iTrust6G aims at designing and implementing a network architecture implementing the 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 prioject aims to improve the accuracy and the efficiency of the (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).
