Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] see figure 1 As shown, a method for data storage encryption and decryption of the present invention, the method includes an encryption stage and a decryption stage;

[0032] The encryption stage includes the following steps: Step S11, the application server obtains the data to be encrypted and submits it to the data encryption service;

[0033] Step S12, the data encryption service randomly obtains the encryption type to be encrypted and generates a secret key, and stores the secret key in a secret key storage medium;

[0034] Step S13, after the storage of the secret key is completed, the data encryption service forms a series of ciphertexts from the encryption type, key index information, and encrypted data, and stores the ciphertexts in the corresponding business database;

[0035] The decryption stage includes the following steps:

[0036] Step S21, the a...

Abstract

The invention provides a data storage encryption and decryption method, which comprises the following steps of: adding an algorithm type and secret key index information to a specified position of each data string to form a string of encrypted ciphertext, and if decryption is required, encrypting the encrypted ciphertext through the algorithm type and the secret key index information of the specified position; obtaining an algorithm type and secret key information which need to be decrypted so as to carry out decryption; and ensuring the security of the encrypted data.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method and device for data storage encryption and decryption. Background technique [0002] Encryption is to change the original information data with a special algorithm, so that even if unauthorized users obtain the encrypted information, they still cannot understand the content of the information because they do not know the decryption method. [0003] With the popularity of cloud services, more and more sensitive information is outsourced to the cloud, and the data stored on the cloud needs to be encrypted. However, cloud data is not under the supervision of enterprises and individual users, so in order to prevent the leakage of private information, data needs to be encrypted before uploading to the cloud or server. Most of the existing storage encryption technologies are encryption schemes for adding key storage media or performing related processing on storage devi...
