An Evidence Based Architecture for Efficient, Attack-Resistant Computational Trust Dissemination in Peer-to-Peer Networks
نویسنده
چکیده
Emerging peer to peer (P2P) applications have a requirement for decentralised access control. Computational trust systems address this, achieving security through collaboration. This paper surveys current work on overlay networks, trust and identity certification. Our focus is on the particular problem of distributing evidence for use in trust-based security decisions. We present a system we have implemented that solves this in a highly scalable way, and resists attacks such as false recommendations and collusion.

A Genetic Programming-based trust model for P2P Networks
Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...
متن کاملAn Efficient Attack-Resistant Trust Model for P2P Networks
Building trust relationship between participants in a large-scale distributed Peer-to-Peer(P2P) file-sharing system is a challenging research topic because of peer anonymity, peer independence, high dynamics of peer behaviors, and the absence of an effective security mechanism. However, it is difficult to built trust simply by the traditional mechanism. Recommendation based trust models which a...
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 کاملGGRA: 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...
