Because the trust relationship between the vehicles running on the expressway has not been established in advance, there is a lack of trust and hidden safety hazards when the vehicles perform cooperative download services with each other, which seriously affects the development of cooperative download. In order to achieve a trusted secure cooperative download service, a trust management solution based on the SORT algorithm is proposed, and appropriate vehicles are selected for cooperation through the service trust value. An incentive mechanism and a fair trade agreement are designed to ensure the enthusiasm and fairness of the cooperative download. Blockchain is applied. Technology stores and protects the vehicle’s identity, privacy, and data. The analysis results show that the scheme can enable users to select trusted vehicles for safe cooperative download services, and promote the download efficiency of vehicle users.

Key words: Internet of vehicles, trust management, cooperative download, blockchain
