成果介绍

本发明属于云存储服务技术领域，提供了一种面向云存储服务平台的访问控制系统及其访问控制方法。该方法及系统中，授权中心和数据属主是基于权重属性加密机制，将需上传的用户数据加密后存储到云存储服务平台上的，因而可对云存储服务平台上的共享数据实现有效的隐私保护，提高了云存储服务的安全性。同时，由于将用户的属性与权重相结合，实现了用户属性的分级管理，使得相同属性不同级别的用户具有不同的访问权限。另外，由授权中心和数据属主分别产生部分密文，通过授权中心密文控制用户访问权限，通过数据属主密文制定访问控制策略，当用户的属性发生变化时，只需授权中心更新自己部分的密文，即可实现对用户访问权限的实时撤销。
