Safety dynamic migration method of Xen virtual machine

Abstract

The invention discloses a safety dynamic migration method of an Xen virtual machine, which comprises the following steps: generating a key on a source physical server based on an SSL protocol by a symmetric cryptographic algorithm; generating a public key and a private key on a target physical server based on an SSL protocol by an asymmetric cryptographic algorithm, and transmitting the public key to the source physical server; encrypting the key by the public key on the source physical server, and transmitting the encrypted key to the target physical server; decrypting the encrypted key by the private key on the target physical server to obtain the key; encrypting a transfer object by the key on the source physical server, and transmitting the encrypted transfer object to the target physical server; and after the target physical server receives the encrypted transfer object, decrypting the encrypted transfer object so as to complete migration of the transfer object from the source physical server to the target physical server. The safety dynamic migration method effectively prevents a listener from stealing the transmitted data so as to ensure transmission security of the migrated data.

Description

Technical field [0001] The invention relates to a data dynamic migration method, in particular to a Xen virtual machine safe dynamic migration method. Background technique [0002] In today's computer field, the application of virtualization technology has become more and more extensive. Virtualization means that computer components operate on a virtual basis instead of on a real basis. Virtualization technology can expand the capacity of hardware and simplify the process of software reconfiguration. Multiple operating systems can be run on one platform at the same time, and applications can run in independent spaces without affecting each other, so as to significantly improve computer performance. Work efficiency. [0003] Xen is an open source virtualization product. The Xen virtualization environment is composed of Xen Hypervisor, Domain U (also divided into para-virtualization and full virtualization), and Domain 0. Xen Hypervisor is the core and foundation of Xen. For virt...

Problems solved by technology

Hackers can modify the transmitted data, insert bugs in the virtual machine, and then control the entire virtual machine. All data and behaviors of the virtual machine are completely exposed to the eyes of hackers. Hackers can collect security information or confidential information from the operating environment of the virtual machine. Release viruses, paralyze the virtual machine operating environment, and cause serious security risks
