Abstract:	隨網際網路與高科技的應用，帶動雲端系統成為不可或缺的科技趨勢，幾乎所有產業皆能看見雲端科技的應用，本篇論文著重於文教產業與雲端科技相互結合運用的發展；教師授課的方式由傳統的實體課程漸漸發展為數位授課，同時教師能夠選擇是否同步教學，而搭配教學的教材也由紙本教材也逐漸轉變為儲存於網際網路的數位教材；本論文提出將此類教育傳播模式建構於雲端平台，透過使用者合法的身分驗證，使用者便可取得其服務權限，不受時空的限制使用平台上的資源，此項發展儼然成為教育發展的新興趨勢。基於雲端數位教材之存取機制，對於授課端涉及教材本身的著作權與是否公開傳播的權利，平台中的使用者身分必須受到嚴格的管控與保護，透過身分驗證的方式，對其存取權限與隱私設定進行嚴密監控，以確保教與學雙方之權益；此外，系統也必須防止與避免任何來在外部或是內部的惡意攻擊，斷絕非法的單一使用者或是惡意團體入侵系統竊取使用者資料，因此本論文結合公開金鑰密碼系統(Public-Key Cryptsystems)的概念以及Lagrange插值多項式的數學特性，提出一個加密方式，此方式結合高度安全性與隱私性，加上高效率的動態權限存取機制，打造能夠讓教與學雙方使用者都能安心且方便使用的數位教學環境。 The application of Internet and high technology facilitate cloud systems to be the inevitable technological trend. The application of cloud technology covers up most industries. This study stresses on combining and applying to the education industry and cloud technology. The way that teacher instructs has is gradually developed from traditional physical courses into digital teaching. Meanwhile, teachers could choose for synchronous teaching. The teaching materials are also changed from paper-based materials into digital materials saved on the Internet. It is proposed in this study. We construct an educational communication model on a cloud platform; with legal authentication, users can acquire the service authority and use the resources on the platform without being restricted on time and at space. This development has become the rising trend for the development of education.Based on the access mechanism for digital materials on the cloud, people concern more about the copyright of the materials and the right for public communication on the instruction end. User identification on the platform must be strictly controlled and protected. Authentication should severely control the access authority and privacy setting to ensure the rights of teachers and learners. Moreover, the system should prevent the attack from both external or internal to stop illegal single users or malicious groups intruding the system for stealing user information. In this case, we proposed the idea of public-key cryptsystems and the teaching characteristics of Lagrange interpolation polynomial are integrated in this study. The encryption combines high security and privacy. The mechanism that accesses the high-efficiency dynamic authority allows users a securely and conveniently using the digital teaching environment.
