摘要
云计算时代,数据计算方式有所转变,数据存储模式也发生了巨大的变化。传统的数据访问控制技术虽具备一定完善性,能够防止数据资源被非法访问,然而大数据环境下,需要加强对云数据安全维护的重视力度。为化解云数据所面临的访问安全性威胁,文章以大数据环境为背景,对访问控制模型、ABE密码机制、多用户访问控制三项计算机云存储数据访问控制技术展开了探讨,而后明确了数据库-ER图,分析了数据关系表设计,并从登陆安全认证、传输加密协议、访问权限控制、文件加密四个方面分析了计算机云存储数据访问控制系统的设计与实现。
In the era of cloud computing,the way of data computing has changed,and the mode of data storage has also changed greatly.Although traditional data access control technology has some perfection and can prevent data resources from being accessed illegally,in the big data environment,more attention should be paid to cloud data security maintenance.In order to solve the access security threats faced by cloud data,this paper discusses the access control model,ABE password mechanism and multi-user access control of three computer cloud storage data access control technologies against the background of big data environment,and then defines the database-ER diagram and analyzes the design of data relationship table.The design and implementation of cloud storage data access control system are analyzed from four aspects:login security authentication,transmission encryption protocol,access control and file encryption.
