Intermediate node-based data transmission method, system and device, and storage medium

Abstract

The embodiment of the invention provides an intermediate node-based data transmission method, system and device, and a storage medium. The data transmission method comprises the following steps: a first node sends an authorization condition, a first certificate, a data access address and a conversion value of data to an intermediate node; the first node sends a second certificate to a second node;the second node sends the second certificate and a first secret key to the intermediate node; the intermediate node verifies the authorization condition and verifies the second certificate accordingto the first certificate; in response to the second certificate passing the verification, the intermediate node saves the second certificate and sends the first key to the first node; the first node receives the first secret key and stores the first secret key in an access permission list; and the intermediate node sends the data access address and the conversion value of the data to the second node. Therefore, the data transmission process is ensured to be safe and reliable.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular, to a data transmission method, system, device, and storage medium based on an intermediate node. Background technique [0002] For computer system communication requires a large amount of data transfer. Therefore, it is extremely important to ensure the reliability of the data transmission process. Data Authorized Access is the system's method of controlling the permissions users have to read data stored in the system. The current data authorization access method is usually controlled by the data provider, and it is difficult for users to provide evidence in case of disputes. Moreover, the current data authorization access is usually bound to the data provider. When the required data comes from multiple data providers, the user needs to maintain multiple authorization authentication and data entry by himself, which is very troublesome. Contents ...
