Immunity Investigation of Quantum Cryptographic Equipment for Information Protection in Information Telecommunication Systems

Evelin Y. Bushuev, S. E. Grychkin, E. P. Stroganova

In this paper we discuss the information protection in information telecommunication systems in which information is protected by a quantum-cryptographic method. Basic principles and purpose of the quantum key distribution were described, as well as the advantages of quantum cryptographic information security systems. We show the problems that arise when using information telecommunication equipment and discuss the problems of operating in real conditions of quantum-cryptographic information security equipment. The study of complex noise immunity and the analysis of the influence of environmental parameters on the quality of its functioning are presented. The immunity performance has been tested in accordance with the applicable standards by electromagnetic compatibility. There are shown the immunity performance criteria.

Fiber-Optic Communication System Operation Under Electromagnetic Fields Influence

S. E. Grychkin, Evelin Y. Bushuev, D. V. Bolotov +2 more

The article studies the influence of electromagnetic influence on a fiber-optic communication system with quantum cryptographic equipment. The developed test benches and methods of experimental study of the influence of electromagnetic effects on a communication system with quantum cryptographic equipment with fiber-optic communication line are presented. The results of experimental study of electromagnetic influence on the communication system with quantum key distribution and an optical cable are discussed. The results of studying showed that the influence of magnetic fields on the transmission of an optical signal through an optical fiber leads to a significant rotation of the plane of polarization, and therefore to errors and failures in the system with quantum key distribution. At the same time, the experiment showed that the influence of electric fields is insignificant. The obtained data emphasize the need to take into account the electromagnetic environment when designing and operating communication systems with a fiber-optic communication line

Влияние непреднамеренных электромагнитных помех на квантовые криптографические системы связи

Evelin Y. Bushuev, S. E. Grychkin, Строганова Елена Петровна

Рассматривается воздействие непреднамеренных электромагнитных помех на оборудование квантовой криптографической системы. Предложена методика испытаний и обсуждаются результаты экспериментального исследования влияния электромагнитных помех. Контроль функционирования системы основан на отслеживании как ключевых показателей квантового канала, так и показателей классического открытого телекоммуникационного канала, которые определяют качество функционирования системы связи в целом. Подчеркнута необходимость разработки специализированного национального стандарта в области электромагнитной совместимости. The impact of unintentional electromagnetic interference on quantum cryptographic system equipment is examined. A test methodology is proposed, and the results of an experimental study of the impact of electromagnetic interference are discussed. System performance monitoring is based on tracking both key quantum channel parameters and those of a classical open telecommunications channel, which determine the performance of the overall communication system. The need to develop a specialized national standard in the field of electromagnetic compatibility is emphasized.
