چکیده

Given their fully distributed architecture, P2P networks allow the design of low cost and high availability systems but also pose new security problems. In these collaborative networks, security properties need to be ensured by the participants themselves. In this paper, we propose to detect and exclude misbehaving nodes to allow honest participants to enforce security properties. The proposed scheme is fully distributed. RÉSUMÉ. De par leur nature totalement distribuée, les réseaux pair-à-pair permettent de mettre en place des systèmes à faible coût et haute disponibilité mais posent également de nouveaux problèmes de sécurité. Dans ces réseaux collaboratifs, les propriétés de sécurité doivent être garanties par les participants eux-mêmes. Dans cet article, nous proposons de détecter et d’exclure des nœuds malveillants afin de permettre aux nœuds honnêtes de garantir des propriétés de sécurité. Le système proposé est complètement distribué.

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...

A Biologically-Inspired Type-2 Fuzzy Set Based Algorithm for Detecting Misbehaving Nodes in Ad-Hoc Wireless Networks

Implementation of routing protocols in mobile adhoc networks relies on efficient node cooperation. However, node misbehavior is a common phenomenon, thus, ad-hoc networks are subject to packet dropping, packet modification, packet misrouting, selfish node behavior, and so on. In this paper, a biologically-inspired type-2 fuzzy set recognition algorithm for detecting misbehaving nodes in an ad-h...

A Dynamic Reputation Management System for Mobile Ad Hoc Networks

Nodes in mobile ad hoc networks (MANETs) are mandated to utilize their limited energy resources in forwarding routing control and data packets for other nodes. Since a MANET lacks a centralized administration and control, a node may decide to act selfishly, either by refusing to respond to route requests from other nodes or deceitfully by responding to some route requests, but dropping the corr...

A cooperative watchdog model based on Dempster-Shafer for detecting misbehaving vehicles

In this paper, we address the problem of detecting misbehaving vehicles in Vehicular Ad Hoc Network (VANET) using Quality of Service Optimized Link State Routing (QoS-OLSR) protocol. According to this protocol, vehicles might misbehave either during the clusters’ formation by claiming bogus information or after clusters are formed. A vehicle is considered as selfish or misbehaving once it over-...

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 ...
