    Effectiveness evaluation of modified block ciphers using standardized NIST statistical tests
    (Lviv Polytechnic Publishing House, 2015) Ihnatovych, Anatoliy; Lviv Polytechnic National University
    This research work proposes peculiarities of construction of modified block ciphers on the basis of inclusion of masking symbols. The analysis of effectiveness of the proposed block ciphers using the National Institute of Standards and Technology (NIST USA) statistical tests is done. Increasing of block ciphers’ effectiveness is described.

    Моделі застосування модифікованих блокових шифрів у кіберфізичних системах
    (НВФ «Українські технології», 2015) Ігнатович, А. О.
    За результатами аналізу особливостей та характеристик відомих блокових шифрів запропоновано моделі підвищення їх ефективності та надійності в кіберфізичних системах на основі статичного та динамічного включення маскуючих символів. Обґрунтовано підвищення ефективності та надійності блокових шифрів. This research work proposes models of efficiency and reliability increasing of the certain block ciphers. The proposed models are based on the basis of static and dynamic inclusion of masking symbols. Also the analysis of effectiveness of the certain block codes is done. Increasing of block ciphers’ strength and effectiveness is justified.
