[0005] Existing data integrity verification protocols focus on probabilistic verification after data may be illegally tampered with, and cannot promptly and accurately distinguish between normal modification and illegal tampering when data is illegally tampered with
After calculation, if you want to achieve 99% verification accuracy, when the ratio of the number of damaged data blocks to the total number of data blocks is 0.1%, assuming that the total number of data blocks is 10,000, the number of challenges should be 4,600 blocks; when the damage ratio is 1 %, the number of challenges is 460 blocks. Therefore, in the case of relatively low damage, all the integrity protocols are relatively insufficient. In addition, the introduction of a third-party audit entity will lead to the potential threat of data privacy leakage to the third party, although it can be Random masking technology is used to label data, but it will undoubtedly increase the computational overhead

Embodiment Construction
[0056] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0057] Such as figure 1 As shown, the present invention designs a distributed virtual machine agent device based on the cloud environment. In practical applications, it specifically includes a virtual machine agent for contacting the user virtual machine and the cloud service provider server. A self-verification module is set in the user virtual machine. A trusted control chip is set in the cloud service provider server, and the virtual machine agent includes a main module, an auxiliary module, and a trusted security guarantee module, wherein the main module includes an initialization module, a database module, a data integrity verification module, and a data active monitoring module. The module is used to initialize and build a proxy network for multiple user virtual machines through the preset specified address, and in...

The present invention relates to a distributed virtual machine proxy device based on a cloud environment, which uses trusted technology to expand user virtual machines and creates an environment suitable for each module in the virtual machine proxy, making the entire design system flexible, cross-platform and Scalability; and the virtual machine agent is dynamically generated and has a certain life cycle, so it is very easy to modify and expand its functions. The present invention also relates to the data integrity guarantee based on the cloud environment distributed virtual machine agent device The method, based on the cloud environment, adopts the dynamic virtual machine agent technology to monitor the data in real time, effectively guarantee the integrity of the data, and improve the safety and efficiency of actual work.
Description
technical field [0001] The invention relates to a distributed virtual machine proxy device and a data integrity guarantee method based on a cloud environment, and belongs to the technical fields of trusted computing, cloud computing, information security, and the like. Background technique [0002] The increasing popularity and development of cloud computing technology has opened the door for users to use computing resources conveniently and at low cost, and has become a new infrastructure for the development of "Internet +". However, the separation of ownership and control of cloud user data has led to many security issues, such as data privacy leakage and data integrity damage. Therefore, it is necessary for cloud users to verify the integrity of their data. Remote data integrity verification is an effective way to solve this problem. It can verify data according to pre-stored data tags and "challenge-response" protocols without downloading user data. At present, the data...
