Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0050] A data holding verification method comprising:

[0051] Cloud server side method:

[0052] A1) receiving the data block and the data block signature sent by the cloud user side, wherein the data block is a data unit formed by splitting data;

[0053] A2) If the verification request sent by the verification side is received, the verification evidence is generated according to the data block and the data block signature corresponding to the verification request;

[0054] A3) Send the verification evidence feedback to the verification side for data holding verification;

[0055] Verification side method:

[0056] B1) Generate a verification request, and send the verification request to the...

Abstract

The invention discloses a data holding verification method and system. On the cloud server side, verification evidence is generated according to the verification request of the verification side, the data block of the data corresponding to the verification request and the data block signature, and the verification evidence is sent to the verification side for data holding verification; the integrity of data held by the cloud server can be effectively verified, and data counterfeiting based on cloud service business is avoided; the invention is not only suitable for a single-cloud user scene, but also suitable for a multi-cloud user scene.

Description

technical field [0001] The invention relates to a data holding verification method and system, belonging to the field of cloud computing services. Background technique [0002] With the application of cloud computing in the power system becoming more and more common, and the scale development of the power system smart IoT cloud platform system, the terminal data scale of the power system will show explosive growth. Virtualized data storage service is a basic service of cloud computing, which allows power users to store data in cloud servers. This virtualized data storage mode can not only realize the centralized management of each power user, but also reduce the burden of storage management of each power user. By virtualizing data storage, individual power users can focus on their business without worrying about how to manage and access large amounts of data. [0003] However, in the power cloud service scenario based on the Internet model, the network data interaction bet...
