Research on CP-ABE Based Dynamic Access Control for Cloud Storage

针对在解决海量数据存储和数据共享,云存储中的数据访问控制面临的安全问题,采用密文策略的加密算法CP-ABE对云存储环境下的数据进行加密/解密,实现了CP-ABE云存储数据动态访问控制,并进行了仿真和性能分析,通过研究云存储中的数据动态访问控制,能够很好地保护用户数据的完整性,解决了传统分布式环境下访问控制的数据安全问题。实验结果表明,上述加密算法的研究在开放云存储系统数据访问控制的完整性、安全性和高效性方面具有很大的优势。

Security issues of data access control become to be the major concern in the cloud environment, especially when it comes to big data storing and information sharing. By encrypting and decrypting data with CP-ABE encryption algorithms, this study performs a simulation experiment and performance analysis on CP-ABE dynamic data access control for cloud storage. This paper finds that understanding dynamic data access control is the key to enhance data integrity and meet the security requirement for data access control in traditional distributed environments. Results show that the research of the above encryption algorithm presents great advantages in the integrity, security and efficiency of data access control in cloud open resource platforms.
