Abstract

The invention discloses a key processing method and system for a virtual disk. The method comprises the steps of based on a corresponding relationship among user information, virtual disk information and an encrypted management key, obtaining an encrypted first management key corresponding to first user information and first disk information; according to a digital certificate, decrypting the encrypted first management key, and according to the obtained decrypted first management key, decrypting the encrypted first file key stored in a disk head to obtain a decrypted first file key; and according to the obtained decrypted first file key, decrypting the encrypted virtual disk to obtain data content in the virtual disk. Through the method provided by the invention, a user can participate in a data encryption / decryption process and data in the virtual disk is encrypted through the digital certificate, the management key and the file key, so that the data security level of the data in the virtual disk is improved.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular to a method and system for processing keys of a virtual disk. Background technique [0002] In recent years, virtualization technology has developed rapidly and been widely used. The virtualization technology divides a section of storage space for each virtual machine on the storage device of the physical machine to store the operating system and user data of the specified virtual machine. This segment of storage space can be mapped as a virtual disk, which is uniformly managed by the virtual machine monitor. [0003] Since the virtual disk stores the user's data resources, in order to ensure the security of user data, it is necessary to encrypt and store the virtual disk, and decrypt the data when the user reads the data. However, the current virtual disk management mode is relatively simple, and users generally cannot participate in the data encryption...
