We propose an extendable hierarchical authorizationassignment framework and design effective role-registeringi role-applying and role-assigningprotocol with symmetric and asymmetric cryptographic systems. The model can be used to simplifyauthorization administration in a distributed environment with multiple applications.展开更多

This paper discusses and analyzes the industrial struc- tural changes of Hong Kong in recent decades as well as its future challenges and opportunities, The data and finding reveal that even though Hong Kong will face fierce competition from the Mainland＇s cities as the rise of China, the important role as a bridge between China and the rest of the world wilt brace Hong Kong itself under the OCTS for developing into a service hub for business and trade in the Asia-Pacific region.展开更多
公共部门改革所产生的制度压力使半自治机构对改革做出了策略性的回应。荷兰和法国的机构只对部分改革措施依令照做。而对于其他改革措施则抗拒不办,这些改革规则要么被操控了,要么是达成了折中意见。对于改革的服从程度不只取决于组织...公共部门改革所产生的制度压力使半自治机构对改革做出了策略性的回应。荷兰和法国的机构只对部分改革措施依令照做。而对于其他改革措施则抗拒不办,这些改革规则要么被操控了,要么是达成了折中意见。对于改革的服从程度不只取决于组织结构,还取决于行动主体间的资源与权力分配。本文对荷兰所实施的荷兰独立行政机构框架法(the Dutch Kaderwet ZBO)和法国的公共政策总体评估(the French Revision Generale des Politiques Publiques)进行了比较分析。这些机构改革竞争不只是发生在机构与其上级主管部门之间,而是更多地体现在部门之间。两个国家中的机构上级主管部门都倾向于支持他们的下属机构。在荷兰,与权力相关的问题争议最多;而在法国,与资金相关的问题争议最大。展开更多
文摘To meet the authorization administration requirements in a distributedcomputer network environment, this paper extends the role-based access control model with multipleapplication dimensions and establishes a new access control model ED-RBAC(Extended Role Based AccessControl Model) for the distributed environment. We propose an extendable hierarchical authorizationassignment framework and design effective role-registeringi role-applying and role-assigningprotocol with symmetric and asymmetric cryptographic systems.
