A Multi-Level Cross-Domain Access Control Model Based On Role Mapping

摘要

Inter-domain access control can guarantee the safety of resources sharing among different domains, role mapping is one of the key technologies which realizing access control. Traditional mapping mechanism, which involves congested traffic, has massive computational complexity and has a big traffic. In this paper, we proposed a cross-domain role mapping model under the circumstance of multi security level, which makes the resources and roles divided into different security levels, and establishes a hierarchy tree according to the different department that containing different roles and resources. With the help of interdomain level service, we achieve the goal of cross-domain access control. Compared with the existing researches, the model in this paper is more practical and secure.
