Quantum Cybersecurity in 5G Networks (QUANTUM5) will practically demonstrate the application of Quantum Key Distribution (QKD) in 5G networks, providing sophisticated simulation tools and practical guidelines for further quantum technology convergence. Within the 5G network testbed installed on the campus of the VSB Technical University in Ostrava (Czech Republic), QUANTUM5 will integrate QKD technology to demonstrate secure 5G networking management concepts such as network function virtualization (NFV) and software-defined networking (SDN). The goal is to examine the adaptive ways of network organization and management of the network through the assurance of the 5G high-speed networking and continuous provision of information-theoretical levels of security.

Telecommunication networks are critical infrastructure for ensuring the proper functioning of social communities. With digitalization has become a more urgent need than ever, network communications that are easy to use and secure at the same time become crucial. Quantum networks have, compared to public-key cryptography secured systems, the appeal of handling most of the key-management matters transparently in the background, and due to using symmetric encryption, can work with longer-lived keys.

Quantum key distribution (QKD), based on the laws of physics rather than the computational complexity of mathematical problems, provides an information-theoretically secure (ITS) way of establishing symmetrical binary keys between two geographically distant users. The keys are secure from eavesdropping during the transmission and QKD ensures that any third party‟s knowledge of the key is reduced to a minimum which provides the quantum-resistant encryption. In recent years, noticeable progress in the development of quantum equipment has been reflected through a number of successful demonstrations of the QKD technology. While they show the great achievements of QKD, many practical difficulties still need to be resolved, especially from the point of view of network management and organization.

University of Sarajevo

The University of Sarajevo (UNSA) will be involved in modeling a 5G simulation module with support for QKD cryptography. Based on practical tests in the VSB 5G campus network and the 5G laboratory of the Department of Telecommunications, a new simulation model for 5G QKD networks will be developed.

Head of the research team in front of the University of Sarajevo doc.dr. Miralem Mehic emphasized that this is the first research project in the field of 5G and quantum cryptography in Bosnia and Herzegovina. It is of great importance for the University to acquire advanced knowledge and scientific experience. The project provides an opportunity for young researchers to participate in cutting-edge international research activities. It will open the door to use the acquired knowledge and experience, organize lectures and workshops with the aim of transferring knowledge about quantum and 5G technology in Bosnia and Herzegovina.

The total budget of the QUANTUM5 project is 257.000 EUR with a duration of three years.
