Abstract

The invention relates to a data sharing method and system under the cloud computing environment. The method comprises the user data encryption storage step and the user data extraction step. The user data encryption storage step comprises the particular steps that a data processing server sets up data index keyword information for user data and generates a matched data ciphertext index and a matched data extraction token, the user data are stored in a cloud storage platform after being encrypted, the data ciphertext index and a data storage address are stored in a data extraction server, and the data extraction token is transmitted to a user. The user data extraction step comprises the particular steps that after receiving the data extraction token, the data extraction server verifies the legality of the data extraction token, extracts data from the cloud storage platform according to the data storage address, and the data are returned to the user by the data extraction server after being decrypted by the data processing server. According to the data sharing method and system, the data storage safety under the cloud computing environment is ensured, and meanwhile the problem of user data sharing is conveniently solved.

Description

technical field

[0001] The invention relates to the technical field of data information security, in particular to a safe user data sharing method and system 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 used or ...
