A Requirements-Driven Trust Framework for Secure Interoperation in Open Environments

A key challenge in emerging multi-domain open environments is the need to establish trust-based, loosely coupled partnerships between previously unknown domains. An efficient trust framework is essential to facilitate trust negotiation based on the service requirements of the partner domains. While several trust mechanisms have been proposed, none address the issue of integrating the trust mechanisms with the process of integrating access control policies of partner domains to facilitate secure interoperation. In this paper, we propose a requirements-driven trust framework for secure interoperation in open environments. Our framework tightly integrates game-theory based trust negotiation with service negotiation, and policy mapping to ensure secure interoperation.
