Abstract

The disclosure relates to a data sharing method and device. The data sharing method includes: obtaining a primary key and a secondary key of a shared device; wherein, the primary key is used to encrypt the secondary key, and the secondary key is used to encrypt the shared Encrypt data; encrypt the secondary key according to the primary key to generate a shared encryption key; encrypt the shared data according to the secondary key to generate a shared encrypted file; The shared encryption key and the shared encrypted file perform a sharing operation to the shared device, the shared encrypted key is used to decrypt the shared encrypted file, thereby reducing the probability of the shared data being cracked or hijacked during the sharing process, Improve the security of data sharing and improve user experience.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data sharing method and device. Background technique [0002] When a user uses a terminal device to store data, he usually uses a cloud server to back up the data. Generally speaking, the cloud server provider encrypts and stores the data backed up on the cloud server. In related technologies, there are several methods for encrypting and storing the data backed up on the cloud server as follows. [0003] Data is stored in clear text on the terminal device and encrypted on the cloud server. End devices obtain data through access rights. The terminal device and the cloud server use plain text when synchronizing data, and the cloud server performs encryption and decryption processing when reading and writing data. In this case, the data processing is completed on the cloud server, and the terminal device does not need to manage the encryption scheme and ...
