This thesis addresses the significant security challenges posed by emerging 6G networks, where traditional perimeter-based models fail due to extreme scale, heterogeneity, dynamic resource allocation, and complex multi-domain architectures. Focusing on the iTrust6G project, it implements and validates a comprehensive trust management framework grounded in Zero-Trust principles. The work delivers a fully functional prototype, a reproducible automated deployment pipeline, and demonstrates the framework’s effectiveness through representative use-case scenarios. The results show how security policies can be enforced continuously, services isolated after incidents, and trust-based onboarding and provisioning of new services achieved in diverse operational environments.
