Dr Thanassis Giannetsos, Head of UBITECH’s Digital Security & Trusted Computing Research Group, and his co-author introduce RETRACT, an innovative and comprehensive anonymous credential scheme, at the 18th International Conference on Availability, Reliability and Security (ARES 2023), that is held August 29 – September 1, 2023 in Benevento, Italy. In particular, RETRACT enables credential holders to demonstrate their possession of satisfying credentials for any given predicate, while ensuring that only the intended verifier can validate them.

After a peer review process, the scientific publication entitled “ZEKRA: Zero-Knowledge Control-Flow Attestation” has been accepted for presentation at the 18th ACM ASIA Conference on Computer and Communications Security (ACM ASIACCS 2023) that is held in Melbourne Australia from July 10th to July 14th, 2023. In this work, UBITECH’s Dr Thanassis Giannetsos (Head, Digital Security & Trusted Computing Research Group) and his co-authors propose a novel method of encasing a program-agnostic execution path verification task inside an arithmetic circuit whose correct execution can be verified by untrusted verifiers using a zero-knowledge proof system without the verifiers learning any secret inputs.

The final review meeting for the DataVaults H2020 research project was held on Tuesday, June 27, 2023, wherein the DataVaults consortium presented to the external reviewers and the project officer (PO) of the European Commission the final results of the project. The key goal of the project, that the consortium succeeded in accomplishing is the delivery of a novel framework and architecture that leverages personal data, coming from diverse sources to help individuals construct their unified personal data hub, collect at a single point all of their personal data in a secure and trusted manner, and retain ownership and control on what to share and with whom, also receiving compensation for the artifacts they place at the disposal of other third parties.

UBITECH hosts the virtual kick-off meeting of the CYGNUS Cypriot research project, officially started on June 1st, 2023. The project is co-funded by the “DUAL USE” action of the multi-annual development framework of Programmes RESTART for the support of Research, Technological Development and Innovation in Cyprus  (Grant Agreement No. DUAL USE/0922/0024) and spans on the period June 2023 – May 2025. The CYGNUS  project aims to deliver a dual use self-managing software platform targeting various civilian applications and usage scenarios under the frame of advanced areas’, citizens’ and neighbourhoods’ surveillance by using UAVs with high-precision detection modules for object(s), person(s) or vehicle(s) with georeferencing capabilities. CYGNUS will follow a product-oriented methodology (M) for realizing a self-managing software platform putting the human-in-the-loop of the decision-making process and supporting the entire Big Data and Causal Intelligence lifecycle from the IoT / Edge to the Centralized Computing.

A scientific paper edited by researchers of University of Nicosia, INNOV-ACTS and UBITECH has been accepted for presentation at the 19th Annual International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT 2023) that takes place in Cyprus, at the Coral Bay near the city of Pafos. UBITECH’s Dr Sofia Karagiorgou (Head, Privacy-preserving Distributed Machine Learning Research Group) and her co-authors introduce a novel interactive and realistic VR-based serious game for training law enforcement officers in the analysis and understanding of terroristic activities.

After a peer review process, a scientific paper from UBITECH’s Digital Security and Trusted Computing research group has been accepted for publication at the 19th Annual International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT 2023) that takes place in Cyprus, at the Coral Bay near the city of Pafos. UBITECH’s Dr Dimitrios Papamartzivanos, Entso Veliou, Dr Thanassis Giannetsos (Head of Group) and their co-authors suggest that the usage of explainable artificial intelligence (XAI) can lead to even more efficient performance as they tackle the limitation of conventional black box models, by enabling the understanding and interpretation of a model’s operation.

UBITECH participated at DEFEA 2023, a high-profile international defence exhibition where international companies presented land, naval, aerospace, national and cyber security defence systems,which was held in the Metropolitan Expo facilities, Athens, on May 9-11, 2023. The exhibition included over 300 exhibitors from 22 countries and counted over 12000 visitors from 54 countries over 3 days, and concluded with great success, and it was an excellent opportunity for UBITECH to communicate the company’s cyber security R&D expertise and solutions. UBITECH’s presence attracted the interest of the participants (both visitors and other exhibitors) who had the chance to visit the stands of the company and get informed about the company’s expertise, the innovative solutions being developed in-house and also the relevant research projects.

Dr Thanassis Giannetsos, Head of UBITECH’s Digital Security & Trusted Computing Research Group, and his co-authors present an extended comparative technical evaluation of PKI and DAA-Based Architectures for V2X Communication Security at the 2023 IEEE Vehicular Networking Conference (VNC) that is held from April 26-28, 2023, in Istanbul, Türkiye. In particular, as the emerging Cooperative Intelligent Transportation Systems (C-ITS) landscape is expanding in terms of security and trust requirements, to provide the necessary enablers for the safety of critical operations (i.e., collision avoidance), Public Key Infrastructure (PKIs) and Direct Anonymous Attestation (DAA) schemes have been proposed by the literature, in order to provide authenticity over the exchanged messages. DAA schemes can help address several challenges of centralized PKIs by offering a more scalable solution for pseudonym certificate reloading and revocation.
