automotive electronics with limited network connectivity and low computational performance. Finally we conclude it with key findings and suggestions against this new risk.
