臺灣博碩士論文加值系統

雲端存取的特性包含了高擴充、高性能以及低成本，它已成為雲端存取的重要技術。然而，在其方便的雲端存取服務下，數據安全卻是一大隱憂。高達70%的用戶不願意將重要的數據放上雲端網路。且著名的雲端服務公司，如Google、Amazon、Linkup等公司，仍發生資料遺失的安全問題。
目前，有許多論文都在竭力解決雲端訪問等方法與應用，相反卻僅有少數研究人員在討論雲端數據丟失的解決方案。AES是一種有效的數據加密方法。RAID是一種高效率的硬碟冗餘陣列方法。我們在雲端存取中結合了這兩項技術，為使用者提供一數據更安全且更保密的存取方法。
另一方面，我們也提出雲端的一種應用。我們利用雲端系統，如 Openstack，建置無碟教室環境，此一系統可改善傳統無碟教室環境不具跨網段的能力，並能提供使用者登入管理及課程選單的功能。

Cloud storage features high concurrency, high scalability, high performance, and low cost. It has become an important technology for storage system.However, cloud storage service in addition to its convenience, has raised widespread worries for data security.up to 70% of users are still reluctant to place important data outside their control. Moreover, several famous cloud service providers like Google, Amazon, and Linkup have encountered security issues such as data loss.
There are many papers addressed the topic of cloud access method. On the contrary, very few researchers discuss the solution of data loss in cloud storage.AES is an effective data encryption method. RAID is an efficient data access and data redundancy method. We present a cloud access method by combining these two technologies. It provides customers a method that can access cloud data efficiently, provide data redundancy, and keep data confidential.
And In this research, we also propose a cloud application. We use cloud system, like Openstack, to implement diskless classroom environment. The proposed system improves traditional diskless classroon functionality of not being able to send data across network segment and also provide user login and course management capacities.
