【摘要】：隨著信息技術的發(fā)展和全球數(shù)據(jù)量的快速增長,云存儲已經(jīng)逐漸發(fā)展成為新一代的存儲方式。但是用戶使用云存儲時在個人數(shù)據(jù)隱私方而仍有所擔憂,一定程上影響了云存儲的普及和推廣。 本文在調(diào)研了云存儲的發(fā)展現(xiàn)狀和云存儲環(huán)境下用戶隱私保護問題后,利用HDFS(?)勺穩(wěn)定性和現(xiàn)有的對稱加解密技術及消息摘要技術,站在云存儲使用者的立場上,針對企業(yè)用戶設計了一個基于HDFS的云存儲接入網(wǎng)系統(tǒng),使得企業(yè)用戶能通過部署自己的接入網(wǎng)系統(tǒng)確保自己數(shù)據(jù)的隱私安全。本文給出了該系統(tǒng)的設計目標和原理、總體結構、層次結構、模塊結構和功能設計等,并實現(xiàn)了該系統(tǒng)的用戶管理、文件管理和日志管理等主要功能。本文有效地整合了J2EE企業(yè)編程框架和HDFS,并把云存儲API接口集成到了系統(tǒng)中,系統(tǒng)還采用了當前主流的對稱加解密算法和消息摘要算法對文件數(shù)據(jù)進行保密性和完整性處理。最后在現(xiàn)有的環(huán)境下進行了接入網(wǎng)系統(tǒng)的用戶訪問控制、文件訪問控制和文件透明加解密等功能的測試,并嘗試進行了文件上傳下載速度和多用戶操作并發(fā)壓力測試。 最終結果表明,接入網(wǎng)系統(tǒng)的設計目標基本完成,能夠有效地保護用戶的數(shù)據(jù)隱私。使企業(yè)用戶能夠方便的管理和放心地使用云存儲服務,從使用者的角度解決了云存儲的用戶隱私保護問題。
[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.
