本研究計畫的主題在於研究代理人的可信度管理，首要的目標是建立一個以代理人為基礎的安全式電子交易環境。以目前的情況來看，唯有代理人的觀念及技術來執行電子商務仲介者的角色，利用軟體代理者具有自主性，及適時反應等特質，提供服務時的效益和彈性，再輔以適當的安全性管理及深入的可信度探討，電子商務才可能被具體應用到人類實際日常生活上。在作法上除了採用FIPA的規格作為代理人系統平台的實作標準，延伸XML/RDF來便利代理人的建構與溝通，更進一步結合X.509及SPKI/SDSI兩種類型憑證的優點，導入分散式認證授權的觀念，並透過RBAC的控管，形成多重代理人系統的安全架構。配合相關的信任策略及商務模型，以期完成建構一個以代理人為基礎可信任安全式電子交易環境的目標。 / This thesis describes an agent-based secure E-Commerce environment with distributed authentication and authorization services. The previous researches about security issues in agent-mediated E-commerce do not solve the problems of deals with strangers. We merge role based access control (RBAC) concept for adapting the certificates to different business models or new content-based network. Several types of agent delegation mechanism based on our role certificates and some considerations about how to achieve agent trust management with policies both in logics and practice are presented. Finally, We will demonstrate a scenario on FIPA OS system by using agent communication language (ACL) and content language (CL) encoded by XML and XML/RDF.
