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。
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.
