Original Abstract

Using modern methods to control vehicle access is becoming more common. At present, various approaches and ideas are emerging on how to ensure the access in use cases reflecting car rental services, car sharing, and fleet management, where the process of assigning car access to individual users is dynamic and yet must be secure. In this paper, we show that this challenge can be resolved by a combination of the PKI technology and an access management system. We implemented a vehicle key validation process into an embedded platform (ESP32) and measured the real-time parameters of this process to evaluate the user experience. Utilizing the SHA256-RSA cipher suite with the key length of 3072 bits, we measured the validation time of 46.6 ms. The results indicate that the user experience is not worsened by the entry delays arising from the limited computing power of embedded platforms, even when using key lengths that meet the 2020 NIST recommendations for systems to be deployed until 2030 and beyond.
