User security access structure and method oriented to data resource blocked storage

Abstract

The invention discloses a user security access structure and method for data resource blocked storage. The structure comprises a cloud server and a user, and the cloud server comprises a virtual machine manager and a plurality of virtual machines. The method comprises the steps: applying a data resource demand of a user; the virtual machine manager authenticating the identity of the user; the virtual machine manager retrieving data resources required by the user and sending retrieval result information to the user; the user receiving the retrieval result information; the user generating parameter information of the data block public key and the data block private key according to the received retrieval result information; the user transmitting the parameter information of the data block private key to the virtual machine manager; the virtual machine manager transmitting private key parameter information and a transmission command sent by a user to the virtual machine; generating a datablock private key in the virtual machine; signing and transmitting a data block in the virtual machine; receiving and authenticating the signature data block by the user; and merging the data blocksby the user. And a legal user can access resources more safely.

Description

technical field [0001] The invention belongs to the field of security services for data resource storage in cloud servers, and in particular relates to a user security access structure and method for block storage of data resources. Background technique [0002] The combination of the Internet of Things and cloud storage technology has led to the rapid growth of data resources in cloud computing. More and more sensor data are transmitted to cloud servers and provide data services to users through cloud servers. At the same time, the destruction, theft and disguise of cloud data resources by illegal users are also increasing. In this case, in the cloud server, legitimate users face more serious security threats to the use of data resources. [0003] In order to maintain the security of data resources on the cloud server side, when the sensing data is stored in the cloud server, people use block storage, that is, divide and store data resources and store them in different vi...

AI Technical Summary

Problems solved by technology

[0004] Although split storage can maintain the security of data resources in cloud servers to a certain extent, with the continuous enrichment and development of data resources, the number of users has increased sharply, and various user behaviors (such as data mining, data search, etc.) The security of data resources is affected, which greatly enhances the possibility of data resources being leaked

At the same time, the means and methods for illegal users to obtain data resources through network attacks are constantly updated, their behavior is becoming more and more secretive, and the security threat to their data resources is increasing.

In this case, the data resources stored in the cloud server cannot avoid the problems of illegal operation, theft and disguise

The existence of these problems makes legitimate users full of doubts about the data resources provided by the cloud server, and it is difficult to believe that the data resources provided by the cloud server are real and safe
