As part of the ongoing efforts under ENSURE-6G Staff Exchange Program funded by the Marie Skłodowska-Curie Actions (MSCA), Task 2.1 — Designing AI-driven security solutions for 6G — Ms. Rashmi Ratnayake from University College Dublin (UCD), Ireland, recently completed a one-month secondment at Vrije Universiteit Brussel (VUB) in Belgium.
This collaboration aimed to advance research on mechanisms that ensure the trustworthiness of blockchain data, with a particular focus on AI-based trust scoring frameworks. From 01 June to 30 June 2025, Rashmi joined the research team at VUB, engaging in productive discussions and knowledge exchange centered around trust modeling for IoT data in distributed systems.
During the secondment, the focus was on laying the groundwork for a machine learning pipeline capable of deriving trust scores for data stored or exchanged over blockchain infrastructures. This involved in-depth reviews of the current state of the art, initial architectural planning, and identification of challenges in feature representation and trust quantification in heterogeneous and potentially adversarial environments.
This secondment provided a valuable opportunity to develop foundational ideas, exchange interdisciplinary knowledge, and align efforts toward trustworthy AI-based systems for 6G networks. Rashmi expresses her sincere thanks to Prof. An Braeken and Mr. Pramitha Fernando for their warm hospitality and strong support throughout the stay at VUB.
This collaboration reinforces the ENSURE-6G project’s commitment to developing secure, trustworthy, and intelligent 6G infrastructure through international knowledge transfer and interdisciplinary collaboration.
