| dc.description.abstract (摘要) | 對大部分的應用系統來說，在實施系統功能存取控管的同時，若沒有搭配適當的委任或委派權限的機制，將會大大影響系統用戶對存取控管限制的接受度，故本論文針對如何實現用戶間的權限委派進行探討。我們選擇以剖面導向技術開發的存取控管框架為標的，設計出一套模組化的權限委派機制，可以在不改變既有的存取控管剖面的情況下，進行用戶間的權限委派。我們採用動態剖面的技術，並結合個體層次的剖面功能，發展出可以在使用應用系統的交談期間，由用戶動態進行權限委派的啟動與關閉。此一操作方式不僅方便系統管理者進行存取控管與權限委派的設定，也讓用戶在使用上享有相當程度的彈性。我們以AspectWerkz的剖面框架為實驗平台，製作一個用戶間權限委派的展示系統。 | zh_TW |
| dc.description.abstract (摘要) | For many systems, access control without proper support for delegation is simply impractical. While access control has gained a considerable attention in the aspect-oriented community recently, delegation has not been properly addressed yet using aspects. This paper presents a simple yet novel approach to implementing delegation using dynamic aspects. This thesis shows that a proper combination of instance-level aspects and dynamic deployment can be used to enhance an aspect-based access control system with dynamic and fine-grained delegation effectively in a highly modular manner. We developed a prototype implementation using the per instance interception mechanism of AspectWerkz to illustrate our approach. | en_US |
