Yuan Zhong-lan, Wen Qiao-yan · Journal of China Academy of Electronics and Information Technology · 2006
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.
