Models and algorithms for highly secure authentication of users of information systems

When solving the problem of organizing user access to information systems (IS), various methods of authentication and identification are used. The article proposes a conceptual and functional model of a highly reliable user authentication system based on the use of biometric parameters. Algorithms for training a neural network converter biometrics-code (BNC), the formation of an identifier and authentication of IS users are considered.

Keywords: authentication, biometrics, access, means of information protection, cryptographic protection.

Theoretical studies of free oscillations of the orbital pendulum

The article is devoted to the theoretical proof of the hypothesis of Prof. Khlystunova M.S. on the stability positions, the study of metrological characteristics, including the calculation of the value of the period of free natural oscillations of the orbital pendulum. The design of such a pendulum is considered, which is a dumbbell with equal masses and freely rotating on an axis in the center of its masses. It is shown that the solution of the differential equation of free oscillations of a pendulum placed on board a spacecraft in near-Earth space orbit or on the Earth's surface confirms the hypothesis that the pendulum has two equilibrium positions with the same frequency of natural oscillations. An important result of this study is the conclusion that the frequency of natural oscillations of the orbital pendulum does not depend on the length of the dumbbell and the magnitude of its masses.

Keywords: orbital Khlystunov pendulum, near-Earth orbit, spacecraft, equilibrium positions, period of free natural oscillations, calculation.
