Title:
METHOD AND SYSTEM FOR PROTECTING VIRTUAL MACHINE IMAGE IN CLOUD ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2021/057024
Kind Code:
A1
Abstract:
A method and system for protecting a virtual machine image in a cloud environment, the method comprising: adding a first password when creating a virtual machine image file; creating DEK plaintext and DEK ciphertext according to the first password; using the DEK plaintext to encrypt the virtual machine image file; simultaneously storing the DEK ciphertext and the encrypted virtual machine image file in a storage pool; when reading the encrypted virtual machine image file, acquiring a second password and the DEK ciphertext; determining whether the second password is the same as the first password; if yes, then a trusted platform module acquiring the DEK plaintext according to the DEK ciphertext; and using the DEK plaintext to decrypt the virtual machine image file. The system comprises a key management module and a virtual machine image module. By means of the present application, the data security level of a virtual data center may be improved, and data security is effectively improved.
