Karazin popup.description2 According to the technical task of the purpose was to develop of mathematical and of computer models of information processes in of complex natural and technical systems, the development of computational methods and methods of computer experiment for the analysis of such models aimed at the verification of models and study of properties information processes in modeling systems. In this paper study was conducted and simulation advanced of information and telecommunication technologies like technology LongTermEvolution (LTE), based on three core technologies: OFDM (Orthogonal Frequency-Division Multiplexing), MIMO (Multiple Input Multiple Output) and evolutionary system architecture network (System Architecture Evolution). It examines the main factors of authentication and conducted their analysis. Was noted and substantiated that for every of the factors to authenticate is necessary to determine the full list of attacks from the side the attacking or potential cryptanalyst (perpetrators) to formulate criteria and indicators that would allow them to compare and select those attacks that can are implemented and would ensure the achievement of maximum values of probabilities unauthorized access, and then formulate proposals and recommendations, including for use in mechanisms multi-factor authentication. Performed an experimental studies of reliability such factor as the password. The work package by using the application programming MathCad15 programming model was implemented to generate passwords. The analysis of algorithm of the regime of selective XOR with message authentication code according to NIST SP 800-38D. It is shown that holding of experimental researches full version of this mode for evaluation probability of occurrence conflicts with formation to authenticate codes messages is impossible because of the of large dimension of processed data blocks. Is proposed solution to this problem by developing a reduced model selective XOR with message authentication code. Investigation have shown that the developed reduced model regime of GCM & GMAC allows you to create message authentication code specified length. Object of study - mathematical and computer models of information processes in complex natural and technical systems. Research method - theoretical basics based on the principles and methods of system analysis, mathematical and computer simulation. In this paper developed a method for the synthesis of architectural-oriented time-of parameterized models of parallel algorithms, based in planning the start of execution (time parameterization) its operators through the application of a rational set of methods of parallel processing, determines the composition of the operators, and taking into account the characteristics of the functional modules of the selected element base, and same to the timing requirements characteristics of the algorithm (implementation time, the recovery period of initial data). The presented research complex systems event processing. This study was based on well-known examples of software solutions for such systems and their generalization. The results are based on the study of complex event processing systems. Generalized invariants for such examples led to the formulation of a mathematical model, which was named SIR machine. This model was described in two ways: structural and behavioral. For describing behavioral part of the model, this section was introduce many formal concepts. Have been studied the basic properties of SIR-machines based on these formal concepts.
