Analysis and Modelling of Trust in Distributed Information Systems

چکیده
In this paper, we consider the analysis and modelling of trust in distributed information systems. We review the relations of trust relationships in our previous work. We discuss trust layers and hierarchy based on formal definition of trust relationship. We provide a set of definitions to describe the properties of trust direction and trust symmetry under our taxonomy framework. In order to analyze and model the scope and diversity of trust relationship, we define trust scope label under our taxonomy framework. We provide some example scenarios to illustrate the proposed definitions about properties of trust relationship. The proposed definitions are new elements of the taxonomy framework for enabling the analysis and modelling of trust. We provide some discussions about the life cycle of trust relationships. The proposed trust structure and properties are currently being used in the development of the overall methodology of life cycle of trust relationships in distributed information systems.

DisTriB: Distributed Trust Management Model Based on Gossip Learning and Bayesian Networks in Collaborative Computing Systems
The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
