    Development of a statistically reliable pseudorandom bit sequence
    (Lviv Polytechnic Publishing House, 2015) Mandrona, Maria; Maksymovych, Volodymyr; Kostiv, Yuriy; Harasymchuk, Oleh; Lviv State University of Life Safety; Lviv Polytechnic National University
    A statistically reliable pseudorandom bit sequence generator has been developed on the basis of additive lagged Fibonacci generator. Studies have been conducted into its the quality of its operation according to the criteria of systemic theoretical approach to the design of generators. The said criteria include: pulse repetition period, statistical characteristics, linear complexity, key information amount (length of key) and rate of response.

    Examination of optimal settings for a Gollman generator
    (Видавництво Львівської політехніки, 2013) Kostiv, Yuriy; Mandrona, Maria; Maksymovych, Volodymyr; Harasymchuk, Oleh; Malynovskiy, Yuriy
    The article provides the reader with the results of an examination of a Gollman generator with a fixed number of basic m-sequence generators and different values of degrees of their polynomial. The examination was conducted using NIST statistical tests. The results obtained thereby allow to optimise the settings of the generator with specified output pulse sequence settings.
