Implementation Aspects of Car-sharing Applications

Abstract

The concept of shared vehicles is becoming increasingly popular. Currently, there are several organizations, such as Google and Apple, that offer applications for car-sharing key management and vehicle access via a mobile app. However, these platforms are often not suitable for legacy vehicles, data processing is outsourced to third parties, and technical documentation is missing. All of this limits the scalability, increases privacy issues, and reduces the trustworthiness of the system. In this paper, we provide details on the implementation of our car-sharing solution, identifying key implementation challenges, security risks, and technological limitations. We propose an optimization technique that reduces the authentication time by 81%, making the solution practical for automotive applications. The experimental results verify the performance of our application and demonstrate its reliability in facilitating secure vehicle access in just 1.5 seconds.
