摘要 RBAC在工作流访问控制的应用中很难合理地为角色配置权限,而且无法表达复杂的工作流访问控制约束。在RBAC中引入任务和权的概念来解决上述两个问题,提出基于任务和双权角色的模型TDWRBAC,给出模型的定义和相关算法。 RBAC is rather difficult to assign permissions to roles reasonably and is unable to express constraint in complicated workflow access control. A new model TDWRBAC based on task and dual-weight is proposed to solve the two difficulties by introducing the concept of task and weight in RBAC and definitions and relative algorithm of the model are presented.
