Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific preferred embodiments.

[0043] A cloud audit method that supports the dynamic operation of enterprise data. This method uses global audit to serve enterprise users and protect the interests of enterprise users on the basis of sampling audits, while global audits serve the cloud provider and provide for all updated and uploaded files All data blocks are audited when uploaded to the cloud, which can effectively avoid collusion attacks by enterprise users and third-party auditors. Among them, enterprise users have third-party auditors with professional audit knowledge.

[0044] The cloud audit method uses a two-way link information table and a location array to form a dynamic structure that maps to each other to efficiently support dynamic operations. First, the two-way link information table is a two-dimensional data structure used to store au...

Abstract

According to a cloud auditing method supporting the dynamic operation of the enterprise data, a mutual mapping dynamic structure is formed by utilizing a bidirectional link information table and the position array, the dynamic updating and operation of the data can be effectively realized, and the flowability and the availability of the data are achieved. The specific method comprises a file preprocessing stage and an integrity verification stage, wherein the file preprocessing stage comprises a public and private key pair generation algorithm and a file preprocessing algorithm; the integrityverification stage is divided into a challenge generation algorithm, a proof generation algorithm and a verification proof algorithm. According to the method, the problem that enterprise users and cloud service providers are not trusted with each other is solved. Meanwhile, the privacy of outsourced file data is considered, and the privacy of audited data is protected in a block-free verificationmode.

Description

Technical field [0001] The invention belongs to the technical field of big data processing, and specifically is a cloud audit method that supports dynamic operations of enterprise data. Background technique [0002] In the era of big data, although many companies have realized the significance and role of information management, because big data has the characteristics of a wide variety, complex structure, and large quantity, the storage of enterprise information is redundant and complicated, and the search is even more inefficient and inconvenient. , The storage of large amounts of data is not true, safe and effective, and consumes a lot of communication and equipment overhead. With the development of cloud computing and the construction of supporting infrastructure, cloud platforms provide users with more and more powerful storage services, and data storage in the cloud has become an inevitable trend. However, there is still a problem of mutual mistrust between enterprise user...
