    Report published in the Proceedings of the National Conference on "Education and Research in the Information Society", Plovdiv, May, 2019In this paper, we propose a research on the modified alternating step generator implementation based on feedback with carry shift registers. The scheme is proposed by Schneier. We calculated the period of the derivative algorithm. The key gamma is statistically tested with NIST test suite. The result of the analysis shows that the output data are such a random physical phenomena generated.Association for the Development of the Information Society, Institute of Mathematics and Informatics Bulgarian Academy of Sciences, Plovdiv University "Paisii Hilendarski

    The need of software-flexible stream ciphers has led to several alternative proposals in the last few years. One of them is a new Pseudo Random Number Generator (PRNG), named N-adic Summation-Shrinking (NSumSG), which architecture is described in this paper. It uses N-1 parallel working slave summation generators and one N-adic summation generator, controlling the nonlinearity in the generator. The implementation, some properties and statistical tests of NSumSG are given. The results from statistical analysis show that the sequence generated by NSumSG is uniform, scalable, uncompressible, whit large period; consistent and unpredictable. This gives the reason consider the NSumSG as suitable for a particular cryptographic application

    Social work at the airport is in to offer to passengers social services. The main methodological position is that people are under stress, which characterized by a particular set of characteristics in appearance and behavior. In such circumstances passenger attracts in his actions some attention. Only person whom he trusts can help him with the documents or psychologically
