Embodiment Construction

[0038]The main idea of ​​the method for guaranteeing the trustworthiness of the virtual machine proposed by the present invention is to separate the virtual trusted root module in the cloud server from the virtual machine, set up a separate device, and use this device to complete the trustworthiness measurement of the virtual machine. The main content includes the communication mechanism between the root of trust device and the cloud server, and the method of virtual machine trustworthiness assurance—the establishment and transmission of the trust chain. The specific implementation will be explained according to the accompanying drawings:

[0039] 1, figure 1 Introduce the communication mechanism between the root of trust device and the cloud server

[0040] Considering the safety problem of network transmission, the present invention designs a set of safe communication protocol. The communication protocol should guarantee the confidentiality, integrity and non-repudiation o...

Abstract

The invention provides a virtual machine credibility guaranteeing method in a cloud environment and belongs to the field of information safety. The method is characterized in that a virtual credible root module is separated from each server in the cloud environment and is concentrated into a device, the device comprises a physical credible root, credible root virtualization is completed, credibility computing related work is provided for a virtual machine in the cloud environment, and main work content comprises two parts, namely establishing of the communication mechanism between the credible root device and the cloud server and the virtual machine credibility guaranteeing method. According to the method, the virtual credible root and the virtual machine are not on the same platform, virtual machine migration is needed, then the virtual machine and the virtual credible root are correlated again after virtual machine migration, and accordingly the problem of virtual machine migration is effectively solved.

Description

technical field [0001] The invention relates to a trusted guarantee method for a virtual machine in a cloud environment, which provides a safe and trusted solution for cloud platform users based on cloud computing and trusted computing technology, and belongs to the field of information security. Background technique [0002] As an emerging computing model, cloud computing has set off a new wave of industry with the advantages of pay-as-you-go, cost reduction, anytime, anywhere, energy saving and consumption reduction. In the cloud computing mode, users need to transfer their own data and applications to cloud servers or virtual machines for storage or operation. However, these data and applications may be subject to malicious theft, tampering, and threats from other users in the cloud. [0003] The continuous progress of trusted computing technology and security chip technology has put forward new ideas for solving these security problems. The basic idea of ​​trusted comp...
