Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In the embodiment of the present invention, for the data stored in the cloud, the cloud server encrypts this part of data from plaintext to ciphertext before storing, so that even if the data stored in the cloud is leaked, it is difficult for a third party to obtain the real data , thereby ensuring the security of cloud storage data and the information security of cloud server users.

[0020] figure 1 The implementation flow of the cloud storage data protection method provided by the embodiment of the present invention is shown, and the details are as follows:

[0021] In S101, the cloud s...

Abstract

The invention relates to the technical field of information security and provides a method for protecting cloud storage data and a cloud server. The method comprises the steps that data uploaded by a client side are received by the cloud server; the data uploaded by the client side are encrypted by the cloud server through a locally-stored key according to a preset encryption algorithm, so that encrypted data are obtained; the encrypted data are stored by the cloud server. According to the method, in terms of the cloud storage data, the data are converted into a ciphertext from a plaintext by the cloud server and stored by the cloud server, so that even though the cloud storage data are leaked, the real data are difficult to obtain for a third party, the safety of the cloud storage data is guaranteed, and therefore the information safety of a cloud server user is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a method for protecting cloud storage data and a cloud server. Background technique [0002] With the development of Internet technology, cloud storage derived from cloud computing has gradually begun to change users' data storage habits. It uses functions such as cluster applications, grid technology, or distributed file systems to integrate a large number of different types of Storage devices work together through application software to jointly provide data storage and business access functions. Compared with the traditional method of storing data locally, it can better ensure data security and save local storage. Therefore, more and more users start to use cloud storage to back up data. By registering as a cloud server user, they can obtain a certain amount of cloud storage space. After logging in to the cloud server, they can upload files on their mo...
