Trust is becoming an increasingly important issue in large-scale distributed systems. Especially self-managed systems from the Autonomic and Organic Computing domains consisting of several cooperating entities have to rely on an automated estimation how reliable and trustworthy potential cooperation partners are. In this paper, we introduce a novel concept to represent trust among those entities....
This study describes and evaluates a novel trust model for a range of collaborative applications. The model assumes that humans routinely choose to trust their peers by relying on few recurrent presumptions, which are domain independent and which form a recognisable trust expertise. We refer to these presumptions as trust schemes, a specialised version of Walton's argumentation schemes. Evidence is...
Peer-to-peer (P2P) networks have shown great potentials in providing a wide range of services starting from simple file sharing to distributed computing. However, P2P systems present ominous threats due to its anonymous and dynamic nature. One feasible way to minimize the threats is to evaluate the trust and reputation of the interacting peers. Trust models have often been deployed in determining...
