iTrust6G presents a Beyond 5G (B5G)/6G vision based on an intelligent fabric of technology enablers connecting human, physical and digital worlds. It proposes novel concepts and solutions, for a unified and intelligent security architecture for distributed network and cloud domains, capable of addressing advanced 6G use cases and applications, by integrating required architectural enablers for flexible yet cost-efficient deployment in 6G networks.

The project aims at designing and implementing a network architecture implementing zero-trust principles to increase the trustworthiness of 6G networks at several levels: AI/ML algorithm exploited for threat handling, asset compliance, explainable security policies and asset observability. The project aims to improve the accuracy and the efficiency of (i) methodologies used for trust determination (e.g., time to share cyber-threat intelligence, duration of the vulnerability assessment procedure, number of the assurance conformity check), (ii) the performance of the security procedures involved (e.g. number of classes of monitored resources, mean time-to-detection of threat, mean time-to-reaction), and (iii) the induced overhead over network resources exploitation (e.g., performance overhead due to the programmability models). iTrust6G will exploit AI/ML for security management purposes, (enacting security automation and contribute to the security of the service orchestration), trust management (via the trust assessment process), and at the control layer (for threat detection and mitigation purpose).
