Abstract

The invention provides a data encryption method. The data encryption method comprises the following steps: allocating an encryption mode to a to-be-encrypted file; calling an encryption algorithm from an encryption algorithm selection unit based on the encryption mode; encrypting the to-be-encrypted file based on the encryption algorithm to obtain an encrypted file; and storing the encrypted file. Compared with the existing single encryption mode, a variety of optional encryption modes are adopted to improve the security of the data stored in a cloud computing data center. After one encryption mode is broken, only a part of files is lost, and the files adopting other encryption modes can still be protected.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a data encryption method and device. Background technique [0002] Cloud computing data center is a new type of data center based on cloud computing architecture, loosely coupled computing, storage and network resources, fully virtualizing various IT equipment, high modularization, high automation, and high degree of green energy saving center. [0003] Because the cloud computing data center stores a large amount of data, and the user access volume of the cloud computing data center is extremely large, in order to ensure the security of the stored data, data encryption becomes extremely important. In the prior art, commonly used encryption methods include content-aware encryption and format-preserving encryption. However, only one method can be used for data encryption, and the algorithm is single. Once the algorithm is cracked, all data will face the danger of leaking. ...
