【Abstract】Vehicle-to-vehicle (V2V) video content dissemination is fundamental for many emerging services (e.g., on-road entertainment and roadside surveillance). However, many security, privacy, and trust issues hinder the large-scale promotion of this service. Malicious entities may spread incomplete and illegal content or defraud the requester to obtain rewards. Moreover, resource consumption and possible privacy leakage issues decrease the participation of many vehicle users. To address these issues, we propose a blockchain-based trust and scalable V2V video content dissemination framework to create an excellent content caching and sharing ecosystem with resistance to diverse attacks and adaptation to high mobility. Under a decentralized framework, a fair reward strategy is designed to price each video content transaction as a V2V service fee. A vehicle-group selection policy for many-to-one video content delivery is developed to minimize service fees subject to the constraints of the number of video layers, vehicle reputation, V2V connection duration, and achievable transmission rate. Smart contracts are designed to regulate transaction triggering, verification, and rewards, with a traceable punishment mechanism against malicious behaviors. We provide the proposed scheme's security analysis and simulation results, demonstrating our scheme's security, feasibility, and superiority.
