Problems solved by technology

[0004] The present invention is aimed at the existing cloud computing environment data sharing when users download their own encrypted data from the cloud storage platform to the local and then decrypt it and then pass it on to others. There are potential safety hazards, and a cloud computing environment data sharing method is provided, which establishes data index keyword information and generates matching data ciphertext indexes and data extraction tokens, while ensuring the security of cloud computing environment data storage, it is convenient effectively solve the problem of user data sharing

Embodiment Construction

[0034] The present invention will be described below in conjunction with the accompanying drawings.

[0035] The invention relates to a cloud computing environment data sharing method, which can realize user data sharing in the cloud computing environment, and its principle is as follows: figure 1 As shown, mark 1 and mark 2 are user A and user B respectively, and both user A and user B are users in the cloud computing environment, and they are also users of cloud computing services. How data is shared with user B. This method aims at the problem of safe data sharing under the cloud computing environment (or cloud storage environment), introduces the data processing server 3 to receive user A data, encrypts and stores user A data, performs encryption and decryption operations, and is responsible for generating matching For information such as data ciphertext index and data extraction token, when data processing server 3 encrypts and decrypts, it may specifically request passw...

Abstract

The present invention relates to a cloud computing environment data sharing method and system. The method includes a user data encryption storage step and a user data extraction step. The user data encryption storage step includes establishing data index keyword information for user data through a data processing server, and generating The matching data ciphertext index and data extraction token encrypt the user data and store it on the cloud storage platform, then store the data ciphertext index and data storage address to the data extraction server, and pass the data extraction token to the user; the user The data extraction step includes that the data extraction server verifies the legitimacy of the data extraction token after receiving the data extraction token, and then extracts the data from the cloud storage platform according to the data storage address, and returns the data after being decrypted by the data processing server to the user. The method and system involved in the invention conveniently solve the problem of user data sharing while ensuring the security of cloud computing environment data storage.

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 ...
