Cryptographically properties of random S-boxes
No full textThe results of studies of the properties of random permutations carried out with the participation of the authors are generalized. It is shown that random substitutions overwhelmingly have good cryptographic, and in particular, algebraic properties. The prospects of using random S-blocks to build block symmetric ciphers with improved dynamic rates of arrival to random substitution are substantiated. A refined model of random substitution and the corresponding criteria are proposed, with the help of which one can verify the suitability of substitutions generated randomly for use in modern cipher designs. It is a check, since with a very high probability the checked substitutions will be suitable

New wave simulations to the (3+1)-dimensional modified Kdv-Zakharov-Kuznetsov equation
No full textInternational Conference on Numerical Analysis and Applied Mathematics (ICNAAM) - SEP 19-25, 2016 - Rhodes, GREECEWOS: 000410159800577In this study, we apply an effective method which is improved Bernoulli sub-equation function method (IBSEFM) to the (3+1)-dimensional modified KdV-Zakharov-Kuznetsov equation. It gives some new wave simulations such as complex and exponential structures. We check up whether all structures verify the (3+1)-dimensional modified KdV-Zakharov-Kuznetsov model. Then, we plot three and two dimensional surfaces of obtained solutions by using Wolfram Mathematica 9

Global well-posedness for the Cauchy problem of the Zakharov-Kuznetsov equation on cylindrical spaces
Get PDFWe prove that the Zakharov-Kuznetsov equation on cylindrical spaces is
globally well-posed below the energy norm. As is known, local well-posedness
below energy space was obtained by the first author. We adapt I-method to
extend the solutions globally in time. Using modified energies, we obtain the
polynomial bounds on the growth for the global solutions.Comment: 24 page
Hiding data in the structure of the FAT family file system
No full textThe paper researched the methods of technical steganography, namely, based on the hiding of information messages in the structure of the FAT family file system. The basic method based on changing the numbering of cover files clusters is considered, its advantages and disadvantages are researched. An improved method is proposed that allows to significantly increase size of hidden data. The results of the comparative analysis of hiding data in the structure of the FAT family file system are given
