Trust-X: A System for Trust Negotiation in Open Systems

October 1, 2004 rychirko

In this talk, we will present Trust-X, a comprehensive XML-based framework for trust negotiations. Trust negotiation is a promising approach for establishing trust in open systems like the Internet, where sensitive interactions may often occur between entities at first contact, with no prior knowledge of each other. The framework we propose takes into account all aspects related to negotiations, from the specification of the profiles and policies of the involved parties to the selection of the best strategy to succeed in the negotiation. Trust-X has a number of innovative features, such as the support for protection of sensitive policies, the use of trust tickets to speed up the negotiation, and the support of different strategies to carry on a negotiation. In this talk, besides presenting the language to encode security information, we present the system architecture and algorithms according to which negotiations can take place and we outline on-going work.
