中文摘要 | 由於軟體科技的發展,企業為了配合軟體科技的發展而採用效能越高的硬體,但卻對企業整體帶來了採購以及維修成本增加。此時由分散式運算以及網格運算演進而來的雲端運算的優勢就逐漸顯現。使用雲端運算可以將現有的軟硬體設備虛擬化,企業只需要擁有夠快的網路以及可以上網的設備,即可進行使用,不再需要龐大的硬體開銷以及IT人員的維護。然而企業在導入雲端運算後,決定組織的成員該如何安全的存取資源成為很重要的議題。雲端運算由於其環境的特性,因此十分容易遭受到與網路相關的攻擊;本文利用Identity Based機制產生權杖(Token)改良以角色為基礎的授權機制的安全性,使其能夠更有效率的應用在雲端網路環境上,並透過群組的概念使企業之間的協同合作更為安全以及有效率,提供管理者一個安全的授權機制,讓企業能放心地使用雲端服務。 |
英文摘要 | As the software technology development, companies need more high performance hardware for business operations, and result in the high hardware and hardware maintenance costs. To solve the above problem, cloud computing which is the evolution of distributing computing and grid computing has gradually appear its advantage. Cloud computing can virtualize the existing software and hardware to reduce the costs. Thus, a company only needs a fast enough network and devices which can access the internet to build a cloud. In such situation, the company no longer needs a large hardware overhead and IT staffs. However, how to secure access to resource will be an important issue since the company adopts the cloud computing technology. It is because the cloud computing environment is vulnerable to network-related attacks. In this paper, we use the Identity Based Token to improve RBAC (Role Based Access Control) authorization mechanism and result in the more efficiency of cloud computing applications. Moreover, the collaboration between companies will be more safety through the group concept. Therefore, our authorization mechanism can provide users a secure cloud environment, and users can rest assured to use cloud computing. |
