[0049] In this embodiment, aiming at the challenges and problems existing in the data integrity verification process in the agile development cloud platform, by introducing an improved multi-branch tree and rebalancing mechanism, a data integrity verification method for the agile development cloud platform is designed, which can realize The data in the agile development cloud platform is quickly and accurately verified; the execution process of the data integrity verification method for the agile development cloud platform is as follows: figure 1 shown, including the following steps:

[0050] S101, the client divides the file to be uploaded into multiple data blocks and generates an encoded character string of each data block;

[0051] Specifically, in this embodiment, the implementation process of the above S101 is: the client generates a public key and a private key used for encrypting the file to be uploaded, and divides the file F to be uploaded into m data blocks of the s...

[0074] This embodiment provides a data integrity verification system for an agile development cloud platform, such as image 3 As shown, the data integrity verification system includes the client, cloud storage service provider and third-party audit; where,

[0075] Based on the system of this embodiment, users can upload their own data to the CSP, and when necessary, perform operations such as addition, deletion, modification, and query on the data stored in the CSP, and can also retrieve the data. Since TPA generally has strong computing power, users can send some necessary information to TPA and entrust TPA to verify data integrity. CSP can provide users with data storage services at a relatively cheap price, and respond to user requests in a timely manner. When users initiate integrity verification, they can honestly calculate and return results. TPA is credible in this system, has strong computing power and storage capacity, and can replace users to initiate data integrity...

Abstract

The invention discloses a data integrity verification method and system for an agile development cloud platform. The method comprises the steps: enabling a user side to divide a to-be-uploaded file into a plurality of data blocks and generating coded character strings of the data blocks; sending the coded character string of the data block to the CSP, and judging whether the corresponding data block is a repeated data block or not by the CSP according to the coded character string of the data block; if the data blocks are repeated data blocks, retrieving storage position information of the data blocks and storing the storage position information into a corresponding storage index table; otherwise, uploading the current data block to the CSP by the user side, and storing the storage position information of the current data block into a storage index table; enabling the user side or the TPA to send a verification challenge to the CSP; enabling the CSP to verify the data integrity and send the verification evidence to the TPA; and enabling the TPA to verify the data integrity and send a verification result to the user side. According to the invention, the problem that the data integrity cannot be quickly and accurately verified in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of cloud storage security, in particular to a data integrity verification method and system for an agile development cloud platform. Background technique [0002] With the massive use of the Internet of Things and edge devices, the amount of user data is growing rapidly. At the same time, the importance of data is gradually increasing. However, the local storage capacity of most users is limited, and the cost and time consumption of deploying security measures to protect data are unbearable for users, and technically they are far less reliable than professional cloud computing service providers. Therefore, more and more enterprises and users choose cloud storage technology to store data on remote cloud platforms. [0003] The data is stored on the cloud platform, and users can operate the data through the cloud interface. This brings great convenience to users, not only reducing storage pressure and savin...
