摘要：A trust negotiation is a mutual attribute -based authorization protocol between two entities.Trust Negotiation is an approach to regulate the exchange of sensitive information during this process. The proposed framework is a multisession dependable approach to trust negotiations. This framework supports voluntary and unpredicted interruptions, enabling the negotiating parties to complete the negotiation despite temporary unavailability of resources. The Trust-x protocol addresses the issues related to validity, temporary loss of data, and exte nded unavailability of one of the two negotiators. A peer is able to suspend an ongoing negotiation and resume it with another (authenticated) peer. Negotiation portions and intermediate states can be safely and privately passed among peers, to guarantee the stability neede d to continue suspended negotiations. Detailed analysis has been depic ted on Trust-x protocol which has seve ral key properties, including validity, correc tness, and minimalist. This system also withstands the most signific ant attacks. An ontology environment is also proposed to provide formal spec ification of concepts and their interrelationships. This is very essential in complex web service environments. It possesses the purpose of sharing information about cre dentials and their attributes, nee ded for establishing trust.
