Towards Secure 5G Service Marketplaces: A review of “an SLA-driven Trust and Reputation Management Framework” [Póster]

Abstract

In the 5G era, marked by an expansive network of stakeholders, resources, and services, establishing trust in distributed marketplaces is crucial to ensure fruitful business agreements. 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.
