    Hash search organization in e-dictionaries using block ciphers
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2020) Markovskyi, Olexander; Humeniuk, Inna; Shevchenko, Olha
    The article is devoted to the problem of developing high-speed electronic dictionaries for systems computer translation. The method of organizing a high-speed electronic dictionary based on an ideal hash addressing, where the cryptographic cipher block acts as a hash transformation is proposed. This method was developed taking into account the multilevel memory structure of modern computer systems. It was testified theoretically and experimentally that the proposed organization of electronic dictionaries guarantees at least twice higher search rate compared to known technologies.

    Protected discrete Fourier transform implementation on remote computer systems
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2020) Mirataei, Alireza; Khalil, Hana; Markovskyi, Olexander
    Effective method of the discrete Fourier transform acceleration with the use of cloud computing is theoretically substantiated and developed. The reigning feature of the suggested method is homomorphic encryption of the input signals, which provides efficient protection during the remote calculation. It has been shown theoretically and experimentally that the proposed method allows one to 1-2 orders of magnitude to speed up the processing of signals while maintaining their confidentiality. The proposed method can be applied for effective signal stream processing in clouds.
