Annotation: This article is considering the basic principles of building information security complexes, which allow automatic distribution and usage of quantum keys. Required parts of such complex are described which are needed for the operation of complex as a whole and for quantum key distribution in particular. The authentication scheme for quantum protocol is chosen. The choice of quantum random number generator is justified and algorithm for such generator is developed. The problems of combining encryptors with quantum key distribution devices are indicated and requirements for the logical interface of their interaction are revealed. In addition, authors present results of the analysis of quantum devices’ traffic influence on the load of protected channel between encryptors.
