    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.

    Zero-knowledge identification of remote users by utilization of pseudorandom sequences
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2022) Daiko, Ihor; Selivanov, Viktor; Chernyshevych, Miroslava; Markovskyi, Oleksandr
    The article theoretically substantiates, proposes and investigates an identification scheme based on the concept of "zero knowledge" using irreversible generators of pseudorandom bit sequences. Session passwords form a chain generated by selective sequence values. Secondary identification sessions are provided in the proposed scheme to counter attacks with the displacement of one of the remote interaction parties. The main elements of the proposed identification scheme are developed in detail: authorization procedures, primary and secondary identification.
