论文摘要
Data sharing and privacy securing present extensive opportunities and challenges in vehicular network. This paper introduces `trust access authentication scheme’ as a mechanism to achieve real-time monitoring and promote collaborative sharing for vehicles. Blockchain, which can provide secure authentication and protected privacy, is a crucial technology. However, traditional cloud computing performs poorly in supplying low-latency and fast-response services for moving vehicles. In this situation, edge computing enabled Blockchain network appeals to be a promising method, where moving vehicles can access storage or computing resource and get authenticated from Blockchain edge nodes directly. In this paper, a hierarchical architecture is proposed consist of vehicular network layer, Blockchain edge layer and Blockchain network layer. Through a authentication mechanism adopting digital signature algorithm, it achieves trusted authentication and ensures valid verification. Moreover, a caching scheme based on many-to-many matching is proposed to minimize average delivery delay of vehicles. Simulation results prove that the proposed caching scheme has a better performance than existing schemes based on central-ized model or edge caching strategy in terms of hit ratio and average delay.
