Abstract

The invention discloses a virtual machine communication data encryption method and system. The method comprises the following steps: acquiring communication data of a source-end virtual machine, and allocating a corresponding key to the communication data, wherein the communication data is an IP (Internet Protocol) message of the source-end virtual machine on a network layer; performing IPSec encryption and encapsulation operations on the communication data by using an allocated key; and transmitting the communication data being subjected to IPSec encryption and encapsulation to a destination-end virtual machine through a physical network card of a Host. Through adoption of the method and the system, encryption transmission of the communication data between the source-end virtual machine and the destination-end virtual machine is realized, and the aims of enhancing isolation of communication data among different tenant virtual machines and enhancing transmission security of the communication data among the virtual machines are fulfilled.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a virtual machine communication data encryption method and system. Background technique [0002] At present, in the cloud environment, virtual machines of different tenants are only isolated through VLANs in the virtual network, but the administrator of the cloud platform can monitor the network communication data of the tenant virtual machines on the network device (such as a bridge) of the computing node; Hackers who attack and obtain the superuser authority of the computing node can also monitor the network communication data of any tenant's virtual machine on the computing node. Therefore, how to strengthen the communication data isolation and security of the virtual machine in the virtual network has become a major challenge for cloud computing applications. [0003] The invention implements IPsec encryption on the network data packets of the virtual machine based on ...
