A Digital Twin-Based Safe Authentication Protocol for Vehicular Cloud Networking

Abstract

Diverse services have been made possible by the swift expansion of autonomous vehicles; nonetheless, real-time sensing, pro- cessing, and communication overheads sometimes result in an unsatisfactory passenger experience. Our proposal utilizes cloud computing technologies to facilitate information integration and computation for autonomous vehicles, as we want to tackle these issues using a revolutionary vehicular digital twin framework. To create feedback, our method updates digital data on the cloud and synchronizes it in real time with autonomous cars. Ensuring comprehensive communication security and privacy protection is necessary to enable the real-time information synchronization of autonomous automobiles and digital twins in an open communication environment. Our proposal is to create a safe structure for data interchange between autonomous vehicles and digital twins in order to allay these worries. We discuss the security analysis of the proposed scheme. Compared to current vehicular communication protocols, we show that our proposed protocol has lower computing and communication overheads and may be applied to scenarios including digital twins. Through the reduction of communication overheads, our proposed approach improves the overall passenger experience while also addressing security and privacy concerns related to data exchange between digital twins and autonomous vehicles. The advancement of autonomous vehicles and how they are incorporated into our daily lives will be greatly impacted by our study.
