    Fast secure calculation of the open key cryptography procedures for IoT in clouds
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2022) Mirataei, Alireza; Markovskyi, Oleksandr; Haidukevych, Maria
    The 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.

    Organization of protected filtering of images in clouds
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2022) Mirataei, Alireza; Rusanova, Olga; Tribynska, Karolina; Markovskyi, Oleksandr
    The article proposes an approach to using cloud technologies to accelerate the filtering of image streams while ensuring their protection during processing on remote computer systems. Homomorphic encryption of images during their remote filtering is proposed to be carried out by shuffling rows of pixel matrices. This provides a high level of protection against attempts to illegally restore images on computer systems that filter them. The developed approach makes it possible to speed up the performance of this important image processing operation by 1-2 orders of magnitude.
