中文摘要 | 隨著電腦網路快速發展,形成企業網路、商際網路、網際網路以及公文電子交換 之新的使用環境模式,也產生有次序性結構或更複雜的存取共享資源需求。一些共享資源可 能會在某種有次序性的控制下才能被存取;在傳統的存取控制模式中只能表示各個使用者對 各個資源的存取控制,所以無法支援此種模式。在本文中將提出一種有次序性的存取控制模 式,即資源須在某種次序控制下的存取才被許可,若非在此種次序控制下的存取將不被許可 ;本文中並將該模式應用在分散式系統中;另對群組導向的存取控制,本文亦提出一個改良 方法,並將次序性存取的問題亦納入考慮之中。 |
英文摘要 | With the rapid development of computer networks that brings about many new user-environmets of INTRANET, EXTRANET, INTERNET, and missive electronic transfer. The need comes into being for information sharing access by the mechanism of the order condition. Some shared resource may be accessed only under some order conditions. The convnetional mechanisms of access control can only handle the control operation which permits each resource for each user, so it cannot support this type of access control. In this paper, we present a model called the "order-oriented access control model" in which the operation of access permitted to each resource must be done under some order conditions; otherwise it will be denied. In this paper we also apply this model to distributed systems. For the group-oriented access control model, we also present a method for improvement and take into account the order condition. |
