【摘要】 角色的私有权问题一直是RBAC中没有解决的问题。在分析现有的私有权解决方案的基础上,提出了角色的N阶继承方法,将角色的权限分为私有、保护和公有三类,对保护权限的继承进行了定义。为了能够将一个角色的非私有权限继承为私有权限,又提出了三种不同的继承模式:Private模式、Protected模式和Public模式。更多还原

【Abstract】 In present the research on private privileges in Hierarchical RBAC remains a fertile area.This paper analyses several current solutions for this problem and proposed a new role inheritance relation.We divide role privileges into private privileges,protected privileges and public privileges,then give a method for the hierarchy of protected privileges.We also proposed three hierarchy modes,namely private hierarchy mode,protected hierarchy mode and public hierarchy mode.In these modes,a senior role can inherit the public privileges or protected privileges of a junior role as private privileges.更多还原
