基于角色-任务-产品的企业知识访问控制模型

Enterprise Knowledge Access Control Model Based on Role-Task-Product

传统的计算机访问控制模型很难适应动态、异构的网络环境下企业知识访问控制。根据企业知识特征,提出一种基于角色-任务-产品的企业知识访问控制模型,并构建角色、任务和产品的本体作为模型逻辑推理基础,然后以汽车虚拟企业为例演示该模型的工作机制和过程,显示该模型能有效适应动态、异构的网络环境。

Traditional access control model of computer system is difficult to be adapted to enterprise knowledge access con-trol in dynamic,heterogeneous network environment.According to characters of enterprise knowledge,a role-task-product based enterprise knowledge access control model is presented,with ontology of role,task and product described which is log-ic engine of the model.Then a case of auto virtual enterprise is demonstrated,proving that the model is qualified for dynam-ic,heterogeneous network environment.
