По результатам математического моделирования установлены зависимости достоверности принятых данных от среднего времени однофотонной передачи информации. Выполненные исследования показали, что с ростом среднего времени однофотонной передачи информации эти зависимости растут, достигая насыщения. Причем прочих равных параметрах с ростом средней длительности мертвого времени продлевающегося типа насыщение происходит при больших значениях среднего времени однофотонной передачи информации.</p></abstract><trans-abstract xml:lang="en"><p>Expression for estimating the reliability of information during its transmission through quantum-cryptographic communication channel that contains a dead time photon counter has been obtained in this research. According to the results of mathematical modeling, the dependence of the reliability of the received data on the average time of single photon transmission of information was established. Studies have shown that with an increase in the average time of single photon transmission of information, these dependences grow, reaching saturation. Moreover, with equal parameters with an increase in the average duration of the dead time of a prolonging type, saturation occurs at large values of the average time of a single photon transmission of information.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>cчетчик фотонов</kwd><kwd>мертвое время</kwd><kwd>квантово-криптографический канал связи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photon counter</kwd><kwd>dead time</kwd><kwd>quantum cryptographic communication channel</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дмитриев, С.
