Title: Using Historical Role to Speed up Subsequent Negotiations
Abstract: Trust negotiation (TN) is an approach to establish trust between strangers through iterative disclosure of digital credentials. Speeding up subsequent negotiations between the same negotiators is a problem worth of research. This paper introduces the concept of visiting card, and presents a historical role based trust negotiation model (HRBTN). HRBTN creates an account for the counterpart at the first negotiation. When the negotiators construct a new credential disclosure sequence in a trust negotiation, both negotiators records the roles designed to the counterpart according to the credentials disclosed in the negotiations associated with the credential disclosure sequence constructed in the negotiation in his HIB. When they conduct a new negotiation, the resource provider checks that if the requester has a role that is permitted to access the resource. If such a role exists, the negotiators can disclose credentials according to the credential disclosure sequence associated with the role, instead of recalculating them again. HRBTN speeds up subsequent negotiations between the entities that interact with each other frequently without impairing the privacy preservation.
