Abstract

The invention discloses an encryption method, a decryption method, an encryption device and a decryption device of a virtual disk and a cloud server. The encryption method comprises the steps that the cloud server acquires a first symmetric key and a second symmetric key of a VM (virtual machine) and a Ukey (user key) certificate of a Ukey accessed to the VM; the cloud server acquires a second ciphertext key by encrypting the second symmetric key through the Ukey certificate and acquires a first ciphertext key by encrypting the first symmetric key through the second symmetric key; the cloud server sends the first ciphertext key to an encryption service management server; and the cloud server encrypts the virtual disk of the VM through the first symmetric key to obtain an encrypted virtual disk. Encryption of the virtual disk of the VM is realized by interaction among the cloud server, the encryption service management server and the Ukey; and as different keys are separately managed by the cloud server, the encryption service management server and the Ukey, the encryption performance and encryption safety are improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a virtual disk encryption method, decryption method, device and cloud server. Background technique [0002] Cloud computing (Cloud Computing) is a technology that provides dynamic and easily expandable virtualized resources through the Internet. Through cloud computing, you can easily access the network, and by configuring a large number of storage devices, you can realize the storage and management of massive data. A virtual machine (Virtual Machine, VM) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Usually, multiple VMs can be simulated on a physical computer, that is, a section of storage space is allocated for each VM on the storage device of the physical computer for storing operating system and user data, and the storage space can be mapped as a virtual vir...
