Показано, как квантовые технологии повышают безопасность и эффективность этих методов. Предложенные схемы обеспечивают устойчивость к атакам классических и квантовых компьютеров, устраняя уязвимости традиционных методов генерации ключей. Рассмотрены примеры применения в защищённых сетях IoT, облачных вычислениях и распределённых системах. Результаты демонстрируют, что комбинация КРК с криптографическими схемами является перспективным решением для постквантовой эры.</p></abstract><trans-abstract xml:lang="en"><p>The paper explores approaches to ensuring information security using quantum key</p><p>distribution (QKD) in combination with classical cryptographic schemes: the Blom scheme,</p><p>Key Distribution Pattern (KDP), and the Lagrange scheme.
