Data safety storage method and system under cloud computing environment

Abstract

The invention relates to a data safety storage method and system under the cloud computing environment. The method comprises the steps that a secret key mixed server is interacted with a user to obtain an encryption and decryption token, the secrete key mixed technology is adopted in the secret key mixed server to enable the encryption and decryption token to be mixed with an initial secrete key provided by a secrete key management server so as to obtain a data encryption and decryption secrete key, encryption and decryption are carried out on data by an encryption and decryption server according to the encryption and decryption secrete key, and after being encrypted, the data are stored in a cloud storage platform. According to the data safety storage method and system, the secret key mixed server is introduced, the secrete key mixed technology is applied, the data leakage problem caused by conspiring of a secrete key management party and a data storage party can be solved, and the data safety storage under the cloud computing environment is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of data information security, in particular to a method and system for securely storing user data in a cloud computing environment. Background technique [0002] Cloud computing is a delivery model of IT resources and services, which can achieve anytime, anywhere, convenient and on-demand access to the required resources (such as network, server, storage, applications, services, etc.), these resources can be rapidly provisioned and released with minimal administrative cost or service provider intervention. With the development of cloud computing technology and the continuous progress of cloud computing business, cloud computing will play an increasingly important role in the IT field. [0003] In the cloud computing environment, the user's data is stored on the cloud storage platform, which is physically out of the user's control. Users are most worried about whether their data is protected, whether it is ...
