摘要
已有的RBAC多域互操作模型没有考虑互操作域不对等的操作需求和安全需求,不能很好地适用于多层应用中各层之间交互操作的场合。该文提出了适合多层应用交互特点的单向角色映射RBAC互操作模型,通过构造不同层次的互操作有向图,分析了单向映射模型的安全特性。该模型提供了更简单的多域互操作安全分析方法,能为多层应用各层互操作提供更可靠的安全保证。
Secure interoperation of multidomain empioying RBAC has been investigated for years. Most research work assumed a symmetry interoperation need of each domain, which can＇ t meet the situation such as interoperation among tiers of a multi-tier application. This paper brings forward a unidirectional role mapping modei, which is optimized for multi-tier applications. Using digraph related algorithm, it analyzed the favorable characteristic of the model in detail. The model can simplify the analyticai complex of secure interoperation and can provide a more trusted secure guarantee for applications.
