Целью исследования является повышение эффективности выполнения задач агентами киберфизической системы при наличии агентов с неисправным или вредоносным поведением за счет установления доверенного взаимодействия между агентами и быстрого выявления вредоносного воздействия.Метод. Доверенное взаимодействие осуществляется с помощью технологии распределенного реестра и показателя уверенности агентов при коллективном решении. Новизна предлагаемого решения состоит в том, что информация о действиях агентов будет храниться и агрегироваться с использованием смарт-контрактов через заданные интервалы времени. Отдельный агент хранит локальную копию цепочки взаимодействия агентов, если несколько агентов взаимодействуют между собой, то они обмениваются информацией, хранящейся в их распределенном реестре.Результат. Для апробации предложенного метода была выполнена его программная реализация на языке программирования C++. Для проведения экспериментов использован сценарий коллективного восприятия агентами децентрализованной киберфизической среды в специализированной имитационной программе Contiki’s Cooja.Вывод. Метод, реализованный с помощью предложенных в работе решений, оказался эффективнее, чем метод на основе динамического расчета показателя уверенности. Предложенные решения можно применять не только в киберфизических системах, но и в других системах с децентрализованным управлением.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The purpose of the work is to increase the efficiency of the functioning of agents of a cyber-physical system in the presence of agents with incorrect or malicious behavior. The goal is achieved by establishing a trusted interaction between agents and quick detection of malicious impact.Method. Trusted interaction is carried out using distributed ledger technology and agent confidence indicators. The novelty of the proposed solution lies in the fact that information about the actions of agents is stored and aggregated using smart contracts at specified time intervals. Each agent keeps a local copy of the agent interaction chain. If several agents interact with each other, then they exchange information stored in their copies of the ledger.Result. To test the proposed method, we implemented it in C++. For the experiments, the scenario of collective perception by agents of a decentralized cyber-physical environment in a specialized simulation program Contiki Cooja was used.Conclusion. The method implemented using the solutions proposed in this work showed higher efficiency than the method based on the dynamic calculation of the confidence index. The proposed solutions can be applied not only in cyber-physical systems, but also in any other systems with decentralized control. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>доверенное взаимодействие</kwd><kwd>информационная безопасность</kwd><kwd>технология распределённого реестра</kwd><kwd>киберфизические системы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>truste interaction</kwd><kwd>information security</kwd><kwd>distributed ledger technologies</kwd><kwd>cyber-physical systems</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Минцифры России (грант ИБ, проект № 27/22-к).</funding-statement><funding-statement xml:lang="en">The study was financially supported by the Russian Ministry of Digital Development (IB grant, project No. 27/22-k).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Алгулиев Р.М., Имамвердиев Я.Н., Сухостат Л.В.
