Data encryption method, user terminal, server and system

Abstract

The embodiment of the invention discloses a data encryption method, a user terminal, a server and a system, and aims to enhance the security of data storage. The method is applied to a virtual desktopinfrastructure (VDI); the VDI comprises a user terminal and a server; and a virtual machine runs on the server. The method in the embodiment of the invention comprises the following steps that: the server receives a login request of the user terminal; the server verifies the login request, and launches the virtual machine; and the virtual machine of the server acquires a key from the user terminal, and encrypts or decrypts a data file which is mounted on the virtual machine. Through adoption of the data encryption method, the user terminal, the server and the system, encryption and decryptionof a virtual desktop personal disk can be controlled through a key on the terminal, and the key used for encrypting and decrypting the data file does not exist in the server, so that an administratorcan be prevented from letting out a secret by taking away a disk storing data and keys, and the security of data storage is enhanced.

Description

technical field [0001] The present invention relates to the computer field, in particular to a data encryption method, user terminal, server and system. Background technique [0002] Virtual Desktop Infrastructure (VDI) is an enterprise-level technology that realizes remote dynamic access of desktop systems and unified hosting of data centers. It does not configure a desktop PC running Windows for each user, but runs several Windows virtual machines on the server in the data center, and each user connects to their virtual machines in a one-to-one manner, and the user's Desktops are virtualized, and users access their desktops as if they were accessing traditional locally installed desktops. [0003] With the development of servers and networks, the application of desktop virtualization technology is becoming more and more extensive. However, in the process of popularization, virtualization technology also brings some new problems. One of the problems is the risk of leakage...

AI Technical Summary

Problems solved by technology

One of the problems is the risk of leakage caused by centralized storage of user data on the server. Although there are some encryption schemes that can store user data encrypted on the server, users generally have some doubts. First, although the data is encrypted, However, the user has no perception and cannot determine whether the data is really encrypted. Second, even if the data is really encrypted, the secret key is still stored in the server disk. There is a risk of the administrator obtaining the user's confidential data, which will reduce some Acceptance of virtual desktops by users, especially those with confidential data
