BiOIoV: Biometric-based Secure Data Dissemination for IoV Ecosystem

Internet of vehicles (IoV) allows vehicles to disseminate various messages to neighbouring vehicles and these messages include traffic data, location sharing, driving assistance, road safety, and accident statistics. Additionally, an insecure channel is used for the exchange of these messages, which causes several problems, such as security attacks, data distribution, dynamic topology, vehicle mobility, user privacy, high computational and transmission overhead, throughput, or authentication process when sending these messages across an IoV network with limited resources. Considering the aforementioned issues, in this paper, we propose a biometric-based secure and lightweight message dissemination scheme (i.e., BiOIoV ) for the IoV ecosystem to mitigate various security attacks. We assess BiOIoV security and privacy defenses against various security threats in formal security analysis using Scyther and ProVerif 2.03. We also presented security proofs of BiOIoV. Then, we evaluated the performance of the proposed scheme with cutting-edge approaches. Results show the efficacy of the proposed scheme compared to state-of-the-art approaches in terms of communication overhead, computation cost, and energy consumption.
