Novel and Flexible Approach to Trust Negotiations
Main Article Content
Abstract
Within the progress of society today Current real applications require flexible approaches to trust negotiations, especially in light of the widespread use of mobile devices. Moreover the ubiquitous nature of online peer-to-peer systems, and the increasing number of moving objects involved in online transactions, negotiators must be allowed to switch roles to guarantee dependability, availability of resources and peers. Existing method mostly focused on the assurance of privacy and confidentiality with the goal of guaranteeing that no actual information about a negotiator’s properties is disclosed. In this paper, we introduce a novel approach to trust negotiations that offers a general solution to those issues by developing major extensions to previous approaches by presenting a multi session dependable approach to trust negotiations. This proposed framework supports voluntary and unpredicted interruptions, enabling the negotiating parties to complete the negotiation despite temporary unavailability of resources. In our approach the protocols address issues related to validity, temporary loss of data, and extended unavailability negotiators. For increasing robustness and efficiency we showed how our negotiation protocol can withstand in most significant attacks.
