Problems solved by technology

However, many of the data storage systems we currently use do not implement fine-grained access control. Only simple administrator account passwords and user account passwords are used to distinguish system logins. After ordinary users enter the system, they can view The data is consistent, which is seriously inconsistent with the application scenarios in our real life that require fine-grained access control

Embodiment 1

[0028] Assume that there is a group G that needs to use the system designed by the present invention to implement a shared data storage system with fine-grained access control. There is an administrator in G who has access to all shared data {data1,...,data11} and all The user's control and management rights are responsible for establishing this data storage system to share data with the user group, and at the same time responsible for updating and maintaining this system. In the process of use, they respectively use the system building module, password generation module, password distribution module, data query module and system update module in this system in chronological order. The specific process is as follows:

[0029]1. First, the administrator determines the access level of all data {data1,...,data11}, which are divided into lv1, lv2 and lv3 from high level to low level, and the attribute set information includes {general category, literature and history, science and e...

Abstract

The invention utilizes the hierarchical tree structure to design a data storage system, which includes a system establishment module, a password generation module, a password distribution module, a data query module and a system update module. The system of the invention combines the polynomial interpolation secret sharing scheme, realizes the hierarchical control access of different users to different data through the derivation, allocation and calculation of the access password, and can be effectively applied to the sharing of multiple people who have administrators and require fine-grained access control. Data storage scenarios. The whole system has a clear structure, complete functions, simple operation, high efficiency and meets the needs of real life.

Description

technical field [0001] The invention belongs to the field of data storage, and in particular relates to an efficient data storage system using a hierarchical tree structure to control access. Background technique [0002] In real life, we often encounter scenarios where a group of people share some stored data, such as a group of students sharing library resources and archives materials, or company employees sharing public computers that store company internal materials, etc. A data storage system with superior performance can greatly improve the work efficiency of this team. Usually, this data storage system is displayed to group members in the form of a folder system. The data is first divided according to attributes such as date, type, content, size, etc., and then stored in the corresponding folder for future query. In this group of people, there is generally an administrator who has dual control over data and users. He can not only add, delete, and modify data in the s...
