Problems solved by technology

This ensures the confidentiality of virtual machine migration to a certain extent and prevents information leakage during migration, but Xen does not implement any means of authentication and integrity protection
[0006] Of course, there are also literatures that propose a virtual machine migration model that comprehensively meets the security requirements of various aspects, but the entire migration process becomes very complicated and cumbersome, without considering the cost overhead, and the technology integration involved may not be successfully implemented and applied at present.

Embodiment Construction

[0090] The method of the present invention will be further described below with examples.

[0091] A method for safely migrating a virtual machine based on a clean room environment, comprising the following steps:

[0092] Step 1: The source node selects the destination node for virtual machine migration, including:

[0093] Step 1.1: Use the private key of the trusted key of the source node to encrypt the ID of the destination node to generate ciphertext;

[0094] Step 1.2: Use the public key of the trusted node manager to encrypt the ciphertext obtained in step 1.1 and the ID of the source node at the same time to generate ciphertext;

[0095] Step 1.3: The source node sends the ciphertext generated in step 1.2 to the trusted node manager, and enters step 2;

[0096] The source node is a trusted computer in a clean room environment, and it runs a trusted virtual machine, which needs to be migrated to the destination node;

[0097] The destination node is a trusted compute...

Abstract

The invention provides a clean room environment-based safe virtual machine migration method. Through the method, the credibility of physical computers is validated before the migration of a virtual machine, so that the virtual machine can be migrated onto a credible physical computer, and the confidentiality and integrity of the virtual machine data in the transmission process can be ensured. According to the method, the number of migration iterations can be decreased to a certain extent, so that the migration efficiency is improved; and the method is simple in realization process and easy to operate.

Description

technical field [0001] The invention belongs to the field of computer science and technology, in particular to a safe migration method of a virtual machine based on a clean room environment. Background technique [0002] In recent years, cloud computing technology is one of the most popular technologies in the computer field, and is considered to be an important trend in the development of computing technology in the future. In order to better organize and maintain the huge physical facility resources of the cloud computing data center, the cloud computing system introduces virtualization technology to realize the dynamic division of physical resources, so as to improve the resource utilization of the system and reduce the difficulty of management. An important application of virtualization technology is the dynamic migration of virtual machines. When the virtual machine dynamic migration can ensure the running of virtual machines, it can realize the migration of virtual mac...
