  • The algorythm of building of dissymmetric bigram cryptosystem,based on diophantine difficulty

    The objective need to improve information security systems in the conditions of information-telecommunication technologies developing is shown. A new area of NP-complete promplems of diophantine analisys is firstly researched, namely Tarry–Escott multigrade diophantine equation systems (MDES) of given dimension and degree. The theorems, that describe parametrical MDES parametric solution properties, required for the development of the algorythm of building of dissymmetric bigram cryptosystem, are given in the article. The author's theorem, which allows to develop information protection system (IPS) mathematical model as a cortege, containing diophantine probleme. A new approach to develop dissymmetric bigram cryptosystem(DBC) on the base of two-parametrical MDES solution, which generalize open key cryptosystem, is considered. Forward and reverse conversions based on parametrical solution are suggested tyo realize on such algorythm. A new concept of equivalence of ordered sets of numbers (parameters) of a given dimension and order is introduced to build DBC mathematical model, using two-parametrical MDES solution. Described mathematical model demonstrates application potential of diophantine equations for IPS with a high degree of reliability.

  • Development of an integral indicator of tourism potential assessment from the point of application of the cluster approach to tourism development

    The article presents the developed cognitive model of tourism potential assessment, which allows to determine the prospects of development within the specific territory of the tourism and recreation cluster. The article describes the approach to the development of an integral indicator of tourism potential assessment, which should allow to determine the prospects of development within a specific territory of the tourism and recreational cluster. As part of the construction of an integral indicator, an algorithm for developing a system of indicators for assessing the tourist potential of the territory, based on the cognitive structuring of knowledge about the object, was proposed. In order to determine the functionally significant links between the system "Tourist potential of the territory" and the external environment, the study analyzed the connectivity of the structure, based on the study of simplicial complexes. As a result, a ranked list of factors of the "Tourist potential of the territory" system was obtained and the weight for each of them was determined, which allowed to form an integral indicator of the tourism potential assessment

  • Forecasting the number of employees in the Russian economy, taking into account the impact of the pension reform 2018

    The article is devoted to the study of changes in the number of employed in the economy of the Russian Federation, which should occur as a result of the pension reform in 2018. As the dominant deterministic factor of forecasting the average variant of demographic forecast of the population of the Russian Federation till 2030 is used. The factors of influence are the levels of employment in the context of annual age and gender categories. The growth of the average age of the employed population in Russia and the oscillating "sawtooth" behavior of the labor outflow coefficient during the transition period of the reform from 2019 to 2028 are shown. At the time of the reform, the annual need of the economy for personnel will significantly decrease, which will cause difficulties in finding work for the bulk of job seekers – graduates of the vocational education system, who enter the labor market every year.
