基于角色的访问控制在WFPN模型中的实现

The Implementation of Role- Based Access Control in the WFPN Model

大多数现存工作流系统缺乏如验证、网络安全等基本安全服务 ,本文研究了基于角色的访问控制并应用于WFPN模型 :首先定义了扩展的RBAC模型及WFPN模型 ,然后描述了安全机制的实现过程 ,最后采用COTS技术来实现我们的系统结构。

Most of existing workflow systems are lack of basic security services such as the authentication of users and network security. In this paper,we dissuss an experiment of injecting RBAC into the WFPN model. First, we define a modified RBAC and a WFPN model,then describe the implementation of the security mechanism to be applied in our model. Finally, we implement our system architeture by using the COTS technology.
