Embodiment Construction

[0057] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] In order to avoid the problem of low data security caused by the key being stored in plaintext on the client side, the present invention provides a data processing method, which can be applied to a system including a client and a server. The original key assigned to the client is decomposed into two parts, and the two parts of the key are used by the client and the server respectively. Among them, the part of the key used by the client is stored in the client in the form of ciphertext, and the client When the original key needs to be used for data encryption or decryption processing, the second data after the encryption or decryption of the data to be processed can be obtained from the server with the partial key used by the...

Abstract

The invention provides a data processing method, device and system and a computer readable storage medium, and the method comprises the steps that a server decomposes an original key associated with aclient ID, generates first key information and second key information, stores the first key information and the second key information, and the first key information subjected to the confusion processing of the client ID is sent to the client; after receiving the data processing request, the server processes the to-be-processed data according to second secret key information associated with the client ID, generates first data and sends the first data to the client; the client performs demixing processing on the first secret key information subjected to the mixing processing to generate firstsecret key information, to-be-processed data are processed according to the first secret key information, second data are generated, the first data and the second data are combined, target data are generated, and the data obtained after encryption or decryption processing is conducted on the to-be-processed data through an original secret key are the same as the target data.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a data processing method, device, system and computer-readable storage medium. Background technique [0002] Currently, in order to ensure the safe use of data, data needs to be encrypted and decrypted. [0003] The server can distribute the device key to the mobile terminal, so that the mobile terminal can use the device key to encrypt or decrypt data. [0004] However, due to the particularity of mobile terminal use scenarios and open source operating systems, keys stored in plain text on the mobile terminal side generally have security risks. In the scenario where the key is stored in the clear, it is easy to cause the key to be stolen, tampered with, etc. safe question. Contents of the invention [0005] The present invention provides a data processing method, device, system and computer-readable storage medium to solve the problem of low data security caused...
