The application provides a data processing method, which can be applied to an end-cloud communication system or other systems requiring protection of data privacy. The method comprises the following steps: a user end can generate a transmission path by confusing a plurality of nodes randomly selected from a large number of relay nodes, other user ends or other service ends; and the user end can perform multi-layer encryption on data according to node information on the transmission path. In this way, in the process of transmission of the multi-layer encrypted data in the transmission path, each relay node on the transmission path can only decrypt one layer of data corresponding to the relay node, and the next layer of data obtained is in an encrypted state, so that each relay node cannot determine its position in the transmission path and cannot determine the source of the first encrypted data, and a service end cannot determine the source of the encrypted data after receiving the encrypted data. In this way, the security of data transmission is improved, and the anonymity of communication is improved.

This invention provides a vehicle-to-cloud communication method, device, electronic device, and computer storage medium. In this method, the vehicle is treated as the resource owner, similar to a server-side concept. The vehicle exposes data interfaces via protocols such as HTTP / WebSocket (i.e., vehicle application services expose their external service capabilities through APIs), allowing cloud applications or in-vehicle applications to call these services via API requests. This achieves service-oriented architecture for in-vehicle services to cloud applications, i.e., end-to-end service-oriented architecture. The vehicle-to-cloud communication protocol (API request method) is simpler; cloud apps can call target services from the vehicle via API requests, offering good versatility and fully leveraging the advantages of vehicle-side service-oriented architecture. It highlights the vehicle's central role, making it a participant in the distributed system. This service-oriented design maintains consistency in cloud application development and lays the foundation for future integration of vehicles into larger systems.
