Problems solved by technology

With the development of Internet technology, the concurrency requirements for data storage are getting higher and higher, and the original centralized data storage is increasingly unable to meet the needs due to various reasons such as price and performance.
[0003] In the prior art, a common method is to perform a full backup of the original database in a different place. Once the original database is damaged, restore the original database from the full backup. The disadvantage of this method is that the entire system needs to be suspended during recovery. and recovery is slow
Another method is to use multiple servers for mirror backup. If one fails, use other servers for recovery. However, in general, the data throughput provided by a machine is limited. If you use this machine Mirroring means that the data on several machines is exactly the same. It will take a long time to repair a database with a large amount of data. If you also need to consider providing normal services at the same time, the repair time will be greatly increased

Embodiment 1

[0089] Please refer to figure 1 , a cloud platform-based data encryption security storage method of the present embodiment, comprising the following steps:

[0090] The user terminal divides the original data file F into N unit files f 1  … f N , including:

[0091] Use the erasure code or fountain code algorithm to encode the original data, and divide the original data into N data fragments, and use the hash algorithm to obtain the storage number according to the size and type of the data fragments, and generate N unit files f 1  … f N ;

[0092] The user terminal establishes a connection with N+1 servers through the cloud platform, and uses N+1 servers as key server nodes to build a key distribution system with the cloud platform and user terminals, and uses N+1 servers as storage nodes to build a key distribution system. The server storage group of above-mentioned original data file F;

[0093] The key distribution system is established based on the verifiable SM2 thr...

Embodiment 2

[0130] Please refer to figure 2 , the present embodiment provides a cloud platform-based data encryption security storage system, including:

[0131] user terminal;

[0132] cloud platform;

[0133] server module;

[0134] The user terminal executes dividing the original data file F into N unit files f 1  … f N , and establish a connection with the N+1 servers in the server module through the cloud platform, use the N+1 servers as key server nodes to build a key distribution system with the cloud platform and user terminals, and use the N+1 servers as key server nodes The storage node constructs the server storage group of the original data file F;

[0135] The key distribution system is established based on the verifiable SM2 threshold encryption scheme, generates and executes key distribution, and distributes the generated complete key to each key server node for encrypted storage;

[0136] The cloud platform provides data communication independent of the threshold cr...

Embodiment 3

[0179] This embodiment provides a storage medium, on which a computer program is stored, and when the computer program is run by a processor, the steps of the cloud platform-based data encryption secure storage method described in Embodiment 1 are executed.

[0180] The cloud platform-based data encryption security storage method, system and storage medium of the present invention reduce the oversupply of resources, can quickly recover from storage failures in parallel, can achieve an effective balance between storage and load, and reduce key leakage Unpredictable security threats, with good security and privacy protection features, ensure the security and risk resistance of data storage.

Abstract

The invention relates to the technical field of data security, and discloses a data encryption security storage method and system based on a cloud platform and a storage medium. The method comprises the following steps: segmenting original data; establishing a key distribution system and a server storage group; calculating the weight of the storage node, and storing the original data file and theunit file; carrying out data reconstruction when the main storage node or the copy storage node is abnormal; and arranging a storage system in a matching manner. According to the method, excessive supply of resources is reduced, rapid and parallel recovery from storage faults can be achieved, effective balance of storage and loads can be achieved, unpredictable security threats caused by secret key leakage are reduced, good security and privacy protection characteristics are achieved, and the security and risk resistance of data storage are guaranteed.

Description

technical field [0001] The invention relates to the field of data security technology, in particular to a method, system and storage medium for data encryption and safe storage based on a cloud platform. Background technique [0002] Nowadays, computers are widely used in various fields, and all walks of life use computers to store and process various data, and databases are the most common data storage facilities in the computer field, and are often used to store important data. However, as we all know, due to various reasons, the database may fail or even be completely damaged, resulting in data loss; therefore, when designing an important database system, it is usually considered to backup the database so that after the database loses data, The database can be restored using the backup. At the same time, with the rapid development of technologies such as informatization, big data, and the Internet, data storage is becoming more and more important in all walks of life. F...
