The Research and Prospect of Secure Data Access Control in Cloud Storage Environment

摘要

With the rapid development of cloud computing, users are becoming to move their data to the cloud server to avoid troublesome data management at local machines and enjoy convenient service, which might cause security and privacy protection issues of users' data. To protect data security and user privacy, access control is an effective method. Generally, access control could be realized by cryptographic methods, with which users are able to access data in cloud only when they possess a certain corresponding set of credentials or attributes. In this paper, we mainly discuss the cryptography-based secure data access control for cloud storage, as well as the future prospect. Firstly, we introduce the research background of data access control. Then we study the currently existing ABE-Based schemes of data access control which are state of the art, and make some comparisons of these schemes in detail. Finally, we list some unsolved issues of these existing access control schemes for cloud storage to provide some future development direction about the further improvement.
