The ACROSS project, in collaboration with the SNS JU projects NANCY, RIGOUROUS, and 6G-PATH, successfully concluded the joint webinar “Security & Trust in Multi-Domain 6G Networks.” The event brought together 4 SNS JU projects and over 60 participants, such as technical coordinators and researchers, to showcase the latest advancements in securing the next generation of telecommunications infrastructure.
ACROSS
Lluis Giffre (CTTC) introduced the project’s work on Software Defined Security, focusing on both static and dynamic traffic flow filtering and demonstrated how ACROSS utilizes a Network Digital Twin to train Machine Learning models capable of detecting “Heavy Hitters” and DDoS attacks. By leveraging the TeraFlowSDN controller, the system can automatically install Access Control Lists (ACLs) to mitigate these attacks in real-time, ensuring that only benign traffic reaches critical services.
Samira Briongos (NEC) presented Device/Container Attestation and Secure Migration. The presentation detailed the use of Remote Attestation utilizing TPM (Trusted Platform Module) and IMA (Integrity Measurement Architecture) enhanced by eBPF to verify the integrity of containers. Furthermore, the presentation covered Secure Migration, if a node is flagged as potentially compromised.
NANCY
Stylianos Trevlakis (InnoCube) shared results from their Quantum Key Distribution (QKD) simulator and testbeds, comparing COW3 and COW4 protocols. The team highlighted how simulation helps optimize transmission power and fiber length design guidelines to prevent eavesdropping in optical networks.
Javier Vicente (NEC) introduced NANCY’s privacy-preserving identity mechanisms, using Decentralized Identifiers (DIDs) and Verifiable Credentials, the project enables users to authenticate and access 5G services without surrendering full profile control to service providers.
Dimitrios Pliatsios (UoWM) demonstrated a secure inter-operator marketplace based on blockchain. This innovation allows for the creation of “Micro-Operators” that can dynamically trade computing and networking resources via smart contracts, significantly reducing energy consumption on the user equipment side.
RIGOUROUS
Antonio Skarmeta (UMU) detailed a framework that manages the full security lifecycle from onboarding to enforcement, using intent-based policies. The Cognitive Orchestrator, which translates high-level security intents into concrete policies across different domains and the integration of Federated Learning for privacy-preserving anomaly detection, allowing the network to reactively and proactively mitigate threats through automated “self-healing” mechanisms.
6G-PATH
Tarik Taleb (RUB) presented the MURAL (Multi-Domain Intelligent Resource Orchestration), which decouples intelligence from enforcement, creating an AI-native platform where scheduling algorithms can be upgraded without disrupting the system, this allows developers to build applications and analyze complex system logs using natural language, significantly lowering the barrier to entry for managing complex multi-domain cloud environments.
We would like to thank our partners from ACROSS, NANCY, RIGOUROUS, and 6G-PATH for their collaboration and their insights during the webinar.
