The Design And Research Of Cloud Storage Data Access Control Technology

In 1980 s, the computer ushered in the first industrial revolution, after the arrival of the Internet set off a wave of the second revolution in the computer industry. However, in recent years, the emergence of cloud computing indicates that the third industrial revolution of the computer will come. Cloud computing was first proposed by the American scientist John Mc Carthy’s, he in 1960 proposed computer system, which is used can also allowed hundreds of thousands of users use the system to replace the computer at the time of the batch processing technology. But because of the technical limitations, John Mc Carthy proposed the time-sharing system is a concept that failed to achieve. Until the 21 st century, Google CEO Eric Schmidt proposed cloud computing can first use user at anytime, anywhere via mobile phones, computers and other terminal devices and cloud communication, the calculation becomes available everywhere at the same time, it also has powerful functions and performance. With the development of technology and the concept of Eric Schmidt is proposed, the cloud at your fingertips. Increase of Blue Cloud Amazon system Elastic Cloud, Computer IBM, the user also indicates that the cloud computing has gradually come into people’s life.Cloud storage is a concept derived from the cloud computing, and it is also an important part of cloud computing. The global informationization development process more and more quickly, all over the world every day the data produced immeasurable. Data is the basis of the development of the information age, is becoming more and more important invisible assets, and cloud storage can be achieved for the massive data collection, management and protection etc.. Cloud storage allows users to realize the sharing and interaction of resources in different time and space, and through the application of access control, encryption, information encryption and data isolation technology to ensure high data security. The specific work is as follows:(1) first of all because the user can get the desired system whenever and wherever possible the cloud storage service, so the DBAS structure of the system is the B/S structure. Secondly, the system is divided into three layers, respectively, page interaction layer, business logic processing and access layer, data persistence layer. Interface layer is mainly responsible for the visualization of the system and complete the interaction with the user system; business logic processing and access layer is mainly responsible for the business logic of the application data processing, is the core part of the architecture of cloud storage system; data persistence layer is mainly responsible for the safe storage and management system data.(2) functional modules of cloud storage data access control system is mainly divided into: access control, authentication server, local file encryption, encryption and data communication for disaster prevention.(3) the system testing phase, the completion of the system function and performance test. First, the realization of the function module of the system basically reached the expected goal; secondly, the server in the continuous long time uninterrupted work, page response and data transmission are very good.
