Мы предлагаем использовать блокчейн для создания неизменяемой записи событий безопасности, а смарт-контракты – для автоматического реагирования на подтвержденные угрозы. Вариационная квантовая схема (VQC) лежит в основе гибридной квантово-классической модели нашей системы. VQC обрабатывает информацию путем преобразования классических данных в квантовые состояния, использования параметризованных гейтов для моделирования сложных зависимостей и последующего измерения результата для его классификации. Мы используем метод «Один против всех» (OvR) для обнаружения сетевых атак, таких как Botnet, Brute Force и сканирование портов. Мы протестировали ее производительность как в идеальных (бесшумных), так и в симулированных шумных квантовых средах. Точность модели составила 93% в среде без шума и лишь незначительно снизилась до 92% в шумной среде, что демонстрирует ее устойчивость. Мы выявили существенный компромисс: метод OvR эффективен, но требует значительных вычислительных затрат. Это указывает на то, что последующие усилия должны быть сосредоточены на создании более эффективных систем квантовой многоклассовой классификации.</p></abstract><trans-abstract xml:lang="en"><p>This paper describes a security framework that uses both blockchain technology and quantum-enhanced anomaly detection. We propose use of blockchain to create an unchangeable record of security events and smart contracts to automatically respond to threats that have been confirmed. A variational quantum circuit (VQC) is the basis for our system's hybrid quantum-classical model. The VQC processes information by turning classical data into quantum states, using parameterized gates to model complicated dependencies, and then measuring the result to classify it. We use a One-vs-Rest (OvR) method to find network attacks like Botnet, Brute Force, and Port Scan. We tested how well it worked in both perfect (noiseless) and simulated noisy quantum environments. The model was 93% accurate without noise and only 92% accurate with noise, which shows that it is strong. We found a major trade-off: the OvR method works well, but it costs a lot of computing power. This indicates that subsequent efforts should concentrate on creating more efficient quantum multiclass classification frameworks.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вариационная квантовая схема (VQC)</kwd><kwd>сетевые аномалии</kwd><kwd>гибридная квантово-классическая архитектура</kwd><kwd>многоклассовая классификация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>variational quantum circuit (vqc)</kwd><kwd>network anomalies</kwd><kwd>hybrid quantum-classical architecture</kwd><kwd>multi-class classification</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">Anita, N., Vijayalakshmi, M., and Shalinie, S.
