6G Networks: Trust Controller Architecture Proposal

The evolution towards 6G networks introduces significant challenges in trust management due to the increased complexity and multi-vendor nature of these systems. This paper proposes a comprehensive Trust Controller architecture within a Trust Manager framework to address these challenges. Utilizing Blockchain technology, the Trust Controller ensures transparency, immutability, and verifiability of trust-related data. The proposed system calculates and manages the trustworthiness of service providers by mainly integrating objective metrics. Additionally, this paper outlines a model for trust computation in a multi-stakeholder 6G environment, aiming to enhance service reliability and security.
