Embodiment Construction

[0043] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0044] Below at first explain and illustrate with regard to the technical terms of the present invention:

[0045] User: refers to the user of the cloud service, who needs to store local files in the cloud, and has the right to verify the integrity of outsourced files; this system involves multiple users simultaneously verifying data integrity;

[0046] Cloud storage server: It is mainly responsible for storing user's data and signature, which is semi-trusted (honest but curious). In addition, corresponding evidence must be provided for the challenge of data ...

Abstract

The invention discloses a cloud-storage batch auditing method based on MapReduce, and the method comprises the steps that a user carries out the initialization of a local file; a request is sent to a TPA when the user wants to verify the integrity of packaged data; the TPA challenges a cloud storage server at each time when the request is received, and the cloud storage server returns an evidence corresponding to the file verification; the TPA verifies the data integrity after receiving the evidence; the TPA gathers the received verification evidences in each time period, and carries out one-time unified verification of data. The method can greatly improve the efficiency of batch auditing under the condition of batch auditing failures, solves a problem that a centralized auditing system is poor in adaptability, and reflects the availability of a distributed-type auditing system.

Description

technical field [0001] The invention belongs to the technical field of cloud storage and data integrity verification, and relates to a cloud storage batch audit method, in particular to a cloud storage batch audit method based on MapReduce. Background technique [0002] Cloud computing is the next generation of IT enterprise architecture, but the security problems of cloud computing hinder its large-scale application. One of the main challenges is to remotely and publicly perform integrity checks on user data on untrusted cloud storage servers. However, due to the limited resources, expertise and computing power of users, it is necessary to introduce a third-party audit to perform data integrity checks on behalf of users. However, if the third-party audit operation is inefficient, the feedback speed of the data integrity required by the user is slow, which is difficult for cloud computing users to accept; in addition, if the availability of the third-party audit is poor, the...
