【摘要】：隨著云服務(wù)體系的逐漸成熟，云計算以各種各樣的形式影響著每個行業(yè)。改變著人們的生活方式，企業(yè)的管理模式，政府的服務(wù)途徑。人們能獲取的信息由很少迅速變成了供給遠(yuǎn)遠(yuǎn)大于需求，而重要的信息也作為一種資源，有著越來越高的價值。為了構(gòu)建龐大的數(shù)據(jù)管理系統(tǒng)，，實現(xiàn)資源的高度共享，又要保證數(shù)據(jù)的隱私性，成本的低廉性，所以私有云應(yīng)運而生�，F(xiàn)在私有云系統(tǒng)已經(jīng)越來越成熟，它的功能也越來越完善，它的價值也得到了大多數(shù)個人和企業(yè)的認(rèn)可。 對于私有云系統(tǒng)中的數(shù)據(jù)處理無疑是這個系統(tǒng)的核心，對于現(xiàn)在的社會來講，如何在現(xiàn)有的硬件條件下，提高數(shù)據(jù)處理的能力，提升數(shù)據(jù)的資源利用率，增強數(shù)據(jù)的安全性，簡化數(shù)據(jù)的管理成本是具有非常現(xiàn)實的實用意義和經(jīng)濟意義。如果再將技術(shù)用在現(xiàn)在更為流行的移動端上，就更具有實際意義。 本文主要針對私有云數(shù)據(jù)處理中的關(guān)鍵技術(shù)進(jìn)行研究，首先重點介紹了三種基本技術(shù)：分布式技術(shù)，虛擬化技術(shù)，云存儲技術(shù)。絕大多數(shù)的功能得以實現(xiàn)，都要靠這三種技術(shù)。接著研究了數(shù)據(jù)的協(xié)同編輯問題，給出了基于時間節(jié)點操作轉(zhuǎn)換的協(xié)作機制，解決了如何能夠?qū)崿F(xiàn)多人在不同地域?qū)ν粩?shù)據(jù)文件進(jìn)行協(xié)同操作的問題。并對私有云中數(shù)據(jù)安全機制進(jìn)行了研究，同時也對安全模式，常用的數(shù)據(jù)隔離方法，一定的數(shù)據(jù)加密算法進(jìn)行了研究。 通過上面研究的兩種關(guān)鍵技術(shù)結(jié)合現(xiàn)在火熱的移動端設(shè)備再次進(jìn)行深入的研究，發(fā)現(xiàn)通過類似的算法可以解決移動私有云上的數(shù)據(jù)文件同步問題，并對移動端上的數(shù)據(jù)安全進(jìn)行研究，提出了對稱整數(shù)同態(tài)算法的身份驗證和基于矩陣變化的加密算法。 最后將類似的技術(shù)用于對私有云數(shù)據(jù)管理系統(tǒng)的設(shè)計與實現(xiàn)，使設(shè)計出來的私有云系統(tǒng)具備一定的云存儲，云同步的功能，同時將存儲數(shù)據(jù)分為了公共存儲數(shù)據(jù)和私人存儲數(shù)據(jù)，并對私人存儲數(shù)據(jù)進(jìn)行了一定的加密，有一定的實用價值，并提出了更科學(xué)，更健康的私有云服務(wù)模式。
[Abstract]:With the gradual maturity of cloud service system, cloud computing affects every industry in various forms. It changes the way people live and the management mode of enterprises. The way the government services. The information that people can get quickly becomes the supply is far greater than the demand, and the important information is becoming more and more valuable as a kind of resource. In order to build the huge data management system, Private cloud emerges as the times require. Now the private cloud system has become more and more mature, and its function is becoming more and more perfect. Its value has also been recognized by most individuals and businesses. The data processing in the private cloud system is undoubtedly the core of this system. For the present society, how to improve the ability of data processing, improve the utilization of data resources, and enhance the security of data under the existing hardware conditions, Simplifying the cost of data management is of great practical and economic significance. It is even more practical if the technology is applied to the more popular mobile terminal. In this paper, the key technologies of private cloud data processing are studied. Firstly, three basic technologies are introduced: distributed technology, virtualization technology, cloud storage technology. Then, the cooperative editing problem of data is studied, and the cooperative mechanism based on the operation transformation of time node is given. This paper solves the problem of how to realize the cooperative operation of the same data file in different areas, and studies the security mechanism of data in the private cloud. At the same time, it also studies the security mode and the commonly used data isolation method. A certain data encryption algorithm is studied. Through the two key technologies studied above and combined with the hot mobile devices, it is found that the problem of data file synchronization on mobile private cloud can be solved by a similar algorithm. The security of data on mobile terminal is studied, and the identity verification of symmetric integer homomorphism algorithm and the encryption algorithm based on matrix change are proposed. Finally, the similar technology is applied to the design and implementation of private cloud data management system, so that the designed private cloud system has the functions of cloud storage and cloud synchronization. At the same time, the stored data is divided into public storage data and private storage data, and the private stored data is encrypted, which has certain practical value, and puts forward a more scientific and healthy private cloud service mode.
