Hardware-Acceleration Based Privacy-Aware Authentication Scheme for Internet of Vehicles

Technological advancements have led to the devel-opment of smart cities, enabling intelligent urban management. The Internet of Vehicles (IoV) is a fundamental technology connecting smart cities and vehicles to enhance transportation safety and efficiency. This interconnected system enables wireless communication among vehicles, facilitating the exchange of crucial traffic information. However, this progress raises privacy concerns for individual users. This paper introduces a novel privacy-preserving scheme that utilizes the k-Nearest Neighbors (KNN) encryption technique with multi-multi searching property for Autonomous Vehicle (AV) authentication within the IoV era. Due to the vast amount of information needed to be processed for authentication, we have implemented our scheme using hard-ware acceleration on FPGA board. Our performance evaluation demonstrates that our system exhibits less computational burden and consumes fewer resources in comparison to other existing schemes.
