Abstract
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.
