Trust management and trust negotiation are prevailing approaches for establishing trust relationship in grid-based systems across security domains and inter-domains. In this paper, we propose TTN, a combining trust management with trust negotiation mechanism which provides the authorization and access control for the Scientific Data Grid and aims to enhance the grid security. The framework takes into account all aspects related to negotiations, from the policy language, negotiation protocol, strategy to algorithms used in negotiation. TTN presents a number of novel features, such as trust ticket that can speed up the negotiation, supporting different negotiation protocols to carry on a negotiation, the enhanced policy language for credentials and policies, as well as the trust management strategy and the optimal negotiation strategy. The results of experiments designed for our approach demonstrate the feasibility of TTN.
