Abstract

The invention relates to the technical field of information security, and provides a data reading and uploading method and device. The method comprises the steps: receiving an encrypted ciphertext returned by a cloud platform according to data corresponding to a data reading request, and if the data level of a first data key is inconsistent with the data level of the encrypted ciphertext, converting the first data key into a second data key corresponding to the data level of the encrypted ciphertext, and decrypting the encrypted ciphertext by using the second data key to obtain data; enabling data uploading equipment to initiate the data reading request to a data reading device, enabling the users at different user levels to send the same first data key, and enabling each user to obtain the corresponding second data key through conversion according to the level difference between the first data key and the encrypted ciphertext, so the data reading process is simplified, and a plurality of users at different user levels can read the same data conveniently.

Description

technical field [0001] This application relates to the technical field of information security, and provides a method and device for reading and uploading data. Background technique [0002] With the explosive growth of data, more and more data upload devices widely use private cloud or public cloud to store encrypted data. At present, the data upload device sets the corresponding data key according to the pre-divided user level. Based on the same data, multiple ciphertexts will be generated. Corresponding keys must be assigned to users of different user levels to ensure that users can read the data normally. , which makes it inconvenient for the above users to read the same data. [0003] In view of this, the embodiment of the present application provides a new method and device for reading and uploading data. Contents of the invention [0004] The embodiment of the present application provides a method and device for reading and uploading data, which is convenient for ...
