Cloud platform encryption system and method

Abstract

The invention provides a cloud platform encryption system and method, and the system comprises a receiving module which receives migration data uploaded by a client; a sensitivity analysis module that is used for carrying out sensitivity analysis on an uploaded file in the migration data and setting a file permission for the uploaded file according to an analysis result; an encryption module that is used for encrypting the uploaded file with the file permission to obtain an encrypted file; a gateway module that uploads the encrypted file to a third-party cloud platform where the corresponding migration address is located, and obtains the stored encrypted file from the third-party cloud platform; a determination module that is used for judging whether the uploaded file is uploaded or downloaded according to the analysis result obtained by the sensitivity analysis module and a preset transmission strategy; and an index setting module that is used for extracting at least one first keyword from the uploaded file with the file permission and setting all the first keywords corresponding to the uploaded file as encrypted indexes. The method has the beneficial effects that data transmission among different local area networks is realized, and the security of the encrypted file is improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a cloud platform encryption system and method. Background technique [0002] With the development of science and technology, the network is becoming more and more important in daily life, and users will often use network disks, cloud disks and other products to store their own data. The advantages of cloud storage are obvious, that is, it provides a convenient outsourced storage space and reduces the burden of data storage and maintenance. But at the same time, the user loses absolute control over the data, and the data stored on the third-party cloud platform has the risk of being leaked and tampered with. Therefore, although this storage method makes the life of the user more convenient, sensitive information The insecurity of the system has threatened people's personal property safety and privacy safety. [0003] The current main method of storing sensitive data on ...

AI Technical Summary

Problems solved by technology

In addition, the existing secure cloud storage system has low security, not only is the third-party cloud platform untrustworthy, but the internal environment and personnel will also become hidden dangers of data security, resulting in the risk of data leakage;

[0004] And the current data is directly uploaded to the cloud after being encrypted before being outsourced, without further confidentiality processing of the data during uploading, so that users cannot use the privacy and security of the localized network to improve the security of data uploading
