Abstract

This application is applicable to the field of secure communication, and specifically discloses a data processing method and device. In this method, cloud storage data is downloaded from a storage server; The target ciphertext fragment matched by the local user attribute of ; if the target ciphertext fragment only contains the first ciphertext fragment and does not contain the second ciphertext fragment in the owner data ciphertext, use the local private key to decrypt the first ciphertext fragment; Determine the target authorized user attribute information corresponding to the second ciphertext fragment according to the authorized user attribute policy, and send the second ciphertext fragment to the second terminal device corresponding to the target authorized user attribute information, so that the second terminal device decrypts the second encrypted text fragment. As a result, multiple terminal devices can assist in decrypting cloud ciphertext data, and there is no need for direct interaction between the data owner and the decrypting user, which ensures the security and privacy of user data and can meet the ciphertext sharing needs in more scenarios.

Description

technical field [0001] The present application belongs to the technical field of secure communication, and in particular, relates to a data processing method and device. Background technique [0002] With the continuous innovation of communication and network technology, the amount of information is increasing explosively, and people's demand for storage space is increasing. In recent years, the sudden emergence of the Internet has had a huge impact on the management methods of traditional industries and traditional enterprises. The proposal and development of cloud storage services and the concept of storage as a service have made cloud storage a mainstream solution for storing massive data. [0003] In the cloud storage solution, users need to store data on a third-party cloud server, and download the required data from the cloud server when needed. Users can reduce the investment in data management and equipment management, and do not need to invest a lot of hardware and ...
