| 摘 要： | 为了解决基于角色的访问控制模型(RBAC)在协同工作方式下与工作流结合的角色冲突问题,降低授权管理的复杂性,降低管理开销.以RBAC为基础,提出了基于扩展角色的访问控制模型(ARBAC),模型中工作流的角色授权同时受时间、行为和环境3个方面约束,提高了协同工作状态下访问控制的安全性,提升协同工作效益.结合实际的协同开发流程,表明了该模型的有效性和可行性.

| Abstract: | To solve the traditional role-based access control models(RBAC) role conflict working together with the workflow in collaborative environment,reduce the complexity of authorization management and costs of management.Based on RBAC,an augmented role-based access control model(ARBAC) is proposed,improving the cooperative work under the status of security access control.Role of workflow is under the control of time,behavior and environmental at the same time.The validity and the feasibility of the model are pro... |
