Abstract

The invention provides a cloud storage method and a system thereof. The method comprises the steps of transmitting a secret key application by an encrypting storage terminal to a secret key managementcenter; verifying the encrypting storage terminal by the secret key management center according to the secret key application, when verification is passed, writing a main encryption key into the encrypting storage terminal; setting a cloud storage encryption area by the encrypting storage terminal, and dividing the cloud storage encryption area into at least two encryption sub-areas; generating acorresponding derived secret key for each encryption sub-area by the encrypting storage terminal according to a main encrypting secret key; when a fact that a target file is added into the target encryption sub-areas in at least two encryption sub-areas, performing encryption on the target file by the encryption storage terminal by means of the derived secret key which corresponds with the targetencryption sub-area; and synchronizing the encrypted target file to a cloud data center by the encryption storage terminal according to a preset parameter of the cloud data center. The cloud storagemethod and the system thereof can improve safety of data which are stored in the cloud data center.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a cloud storage method and system. Background technique [0002] In recent years, with the rapid development of the Internet, mobile Internet and the Internet of Things, the amount of data generated has increased sharply, a large part of which is unstructured data. The cloud data center satisfies the needs of users to a certain extent through optimized storage. data storage needs. [0003] However, in the cloud data center, the centralized storage of data leads to the sharing of hardware storage devices of each tenant, resulting in reduced security of stored data. Contents of the invention [0004] Embodiments of the present invention provide a cloud storage method and system, which can improve the security of data stored in a cloud data center. [0005] In a first aspect, an embodiment of the present invention provides a cloud storage method, including: [0006] T...
