Problems solved by technology

[0004] For the integrity of cloud data, most of the current protection mechanisms rely on trusted third-party audit institutions, increasing the threat of data leakage to third parties, and the threat of collusion between cloud service providers and third-party organizations cannot be avoided

Embodiment Construction

[0050] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0051] The present invention designs a cloud environment distributed hash chain architecture. The nodes involved are functionally divided into two categories: virtual machine proxy nodes and storage nodes. When a user submits a storage task, the virtual machine proxy node is responsible for file Perform preprocessing, select the appropriate storage node to save the data, and after all the storage is completed, the virtual machine agent node will return the result to the user.

[0052] In order to apply to complex services in the cloud distributed environment and enhance the portability of the model, the present invention first runs a special container on the node to prep...

Abstract

The invention discloses a cloud environment distributed hash chain framework and a cloud data integrity verification method. According to the invention, a virtual machine of a user is expanded and then a virtual machine agent model is obtained. In this way, a whole design system is enabled to be good in flexibility, cross-platform performance and expansibility. After that, a distributed hash chainis built in combination with the cloud multi-user characteristic environment. Through the information exchange among multiple users, an action protocol consensus is achieved so as to complete the trusted integrity verification. The invention further relates to a data integrity monitoring and verification method based on the cloud environment distributed hash chain framework. The virtual machine agent technology is adopted to maintain the distributed hash chain on the basis of the cloud environment. Therefore, data can be monitored in real time, and the integrity of the data can be effectivelyguaranteed. The actual working safety and the efficiency can be improved.

Description

technical field [0001] The invention relates to a cloud environment distributed hash chain architecture and a cloud data integrity verification method, belonging to the technical field of cloud computing and information security. Background technique [0002] Cloud computing is a computing model that uses the Internet to access shared resource pools (such as computing facilities, storage devices, applications, etc.) anytime, anywhere, on-demand, and quickly, and provides users with pay-as-you-go. Cloud storage is a cloud computing system centered on data storage and management. Users can access cloud data anytime, anywhere, through any network-connected device. However, the unique centralized storage method of cloud data has resulted in the separation of user ownership and management rights, bringing potential security risks of data theft and destruction. [0003] The problem of cloud data integrity has become a research focus. On the one hand, cloud service providers may ...
