GGRA: a grouped gossip-based reputation aggregation algorithm
An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...
متن کاملDisTriB: 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 کاملA Generic Framework for Modeling Decentralized Reputation-based Trust Models
Decentralized applications do not have a single centralized authority that can safeguard peers in the system from malicious attacks. Each peer is autonomous and must adopt measures to protect itself. Reputation-based trust management systems enable peers to develop trust relationships with each other based on their reputations. These trust relationships help a peer determine the trustworthiness...
متن کاملBehavioural Evaluation of Reputation-Based Trust Systems
In the field of trust and reputation systems research, there is a need for common and more mature evaluation metrics for the purpose of producing meaningful comparisons of system proposals. In the state of the art, evaluations are based on simulated comparisons of how quickly negative reputation reports spread in the network or which decision policy gains more points against others in a specifi...
