We need models of trust to facilitate cooperation in multi-agent systems, where agents, human and artificial, do not know each other beforehand. This paper lists and proposes simple mechanisms for trust acquisition based on a very basic and general definition of trust, making no assumptions on the internal cognitive models of the involved agents. We also show how trust acquired one-on-one can b...

The aim of this paper is to present a logical framework in which the concepts of trust and reputation can be formally characterized and their properties studied. We start from the definition of trust proposed by Castelfranchi & Falcone (C&F). We formalize this definition in a logic of time, action, beliefs and choices. Then, we provide a refinement of C&F’s definition by distinguishing two gene...

This paper concerns reputation and trust computation in vehicular ad hoc networks (VANETs). Various survey and implemented work has been studied and analyzed to form a new survey on trust model to VANET. In this survey it is observed that there are lot of new techniques are possible to form a new trust model in VANET to provide better security with trust concern over the entire environment of t...

Currently, the cloud computing is hot research both in scholars and enterprise, because of its good features such as low investment, easy maintenance, flexibility and fast deployment, reliable service. But to truly implement cloud computing, we need to gradually improve it in academic, legal and institutional. Especially, the issue of trust is one of the biggest obstacles for the development of...

In this paper we present a generic model of trust for electronic commerce. The basic components of the model are party trust and control trust. We argue that an agent’s trust in a transaction with another party is a combination of the trust in the other party and the trust in the control mechanisms for the successful performance of the transaction. The generic trust model can be used for the de...

In this paper, we consider the influence of trust on the assimilation of acquired information into an agent’s belief. By use of modal logic tools, we characterize the relationship among belief, information acquisition and trust both semantically and axiomatically. The belief and information acquisition are respectively represented by KD45 and KD normal modal operators, whereas trust is expresse...

In this paper, we consider the influence of trust on the assimilation of acquired information into an agent’s belief. By use of modal logic, we semantically and axiomatically characterize the relationship among belief, information acquisition and trust. The belief and information acquisition operators are respectively represented by KD45 and KD normal modalities, whereas trust is denoted by a m...

Trust dilution and trust fusion are two operators that are used to calculate transitive trust in a trust network. Various implementations of these operators already exist but are not fully motivated. In this paper we define the basic properties of these two operators by developing a trust algebra. We evaluate several new and existing models against the axioms of this algebra, amongst which a nu...
