ITrust6G

Understanding 6G as a network of networks (NoN) implies the participation of multiple stakeholders and the application of different technologies for the provision of any relevant service, and it raises several issues linked with procedures needed for the attachment and separation of the network domains, and procedures related to the proper and optimised operations of the E2E network service.

Network service orchestration procedures must consider the integration of networking solutions of different operators, limiting information exchange across domain boundaries, and considering the diversity in the lifetimes of the collaboration patterns, from short-lived ad-hoc arrangements, as in the case of V2X links, to semi-permanent ones, with the paradigmatic example of MNO interconnections. These scenarios require the establishment of trust links among the control planes of the integrated domains, as well as a consistent way of supporting confidentiality and integrity within and across their data planes. Dynamic security orchestration system operates across different layers of the 6G network, involving various stakeholders to ensure comprehensive security coverage.

iTrust6G will provide mechanisms for the dynamic establishment (and release, equally important) of trust links across administrative and technology domains. These mechanisms are rooted at a pervasive identity infrastructure that allows the identification of all entities in the network, combined with mechanisms for identity management through entity interactions and the application of zero-trust principles to dynamically assess the trust links to be applied. Whenever an end user accesses a digital service, iTrust6G will provide a dynamic assessment of the security postures of the interaction across multiple domains, ranging from the physical infrastructure (cell towers) to the network layers (telcos and MVNOs) and the service layer (service providers).
