Embodiment Construction

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0033] The solutions of the embodiments of the present invention are mainly: using the virtualization redirection technology, taking the sandbox technology as an example, all encrypted file access, viewing and editing are deployed in the sandbox. The sandbox redirects and encrypts all files in the sandbox, and all files or text in the sandbox cannot be copied and pasted. When users need to share encrypted files, they need to export the encrypted files to the sandbox, and encrypt the documents when exporting; when users need to view and edit encrypted files, they need to import them into th...

Abstract

The invention relates to a method, a device and a server for encrypted file management. The method includes the steps: when encrypted files are led out from a designated position for redirected storage of the encrypted files, sending secret key requests to a server side, receiving secret keys sent by the server side and leading out the encrypted files after encrypting; and when the encrypted files are led into the designated position, sending secret key requests to the server side, receiving secret keys sent by the server side and leading in the encrypted files after decrypting. The encrypted files are redirected and stored in the designated position, and users are supposed to check and compile the encrypted files at the designated position. Special encryption and decryption algorithms are used for encrypting and decrypting files, so that a third party cannot check specific contents of the encrypted files even acquiring the encrypted files, and safety and sharing of confidential files are guaranteed.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device and server for managing encrypted files. Background technique [0002] As enterprises attach importance to the confidentiality of internal data, some confidential file management solutions for internal data have also begun to be applied. One of them is a physical segregation scheme, whereby all confidential files are restricted to the internal network, which is not connected to the Internet. In addition, it also includes the technology of sandbox isolation, that is, the use of sandbox to isolate the Internet environment and the office environment. The above isolation scheme brings security to enterprise data, but also brings inconvenience to the sharing of confidential files. In addition, since individuals within an organization or branches of an organization often need to share some confidential documents, auditing and secure sharing of confidential document...
