Quantum threats to the security of banking business

The purpose of the study. To draw attention to the problem of loss of personal data, valuable assets in the digital banking business environment, as well as to search for areas to enhance the cybersecurity of the digital perimeter in the context of the development of quantum technologies.

The research methodology is based on the study of scientific and specialized literature, the analysis of which will allow us to take a fresh look at quantum technologies from the standpoint of implementation in the security system and prepare a theoretical basis for activating research in this area. The work used general scientific methods of analogy, generalization, logical analysis, systematization, which made it possible to determine the role of quantum technologies in the context of expanding the digital banking space.

Research results. A review of quantum achievements over the past 10 years has been conducted, in which the following main trends can be traced: quantum computing, quantum communications and networks, quantum sensors and metrology. An assessment of the results obtained in the development of quanta has proven that the world has approached the quantum transition and it is necessary to keep up with future changes. The point successes of individual countries and companies in quantum topics are accumulating and will be transformed into widespread use. Russia is participating in quantum international competition and is striving to build quantum-resistant communication networks.

Conclusions. A scheme for building a quantum-protected communication network for exchanging information flows in the digital space of the financial market is proposed. There is a problem of the impossibility of conducting quantum and information flows through one channel.

Originality. The study allows us to focus on the changes taking place in the information space and emphasize the attention the need to find solutions to enhance the protection of banks' digital assets using quantum technologies.
