A proposed reputation-based trust management framework aims to secure reliable transactions by analyzing behavior and predicting trust scores, further reinforced by an SLA-driven reward and punishment system for real-time trust adaptation. Demonstrated through real-life experiments in the 5GZORRO H2020 European project, this framework effectively identifies bad-mouthing attacks with 67% accuracy, even with significant recommender compromise, showcasing its resilience to misbehavior.application/pdf2engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/SecurityTrust Management5GDistributed marketplacesTrustworthy Relationshipsinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
