大数据环境下云数据的访问控制技术研究

Research on cloud data access control technology in big data environment

传统的数据访问控制技术相对完善,基本可以达到保护数据资源不被非法访问的目的,可是随着计算机和网络技术的发展,云计算时代到来,数据的计算模式和存储模式都发生了翻天覆地的变化。有效地将数据访问控制技术应用到大数据环境下的云数据安全维护是如今云计算发展的重要项目。面对这个挑战,着重从访问控制模型、ABE密码机制和多用户访问控制等方面对大数据环境下云数据的访问控制进行研究。

The traditional data access control technology is relatively perfect,and can basically protect the data resourcesfrom illegal access. With the development of computer and network technology,and the coming of cloud computing era,the for?mation of big data environment,data′s calculation mode and storage mode have changed dramatically. How to effectively applythe data access control technology to the cloud data security maintenance in big data environment is the important project of cur?rent cloud computing development. To overcome this challenge,the cloud data access control in big data environment is studiedin the aspects of access control model,ABE password mechanism and multi?user access control.
