Abstract

Modern vehicles are comparable to desktop computers due to the increase in connectivity. This fact also extends to potential cyber-attacks. A solution for preventing and mitigating cyber attacks is Over-The-Air (OTA) updates. This solution has also been used for both desktops and mobile phones. The...
