Embodiment 2

[0049] S302. According to the pre-established screening rules, select one of the distributed cloud data centers from multiple optional distributed cloud data centers as the target node, and the screening rules are: judging whether there is a distributed cloud data center with free storage space cloud data center.

[0050] In this embodiment, the screening rules may be based on the principle of geographical proximity and the principle of maximizing available storage space, that is, the greater the remaining storage space, the greater the possibility that the corresponding distributed cloud data center will be selected. That is, the screening rule is: judging whether there is a distributed cloud data center with free storage space. The specific judgment principle can be judged by the difference between the standard storage space and the used storage space. During specific implementation, it can be sorted according to the size of free storage space, and the distributed data cent...

example

[0069] 2.1 Suppose p=3, q=11 (p, q are both prime numbers), then N=pq=33;

[0070] 2.2r=Φ(n)=(p-1)(q-1)=(3-1)(11-1)=20;

[0071] 2.3 According to gcd(e,Φ(n))=1, that is, gcd(e,20)=1, let e=3, then d=7.

[0072] At this point, the public key and private key have been determined. The public key is (N,e)=(33,3), and the secret key is (N,d)=(33,7).

[0073] S403. The selected edge data center is used as a source node, and the selected distributed data center is used as a target node, so that the encrypted data to be backed up is backed up from the source node to the target node.

[0074] Further, in this embodiment, when backing up in step S402, it also includes: the encrypted data to be backed up is divided into several data packets, and a corresponding unique characteristic value is generated according to each of the data packets, and the several Packets are stored on different destination nodes.

[0075] Optionally, in this embodiment, multiple target nodes are used as a bl...

Abstract

The invention discloses a data storage method and device, electronic equipment and a computer readable medium, and the data storage method comprises the steps: determining an edge data center with to-be-backed-up data and a distributed cloud data center capable of carrying out data backup processing, for example, judging whether a distributed cloud data center with an unoccupied storage space exists or not; The selected edge data center is used as a source node; and selecting the distributed data center as a target node to back-up the to-be-backed-up data from the source node to the target node, for example, transmitting the to-be-backed-up data from the source node to the target node through a data communication channel established by a software defined network, thereby realizing secure storage of the data.

Description

technical field [0001] The present application relates to the field of the Internet, specifically to the field of Internet technologies, and in particular to a data storage method and device thereof, electronic equipment, and a computer-readable medium. Background technique [0002] Nowadays, the popularity of big data cloud storage is getting higher and higher, and there is no doubt that the privacy of its information is also at risk of being leaked, and the resulting data security issues cannot be ignored. [0003] Data is often stored in a database in a certain form, which is convenient for users to access and operate. Nowadays, big data emerges on the basis of a wider and more open cloud platform. On the one hand, it changes people's lifestyle and perception of data. On the other hand, it also puts forward higher requirements for the security protection of sensitive private data. It is hoped that data service providers can safely store signatures and provide reliable da...
