Abstract

The invention discloses a data access control method and a related device, and the method comprises: enabling a data demand side node to send an access request to a data storage side node so as to obtain encrypted data, and obtaining an access authorization strategy associated with the data demand side node, wherein the access authorization strategy is issued by a data owner node, and the access authority of the data demander node to the time sequence data is limited; determining a decryption key of the encrypted data based on the access authorization policy; and decrypting the encrypted data by using the decryption key to obtain the target data. The technical scheme provided by the invention can better improve the security of data access.

Description

technical field [0001] The present application relates to the field of data access control, in particular to a data access control method and a related device. Background technique [0002] In recent years, with the digitization of various businesses in all walks of life, various data will be generated during the entire business processing process and the generated data will be stored on the chain. The data generated in the process of business processing will generate a lot of confidential data or sensitive data, which will have a certain impact on the operation of the enterprise. Once the confidential data or sensitive data is attacked by illegal personnel Or artificial leakage will inevitably cause immeasurable negative impact and loss, so continue a technical solution that can solve the above technical problems. Contents of the invention [0003] The technical problem mainly solved by the present application is to provide a data access control method and a related devi...
