Trust Transfer in Distributed Systems
نویسندگان
چکیده
Trust transfer is a common technique employed in trust management systems to establish relationships between parties that are strangers. It is also well known that trust is not always transferable. That is, given an existing trust relationship, it may or may not be possible to derive new trust from it. In particular, it is not known under which constraints trust is transferable. In this paper we investigate trust transfer and identify when trust is transferable. Our analysis starts with a simple trust model. By using the model, we find that trust transfer is related to trust policy entailment. We then present a modal logic system which captures how trust and beliefs evolve in distributed systems. With the modal logic system we identify the key constraints on trust transfer regarding the communication between the trustor and the recommender and the trustor’s belief state.

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...

متن کاملP2P Network Trust Management Survey
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...
متن کاملfiletsf: A File Transfer System Based on lpr/lpd
In a distributed computing environment, it is often necessary to transfer files between machines for administrative or record keeping purposes. Most methods of file transfer either require full-scale trust by the recipient (e.g., rdist, rcp), the use of a ‘‘secret’’ password (e.g., FTP), or some level of pre-arrangement (e.g., rdist, track). This paper describes filetsf, a generic file transfer...
متن کاملOn Efficiency of Non-Monotone Adaptive Trust Region and Scaled Trust Region Methods in Solving Nonlinear Systems of Equations
In this paper we run two important methods for solving some well-known problems and make a comparison on their performance and efficiency in solving nonlinear systems of equations. One of these methods is a non-monotone adaptive trust region strategy and another one is a scaled trust region approach. Each of methods showed fast convergence in special problems and slow convergence in other o...
