Embodiment Construction

[0085] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0086] figure 1 It is a schematic diagram of a data integrity checking system provided by an embodiment of the present invention, including: a data processing server 101, s common servers 102, k redundant servers 103, and a checking server 104;

[0087] The data processing server 101 is configured to generate an n×s order matrix M according to the data to be tested, and the matrix and store the matrix M in the s common servers 102;

[0088] The data processing server 101 is also used to obtain the pseudo-random function f and its secret key k prf , the seed corresponding to the pseudo-random function And a random s×k order Cauchy matrix A; where, where ver represen...

Abstract

The invention provides a data integrity testing system comprising a data processing server, for generating a matrix M according to data to be tested and storing the matrix in s ordinary servers, wherein the data processing server is also used for obtaining a matrix R according to a pseudorandom function f, a key kprf and seeds Sip<ver>, obtaining a matrix R<-> according to the matrix R and a generator g, obtaining a redundancy matrix S according to the matrix M, an s*k-order Cauchy matrix A and the matrix R, and storing the redundancy matrix S and the matrix R<-> in k redundant servers; the data processing server is also used for obtaining a matrix V according to the Cauchy matrix A and the generator g and transmitting the matrix V to a testing server; the testing server is used for testing the data to be tested and outputting test results. The method implements the testing for data integrity while protecting the privacy of information, and generates the redundancy matrix S and the matrix R<-> for data testing and restoration.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a data integrity checking system and method. Background technique [0002] In the field of cloud storage technology, the data security and privacy issues that users worry about are getting more and more attention, and the integrity of data is an important basic attribute of information security. [0003] In the prior art, the RSA public-private key encryption system is generally used to check the data integrity of distributed cloud storage, and when the data is divided into blocks, as long as a part of it is extracted, it can have a high rate to ensure that the whole data is intact. However, in the process of verifying data integrity, the security of private data cannot be guaranteed while entrusting third-party verification, and dynamic update and restoration of files cannot be performed. [0004] Therefore, how to provide a data integrity verification method that prevent...
