Information Flow Control in Role-based Model for Distributed ObjectsInformation Flow Control in Role-based Model for Distributed Objectseng論文http://id.nii.ac.jp/1001/00011966/Journal Articlehttps://ipsj.ixsq.nii.ac.jp/ej/?action=repository_action_common_download&item_id=11966&item_no=1&attribute_id=1&file_no=1Copyright (c) 2001 by the Information Processing Society of JapanDepartment of Computers and Systems Engineering Tokyo Denki UniversityDepartment of Computers and Systems Engineering Tokyo Denki UniversityDepartment of Computers and Systems Engineering Tokyo Denki UniversityDepartment of Computers and Systems Masashi, YasudaKeiji, IzakiKatsuya, TanakaMakoto, TakizawaVarious kinds of distributed applications are realized by using object-oriented technologies.Object-oriented systems are composed of multiple objects which cooperate to achieve some objectives by passing messages.Object-oriented technologies are used to realize the interoperability among the applications.In addition to realizing the interoperability it is essential to make the system secure.The secure system is required to not only protect objects from being illegally manipulated but also prevent illegal information flow among objects.In this paper we discuss role-based an access control model in the object-oriented systems and how to resolve illegal information flow by using the roles.Various kinds of distributed applications are realized by using object-oriented technologies.Object-oriented systems are composed of multiple objects which cooperate to achieve some objectives by passing messages.Object-oriented technologies are used to realize the interoperability among the applications.In addition to realizing the interoperability,it is essential to make the system secure.The secure system is required to not only protect objects from being illegally manipulated but also prevent illegal information flow among objects.In this paper,we discuss role-based an access control model in the object-oriented systems and how to resolve illegal information flow by using the roles.AN00116647情報処理学会論文誌426171517222001-06-151882-77642009-06-29
