[0020] figure 1 The distributed data storage architecture provided in an embodiment of the present invention can apply the data recovery method or the data storage method of the present invention.

[0021] See figure 1 , the distributed data storage architecture 100 includes terminal devices 101, 102, 103, a network 104 and servers 105, 106, 107, and the network is used to provide communication between the terminal devices 101, 102, 103 and the servers 105, 106, 107 link. The network 104 may include software, hardware or a combination of both for implementing network connections. Exemplarily, when the network 104 is software, the network 104 can be a routing management program, a distributed storage management program, etc.; when the network 104 is hardware, the network 104 can be a router, a gateway, a switch, a network cable , data lines and other media. Of course, the network 104 may also be a combination of software and hardware in the above examples.

Abstract

The invention is applicable to the technical field of electric digital data processing, and provides a method and a device for storing and recovering target data, and a data storage node. The target data recovery method is executed by a distributed data storage server, and the data recovery method comprises the following steps: receiving a request for recovering target data; in response to the request, determining a first group of split data and a second group of split data stored in different data storage servers in a combined manner after the target data is split; according to the first group of split data and the second group of split data, respectively and correspondingly calculating to obtain first encrypted data and second encrypted data; and returning the first encrypted data and the second encrypted data, and indicating terminal equipment initiating the request to decrypt target data according to the first encrypted data and the second encrypted data. The method and the devicehave the effect of ensuring the safe storage of the data under the condition of not consuming longer calculation time.

Description

technical field [0001] The invention belongs to the technical field of electrical digital data processing, and specifically relates to the technology of safe transmission and safe storage of data, in particular to a method, device and data storage node for storing and restoring target data. Background technique [0002] With the rapid development of mobile network communication technology, users have more and more applications on mobile terminal devices. At the same time, the security of user data is becoming more and more important. In the prior art, transmission encryption and key-based encryption are mainly used for processing data security. Although these existing technologies have the effect of keeping secrets, the complex key algorithm needs to consume a long calculation time at the same time. Contents of the invention [0003] In view of the above problems, embodiments of the present invention provide a method, device, and data storage node for target data storage ...
