A blockchain‐based trusted vehicle service recommendation scheme in intelligent transport systems

Abstract

AbstractIntelligent transportation systems usually use distributed storage to improve the access efficiency of the system. However, this type of storage makes it difficult to share data in different databases and faces the problem of data silos. Meanwhile, the lack of security protection of vehicle nodes in the network suffers from the problem of low data trustworthiness. To address the above challenges, this paper proposes a road‐vehicle dynamic shareable blockchain (RV‐DSB) system architecture. The architecture effectively ensures the integrity of vehicle data by combining blockchain and digital signature algorithms. In addition, we utilize a subjective logic model to manage the trust value of vehicles and propose a trust value‐based road‐vehicle data sharing scheme to ensure the trustworthiness of the data. Finally, we demonstrate the effectiveness of the scheme through a case study.
