【摘要】：随着信息技术的发展和全球数据量的快速增长,云存储已经逐渐发展成为新一代的存储方式。但是用户使用云存储时在个人数据隐私方而仍有所担忧,一定程上影响了云存储的普及和推广。本文在调研了云存储的发展现状和云存储环境下用户隐私保护问题后,利用HDFS(?)勺稳定性和现有的对称加解密技术及消息摘要技术,站在云存储使用者的立场上,针对企业用户设计了一个基于HDFS的云存储接入网系统,使得企业用户能通过部署自己的接入网系统确保自己数据的隐私安全。本文给出了该系统的设计目标和原理、总体结构、层次结构、模块结构和功能设计等,并实现了该系统的用户管理、文件管理和日志管理等主要功能。本文有效地整合了J2EE企业编程框架和HDFS,并把云存储API接口集成到了系统中,系统还采用了当前主流的对称加解密算法和消息摘要算法对文件数据进行保密性和完整性处理。最后在现有的环境下进行了接入网系统的用户访问控制、文件访问控制和文件透明加解密等功能的测试,并尝试进行了文件上传下载速度和多用户操作并发压力测试。最终结果表明,接入网系统的设计目标基本完成,能够有效地保护用户的数据隐私。使企业用户能够方便的管理和放心地使用云存储服务,从使用者的角度解决了云存储的用户隐私保护问题。
[Abstract]:With the development of information technology and the rapid growth of global data, cloud storage has gradually developed into a new generation of storage methods. However, users still worry about the privacy of personal data when using cloud storage, which affects the popularization and promotion of cloud storage. After investigating the current situation of cloud storage and the protection of user privacy in cloud storage environment, this paper makes use of HDFS (?) On the basis of cloud storage user's standpoint, a cloud storage access network system based on HDFS is designed for enterprise users, such as stability, symmetric encryption and decryption technology and message digest technology. Enterprise users can deploy their own access network system to ensure the privacy of their data security. In this paper, the design goal and principle, the overall structure, the hierarchical structure, the module structure and the function design of the system are given, and the main functions of the system, such as user management, file management and log management, are realized. In this paper, J2EE enterprise programming framework and HDFS are effectively integrated, and cloud storage API interface is integrated into the system. The system also adopts the current mainstream symmetric encryption and decryption algorithm and message digest algorithm to deal with the confidentiality and integrity of file data. Finally, the functions of user access control, file access control and file transparent encryption and decryption are tested under the existing environment, and the speed of file upload and download and the concurrent stress test of multi-user operation are also tried. The final results show that the design goal of the access network system is basically completed and the user's data privacy can be effectively protected. So that enterprise users can easily manage and use cloud storage services easily, and solve the privacy protection problem of cloud storage users from the perspective of users.
