A new article, entitled “Towards Blockchain-Based Fog and Edge Computing for Enabling Privacy-Preserving Smart Cities”, has been published in Frontiers in Sustainable Cities, section Smart Technologies and Cities, thanks to the collaborative work done in the DataCloud H2020 Research and Innovation Action. UBITECH’s Giannis Ledakis and Ioannis Plakas, and their co-authors from SINTEF, TELLU (Norway), IEXEC (France) and JOT (Spain), discuss a variety of modern technologies for Smart Cities and proposes our integrated architecture, which connects Blockchain technologies with modern data analytic techniques (e.g., Federated Learning) and Edge/Fog computing to address the current data privacy issues in Smart Cities.

On 15 September 2022, the final review meeting of  SPIDER H2020 was held in Athens, Greece, with the physical presence of the majority of the Consortium partners as well as the external reviewers and the project officer from the European Commission side. The meeting was organized in hybrid form, allowing partners with restrictions on travel, to also join digitally. UBITECH was in charge of the technical coordination of the entire project activities, as well as task leader, responsible for the conceptualization and design of the platform architecture; development of the 5G threat knowledge base and incident repository; and integration as well as evaluation of the different components and interfaces of the SPIDER 5G Cyber Range.

NOVA and UBITECH ENERGY co-host the kick-off meeting in Athens, Greece (September 14-15, 2022) of the ENFLATE Innovation Action, officially started on September 1st, 2022. The project is funded by European Commission under Horizon Europe Programme (Grant Agreement No. 101075783) and spans on the period September 2022 – August 2026. ENFLATE aims at developing and demonstrating in six demonstration campaigns across five countries, a collaborative platform of tools enabling consumer-driven business models for energy services, valorising their multi-vector flexibility potential, integrating them with other non-energy services (cross-industry services), like health and mobility ones.

UBITECH participated at the kick-off meeting hosted by EURECAT in Barcelona, Spain (September 14-15, 2022) of the NebulOus Research and Innovation Action, officially started on September 1st, 2022. The project is funded by European Commission under Horizon Europe Programme (Grant Agreement No. 101070516) and spans on the period September 2022 – August 2025. NebulOus aims to transparently manage all the layers of the cloud continuum stack, in an equivalent manner to an Operating System (OS), managing the available computing capacity to facilitate an adaptive application hosting environment, driven by the processing proximity to data sources and optimised based on the data involved, the defined QoS requirements and the regulatory, security or privacy constraints.

UBITECH successfully concluded the DOOR project (Hardware Roots of Trust as an Enabler of Trustworthiness in Digital Transactions) that empowers participating entities in the ESSIF-Framework to establish trust by providing strong verifiable evidence and assurances on the origin and integrity of the presented verifiable credentials. DOOR achieves this goal by building a trusted layer between interacting parties that is based on strong cryptographic privacy-preserving tools. In this way, DOOR can enable the handling of VCs requiring higher level of assurances locally at the holder’s wallet.
