The Research Of Data Storage Security In Cloud Computing

With the development of big data era and network storage technology, people will put more and more data on the online storage and share with others. However, due to the immaturity of technology and imperfect of systems, data security issues have been plaguing people in cloud computing and it restricts the development of cloud computing. Experts focus on how to design a good cloud storage platform and a secure data storage and sharing model how to efficient and secure storage and manage the cloud data in enterprises and organizations.Currently, the major popular cloud storage platforms are Google’s GFS and HDFS, these provide a huge help for us to handle massive data. However, these platforms still have some imperfections security mechanism. Meanwhile, one of the basic cloud storage functions is to provide data sharing. It is becoming increasingly frequent between individual users who want a more secure or more efficient data. Therefore, in order to achieve the effective data storage security objectives, this paper analysis and designs a variety of scheme and finally improves the performance of HDFS. The main contents and innovations are as follows:1. This paper studies the key technologies of cloud computing data storage security, including authentication, data encryption and other technologies and these technologies provide a theoretical scheme basis for the paper.2. This paper uses the current open source cloud platform Hadoop, designs a Hadoop-Based secure storage platform, and also the system is added to a secure resource pool ensure that the entire system resource scalability and reliability. Then the paper analyzes and evaluates the performance and integrity of the entire system, it is proved that the whole system has a certain value in real life.3. Furthermore, the paper introduced KAE encryption algorithms to ensure the security of shared data. It is compared with other similar algorithms and proved that this algorithm has some advantages.
