| 摘 要： | 针对现有访问控制模型在工作流系统安全方面存在的不足,提出一种基于角色和任务的工作流访问控制管理模型(ATRBAC).该模型将ARBAC模型中的管理思想融入TRBAC模型,并引入管理员及管理权限,同时对管理员实行层次管理,解决了系统管理员的权限过大而产生的隐患,加强了系统的安全性.

| Abstract: | To overcome the weaknesses of security existing in the old access control models of workflow systems,a new model called Administrative Model for Task-Role Based Access Control(ATRBAC) is presented in this paper.In this model the administrative idea of ARBAC(Administrative Model for Role Based Access Control) is integrated into the TRBAC(Task-Role Based Access Control) through adding administrator and administrative privilege.By applying hierarchical management on administrators,the hidden risk caused by the... |
