Fast secure calculation of the open key cryptography procedures for IoT in clouds / Mirataei Alireza, Markovskyi Oleksandr, Haidukevych Maria // Information, Computing and Intelligent systems. – 2022. – No. 3. – Pp. 56–62. – Bibliogr.: 16 ref.https://ela.kpi.ua/handle/123456789/54736The article proposes a method for accelerating the implementation of cryptographic data protection mechanisms on embedded IoT terminal microcontrollers, the basic operation of which is the modular exponentiation of high-capacity numbers. The method is based on the use of remote computer systems to speed up calculations and provides protection against the reconstruction of the secret keys of cryptosystems from data transmitted to the cloud. It has been theoretically and experimentally proven that the method allows, on average, 50 times, to speed up the implementation of cryptographic data protection protocols in IoT while providing a level of security sufficient for most practical applications.enmodular exponentiationsecure cloud computingIoT securityRSA cryptosystemsArticlePp. 56-62https://doi.org/10.20535/2708-4930.3.2022.265479004.056.50000-0002-4732-70300000-0003-3483-42330000-0003-2334-2401
