Embodiment Construction

[0041]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Since the efficiency of data integrity verification in the prior art is low, in order to solve this problem, the embodiments of the present invention provide a data integrity verification method and device. The data integrity verification method and device provided by the embodiments of the present invention will be described below through specific embodiments.

[0043] see figure 1 , the embodiment of the present invention pro...

Abstract

Embodiments of the present invention provide a data integrity verification method and device, which determine a first target master node corresponding to a group of data to be verified belonging to the same data type. Among the vine nodes linked by the first target master node, the vine nodes linking the leaf nodes corresponding to the data to be verified are determined as the first target vine nodes. According to the data corresponding to all leaf nodes linked by the first target rattan node and the rattan digital signature recorded by the first target rattan node, perform signature verification on the data corresponding to all leaf nodes linked by the first target rattan node. Through verification, it is determined that the data to be verified has passed the integrity verification, otherwise, the signature verification is performed on the data to be verified according to the leaf digital signature recorded by the data to be verified and the leaf node corresponding to the data to be verified, and the verification of the data to be verified is obtained. result. The data integrity verification is performed by applying the solution provided by the embodiment of the present invention, which improves the efficiency of the data integrity verification.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data integrity verification method and device. Background technique [0002] At present, a large amount of data is stored in computers, but the computers that store the data may be subject to network attacks, so that the data stored in the computer is tampered with, especially if the confidential data is tampered with, it will cause greater losses. Therefore, when acquiring and using data from a computer, especially when confidential data is involved, it is necessary to verify whether the acquired data is the same as the data originally stored in the computer, that is, to verify the integrity of the acquired data. In the prior art, when storing data, in addition to storing each piece of data, the digital signature of each piece of data is also calculated separately, and the calculated digital signature is stored. On this basis, after obtaining the data, data integrity ...
