【摘要】:隨著信息技術(shù)的發(fā)展和網(wǎng)絡(luò)存儲技術(shù)的完善,出現(xiàn)了一種新的存儲技術(shù)—云存儲技術(shù)。云存儲以其隨時隨地訪問的便捷性,按需使用的靈活性,極低的管理成本吸引著越來越多的人使用。公有云的數(shù)據(jù)絕大多數(shù)都是由專門負(fù)責(zé)提供云服務(wù)的服務(wù)商存儲和管理。目前,部分企業(yè)考慮到數(shù)據(jù)的安全性,已在企業(yè)內(nèi)部提供了私有云服務(wù)來滿足自身存儲需求和降低企業(yè)維護(hù)開銷。然而,作為個體的家庭用戶同樣需要將自己的私有數(shù)據(jù)進(jìn)行保存或者與家人分享,針對家庭用戶的私有云系統(tǒng)便有其存在的價值。 根據(jù)家庭用戶所具有的特點,系統(tǒng)應(yīng)該建立在嵌入式設(shè)備上,而且需要設(shè)計一種安全的私有云系統(tǒng)以保證個人數(shù)據(jù)的安全性和可靠性。整個系統(tǒng)由兩部分組成,一個是服務(wù)器,主要是一個由vsftpd作為基礎(chǔ)的FTP文件服務(wù)器,通過對vsftpd的配置,可以有效限制用戶的權(quán)限以及活動的主目錄,從而讓用戶的操作限定在適當(dāng)?shù)姆秶,這樣就保證了整個服務(wù)器的安全性和可靠性。另一個是客戶端,鑒于目前占市場份額較多的手持終端操作系統(tǒng)是Android,通過對Android客戶端的設(shè)計,實現(xiàn)了三個核心模塊,包括登錄模塊、下載文件模塊、上傳文件模塊。通過客戶端家庭用戶能方便的上傳文件到私有云服務(wù)器上,下載私有云服務(wù)器上的文件到手持終端。 最終,,整個系統(tǒng)通過在虛擬機(jī)上部署vsftpd服務(wù)器,通過配置文件限制用戶的權(quán)限和主目錄,并在手持終端安裝客戶端,能夠?qū)崿F(xiàn)文件安全和可靠地上傳和下載。
[Abstract]:With the development of information technology and the improvement of network storage technology, there is a new storage technology - cloud storage technology. Cloud storage is easy to access at anytime and anywhere, the flexibility to use, and very low management costs attract more and more people to use. The vast majority of the data of the public cloud are specially responsible for providing cloud clothes. Service providers store and manage. At present, some enterprises, taking into account the security of data, have provided private cloud services within the enterprise to meet their own storage needs and reduce enterprise maintenance costs. However, as individual home users, it is also necessary to save or share their private data with their family, for family users. The private cloud system has its value.
According to the characteristics of home users, the system should be built on embedded devices, and a secure private cloud system should be designed to ensure the security and reliability of personal data. The whole system is composed of two parts, one is a server, mainly a FTP file server based on vsftpd, through the vsftpd Configuration, can effectively limit the user's rights and active directory, so that the user's operation is limited to the appropriate scope, thus ensuring the security and reliability of the entire server. The other is the client, given the current market share of the handheld terminal operating system is Android, through the Android client. Three core modules, including login modules, downloading file modules and uploading file modules, can be easily uploaded to private cloud servers by client home users, and files from private cloud servers are downloaded to handheld terminals.
Finally, by deploying vsftpd servers on the virtual machine, the whole system restricts the user's rights and main directories by configuring files, and installs the client on the handheld terminal, enabling the file to be uploaded and downloaded safely and reliably.
