摘要:

以典型的云存储体系结构为研究对象,从数据拥有者、云服务器、授权机构、用户以及用户撤销机制5个方面对云存储系统的隐私保护机制进行了研究,通过分析比较发现,云存储系统中的隐私保护问题主要可以分为系统参与者的身份隐私问题、敏感属性信息泄露问题、云存储系统敏感内容信息泄露问题。针对上述问题,研究了当前基于属性加密的云存储系统隐私保护机制,并讨论了其中存在的不足、可能的解决方案以及未来可能的研究方向。

Abstract:

The typical cloud storage architecture was presented as research objects and the privacy preserving mechanism of attribute-based encryption cloud storage including following aspects-data owner,cloud servers,au-thorized agency,data user and revocation of user was researched.By analyzing and comparing,it was discovered that the privacy preserving problems of cloud storage could be divided into privacy issues of users' identity,sensitive attribute information disclosure and leakage of privacy content in the system.Aiming at the above problems,the current privacy preserving mechanism of attribute-based encryption cloud storage was studied and shortages of the present schemes,possible solutions and the study trend in the future were discussed.

Key words: cloud storage, privacy preserving, attribute-based encryption, access structures, revocation mechanism
