Trust-based Access Control Model in Multi-domain Environment
نویسنده
چکیده
Access control is a process which control users to execute some operations of access some network resource according to the users identify of attribution. This paper analyzes current access control model, and extends the RBAC (role based access control) model, and based on which we propose a trust based access control model in Multi-domain environment (MDTRBAC). Design a heap-based trust management mechanism for MD-TRBAC Model, which is used to control the cross-domain access resource among different domains. The MDTRBAC model can provide more security, flexible and dynamic access control mechanism, and therefore improve both the security and the reliable of authorization mechanism.

The research communitiy has shown considerable interest in studying access control in single Trusted Operating Systems (TOS). However, interactions among multiple TOSs have attracted relatively little attention. In this paper, we propose a Collaborative Role-Based Access Control (C-RBAC) model for distributed systems in which accesses across system domain boundaries are allowed. Access entities...
