Trust and role based access control for secure interoperation (“TracSI”)

An important requirement of emerging systems is to be able to share information with other systems over open environments. When a system needs to allow previously unknown entities to access its resources, mechanisms should be in place to allow negotiating trust and services based on pre-defined sharing requirements. We emphasize that a framework for requirements-driven secure interoperation is needed in a loosely coupled environment to facilitate two interacting domains to access each other\´s local resources through access control policy mapping between the domains. In this paper, we present a framework implementation for a trust and role based access control for secure interoperation ("TracSI"), which tightly integrates generalized temporal role based access control ("GTRBAC ") and policy mapping mechanism with an integrated, game-theory based trust and service negotiation process.
