摘要: 通过分析RBAC模型在信息量巨大、信息资源变化频繁的应用系统中表现出的不足――安全维护代价过于繁重,提出了一种新的基于角色的访问控制模型―-ARBAC模型。该模型具有较低的安全维护代价,良好的安全控制效果,有效克服了RBAC模型在该类系统中存在的不足。

Abstract: This paper analyzes the drawback of role-based access control model that is onerous secure maintenance costs in the systems which have a large amount of highly updating frequently information. Based on this point, a new role-based access control model―-ARBAC has been proposed. This new model has lower secure maintenance costs, well secure control effects, and can effectively overcome the drawback of role-based access control model in the kind of the systems mentioned above.
