Keynote: Specification and conflict detection for GTRBAC in multi-domain environment

Abstract

Although the development and expansion for the time-based RBAC policy has enhanced the security greatly, there are hardly any paper paying attention to the conflicts that produced by the time feature in multi-domain RBAC model. In this paper, we focus on temporal constraints and the role inheritance constraints that occurred in the interoperation domains based on Petri nets. The approach can check whether an inter-domain access requirement has violated its local RBAC policy or the inter-domain access control policy has improper temporal constraints. In order to illustrate this approach, an applicable example is shown for the specification and conflict detection. © Springer International Publishing Switzerland 2014.
