Enhanced Multi-Level Secure Over-the-Air Update System using Adaptive AUTOSAR

Vehicles are majorly controlled by software run on ECUs rather than traditional mechanical components. This software is becoming very complex, adding and offering many new features. The main challenge for manufacturers is to ensure that new updates that fix bugs and add new features are done safely and quickly in the vehicle. Over-the-air (OTA) updates are the more modern solution after going to repair garage and using a wired diagnostics tester. It takes advantage of using it in modern vehicles, especially after the release of the Adaptive AUTOSAR platform which is characterized by dynamic and scalability. Applying these great features creates some challenges and risks that must be considered such as security. In this paper, we propose a solution of a multi-level security system for over-the-air updates over the Adaptive AUTOSAR platform connected with the cloud. This system interacts with the user through the mobile phone to accept or decline the updates.
