Role-Mining Optimization with Separation-of-Duty Constraints and Security Detections for Authorizations

Future Internet, 2019
Role-based access control (RBAC), which has been regarded as one of the most popular access-control mechanisms, is featured by the separation-of-duty constraints, mutually exclusive constraints, and the least-privileges principle.

一种改善RBAC模型用户权限获取效率的方法

四川大学学报. 自然科学版, 2009
针对RBAC模型中用户权限获取的性能瓶颈问题,通过对用户权限获取方式的分析,找到了产生性能瓶颈的原因。结合数据冗余的思想,引入同名用户存储用户在系统中的静态权限集,改进了RBAC模型结构,调整了权限获取和管理流程,提出了同名用户角色访问控制(HU-RBAC)模型。该模型在实际应用中得到实现和验证。

分布式环境下的一种基于角色的访问控制模型

四川大学学报. 自然科学版, 2007
为将角色访问控制RBAC应用于分布式环境,本文研究了传统RBAC角色组织结构,在倒转树型角色组织结构的基础上引入域的概念,将分布式系统中各机构封装成域.进而针对分布式系统的特殊性提出原始域和构造域概念,扩展了权限的概念,然后分别提出了域内和域间的访问控制策略.从而实现了RBAC的分散化和分布式管理.
