  Suppression of a Net-Centric Control System with Radio Cyber Attacks
• Abstract
  • Relevance. Currently control systems architectures tend to the transition from hierarchical to net-centric principle of structure. A net-centric control system is a distributed system, which base elements are integrated into one information space. Such union makes contemporary destabilizing methods ineffective against net-centric control systems as they suppress and jam only individual components of the system. It is important to create new methods of net-centric control systems suppression. The purpose of this paper is to formulate a concept of new telecommunication systems suppression methods. Telecommunication systems are viewed as basic elements of the united information space in the net-centric control system. This paper also describes specific applications for new suppression methods based on existing technical equipment of electronic warfare. Results. New methods of radio cyber-attacks are presented as the evolution of contemporary jamming methods and are described in the paper. The proposed cyber-attacks suppress net-centric system functions by disrupting the multiple access protocols, routing protocols and QoS protocols of telecommunication systems. Unlike existing methods of radio suppression, which specialize only in disrupting individual network elements (links and network nodes), new methods focus on breaching primary functional telecommunication protocols. Applicability. Methods of radio cyber-attacks that are proposed in this paper can be applied to effectively disrupt the net-centric control systems. They also can be used in stability and firmness tests of net-centric control system elements.

  Interval Mathematics and Constructing of Calibration Characteristics of Measuring Tools
• Abstract
  • Relevance. When designing various measuring instruments, the problem arises of constructing the so-called calibration characteristic of a measuring device, i.e. the quantitative dependence of the measurement result on the measured value. This characteristic is inverse to the direct characteristic – the dependence of the measured value on the measurement result. This problem is solved on the basis of approximate data obtained during the experiment with the measuring instrument. A new method for solving this problem is proposed, based on the apparatus of interval mathematics. Goal. The aim of the work is to develop a completely formalized method for constructing the calibration characteristic of a measuring instrument from approximate data obtained in the experiment with this instrument. Method. The method proposed in the article consists in presenting the function of direct conversion of a measuring device in the form of a linear interval function, determining its interval parameters (coefficients) from the experimental data and solving the resulting interval dependence between the measurement result and the measured quantity with respect to the measured value. The method of solving interval equations is used. Result. General formulas are obtained that determine the interval calibration characteristic of the measuring instrument on the basis of the data obtained in the experiment with the instrument. A detailed mathematical analysis of these formulas is performed. General laws are established that obey the direct and inverse (calibration) characteristics of any measuring instrument, as well as the relationship between direct and inverse characteristics. Conclusions. The article proposes a new approach to the construction of calibration characteristics of measuring instruments, based on the use of interval mathematics, for processing data from experiments with instruments. This approach, unlike existing ones, makes it possible to build calibration characteristics of measuring devices and analyze them purely analytically.

  Definition of the Term “Computer Security”
• Abstract
  • The relevance of the task: the use of the term “computer security” began in Russia 20 years ago in textbooks, in educational standards, in scientific publications, in the media. However, term “computer security” has not yet received a generally accepted dictionary or normative definition. In the author's opinion, this situation needs development – the term “computer security” should acquire its logical normative definition in the interests of further development of the theory and practice of the subject area related to ensuring the safe processing of information in computer systems. The purpose of the work is to develop a definition of the term “computer security”, which can be proposed for the role of regulatory and which should set a common basic paradigm for solving a variety of theoretical and practical tasks of providing and evaluating computer security. Method for solving the problem: first, the content of computer security is analyzed, systematized and generalized according to its representations in publications of specialists and in regulatory documents; then a number of principles are adopted that limit the subject area of computer security; in the end, the definition of the term “computer security” is drawn up according to the general logical rules of definition of concepts. This scheme also includes the imperative attribution of computer security to a variety of computerized products, the design and operation of which includes information technologies. The novelty of the solution lies in the new definition of the term “computer security”, which differs from the known approaches to understanding and determining computer security in that it affirms the systemic unity of its three essential aspects: the security of computer data (information), the software security, the security of prescribed functions of computerized products. The theoretical significance of the work is that the new definition of the term “computer security” proposed in it entails the need to develop new standards and methodologies in the future to solve a variety of tasks to ensure and evaluate computer security.

  • Relevance. Rapid development and minimizing of radioelectronic equipment causes increasing density of its mounted and assembled components. At the same time, the continuous useful signal frequency growth respectively leads to increasing frequencies of interference signals. These factors show the significance of the opportunity to detect and localize the signal extremum in multiconductor transmission lines (MCTL) to provide electromagnetic compatibility (EMC), because its results may be useful for locating of sections of transmission lines with parasitic interference and radiation, which can be operatively eliminated. The objective of this work is to formulate methods and algorithms of signal extremum detection and locating in MCTL during designing phase. Methods. This work uses theoretical bases of quasi-static calculation of a response, which takes place at any conductor of MCTL. Results.
