Problems solved by technology

[0005] First of all, the encryption and decryption algorithms in the prior art are complicated, and complex decryption processing is required every time the virtual machine is started, which takes a long time, making the process of exporting and importing the virtual machine image file relatively long and inefficient
In addition, the existing technology also requires a complex key generation and management system, which increases the complexity of the cloud computing platform system, and further, seriously affects the user experience

Abstract

The invention provides a virtual machine image file exporting and importing method and device. The exporting method comprises the steps of obtaining an original virtual machine image file from a cloud environment; generating a virtual machine image signature based on a first user signature and a first Hash value of the original virtual machine image file; inserting the virtual machine image signature into the target position of the original virtual machine image file to obtain a target virtual machine image file, and saving the information of the target position where the original virtual machine image signature is inserted. According to the embodiment, safety protection of the virtual machine image file in the cloud environment can be achieved, it is guaranteed that only the user and cloud environment to which the virtual machine image file belongs can use the file, and the safety of the virtual machine image file and the safety of the cloud environment are improved.

Description

technical field [0001] The present application relates to the technical field of cloud environment, and in particular to a method and device for exporting a virtual machine image file, and a method and device for importing a virtual machine image file. Background technique [0002] In a virtual data center environment, a virtual machine exists in the form of an image file, and the virtual machine image file is stored in the local storage of the host or in a dedicated storage device. The virtual machine image stores virtual machine information in the form of files, including operating system, application and data information. In a private cloud environment, once the virtual machine image file is exported and then spread or stolen outside the private cloud environment, since the image file does not have any security protection measures, the virtual machine image file can be identified and run, thereby leaking information on the virtual machine. User's private and confidential...
