分布式系统中的RBAC管理模型

RBAC Administration Model in Distributed Systems

针对在分布式环境下的RBAC管理问题,提出了一种新的分布式系统中的RBAC管理模型。该模型没有专门保存一个全局的RBAC访问控制策略,各子系统只是保存自身的访问控制策略。当策略发生改变后,模型中各子系统根据管理指令进行自身的策略改变,使整个分布式系统中的RBAC访问控制策略达到一致。

A new model was proposed to meet the problem of RBAC Administration in Distributed Systems. No globally RBAC access control policy has been store in this model and each subsystem just save its own policy. When the policy changes, the subsystems change its own access control policy by Administrative Commands, then make the RBAC Administration in Distributed Systems consistent.
