Journal ArticleDOI
Chaos-on-a-chip secures data transmission in optical fiber links.
TL;DR: In this article, compact, fully controllable and stably operating monolithic photonic integrated circuits (PICs) that generate broadband chaotic optical signals are incorporated in chaos-encoded optical transmission systems.
Journal ArticleDOI
Physical Unclonable Function based on a Multi-Mode Optical Waveguide.
Charis Mesaritakis,Marialena Akriotou,Alexandros Kapsalis,Evangelos Grivas,Charidimos Chaintoutis,Thomas Nikas,Dimitris Syvridis +6 more
TL;DR: The proposed configuration enables the system’s response to be simultaneously governed by multiple physical scrambling mechanisms, thus offering a radical performance enhancement in terms of physical unclonability compared to conventional optical implementations.
Journal ArticleDOI
Towards a Scaleable 5G Fronthaul: Analog Radio-over-Fiber and Space Division Multiplexing
Simon Rommel,Delphin Dodane,Evangelos Grivas,Bruno Cimoli,Jérôme Bourderionnet,Gilles Feugnet,Alvaro Morales,Evangelos Pikasis,Chris G. H. Roeloffzen,Paul van Dijk,Michail Katsikis,Konstantinos Ntontin,Dimitrios Kritharidis,Izabela Spaleniak,Paul Mitchell,Mykhaylo Dubov,Juliana Barros Carvalho,Idelfonso Tafur Monroy +17 more
TL;DR: The use of analog radio-over-fiber (ARoF) is proposed and demonstrated as a viable alternative which, combined with space division multiplexing in the optical distribution network as well as photonic integration of the required transceivers, shows a path to a scaleable fronthaul solution for 5G.
Journal ArticleDOI
Transmission Effects in Wavelength Division Multiplexed Chaotic Optical Communication Systems
TL;DR: In this article, the influence of interference, channel polarization and cross-phase modulation on a chaotic optical communication system tested in an installed network environment is analyzed. And the efficiency of data recovery of the conventional and chaotic encrypted channels is analyzed, using forward error correction (FEC) methods.
Journal ArticleDOI
An OpenNCP-based Solution for Secure eHealth Data Exchange
Mariacarla Staffa,Luigi Sgaglione,Giovanni Mazzeo,Luigi Coppolino,Salvatore D'Antonio,Luigi Romano,Erol Gelenbe,Oana Stan,Sergiu Carpov,Evangelos Grivas,Paolo Campegiani,Luigi Castaldo,Konstantinos Votis,Vassilis Koutkias,Ioannis Komnios +14 more
TL;DR: The KONFIDO project approach is described and how it is being deployed via a combination of complementary security enhancing technologies with the ultimate goal of increasing trust and security of eHealth data exchange.
