Caller ID parodying produces the valid Caller character, in this manner deciding seem to start from another client. This apparently basic assault strategy has been utilized in the developing communication fake and trick calls, bringing about significant financial trouble. Unfortunately, callerID spoofing is easy to implement but yet it is difficult to have protection against it. In addition, there are not effective and defense solutions available right now. In this research it is suggested the CIVE (Callee Inference & VErification), a compelling and viable guard against Caller ID spoofing. This way it is described how it’s possible to lunch call spoofing and between line describe how CIVE approach method can help to prevent somehow this kind of attacks. Caller ID Spoofing could cause huge financial and political issues special nowadays, when many things even sometimes authentication and verification are available by phone call, like banks approving transactions or two factor authentications and many other things. We believe critical industries specially banks and payment service providers should be protected against such vulnerabilities with their system and make an approach to prevent it, also it is very important to learn people specially who has special social place like politicians or celebrities to know such kind of attack are already exist. For this paper we implemented a call from white house to show there is no limitation and no matter whom you try to spoof, but destination which is the victim receive the call and that make this attack vector dangerous. And even modern communication and even devices like 4G and smart phones are not able to prevent or even detect this kind of attack. This study is a demonstration of the vulnerabilities available. All experiments were conducted on isolated mock-ups.

The article is devoted to increase of efficiency of the means of analysis of biometric characteristics of subjects, interacting with information-control systems of various purpose. It is shown that from the standpoint of the possibility of using as a sensor the reading of the biometric parameters of the standard peripheral equipment of the computer, the widespread use in the information-control systems of voice messages, their high informativeness, the complexity of falsification of biometric information, as well as the possibility of carrying out hidden monitoring, the prospects have analysis tools voice signal. The necessity of improvement of methodology of neural network analysis of voice signal for recognition of emotions and person is grounded. Possibility of increase of efficiency of neural network means of analysis due to adaptation of parameters of neural network model to the conditions of use is determined. The principles of determination of valid neural network models and the most effective type of neural network model used for voice signal analysis have been formed. A coding procedure for the input signal is developed, which allows to use in the neural network a compact representation of the most informative features of a voice signal. A procedure for encoding a neural network output signal has also been developed to increase the efficiency of its learning. The method of neural network analysis of the voice signal is developed, which due to the offered principles of adaptation and procedures of coding of input and output parameters, allows to introduce into neural means a neural network whose architecture is adapted to the expected conditions of use. The effectiveness of the proposed method has been proven experimentally. Experimental studies have shown that the use of the developed method allows to ensure the accuracy of recognition of emotions of the identified speaker, which is approximately 0.94, which corresponds to the best modern decisions in this field. It is suggested to correlate the ways of further research with the development of solutions that would allow to analyze the voice signal of arbitrary duration under the conditions of noise of different kind.

The conceptual basements of constructing an effective encoding method within the bit rate control module of video traffic in the video data processing system at the source level are considered. The essence of using the proposed method in the course of the video stream bit rate controlling disclosed, namely, the principles of constructing the fragment of the frame code representation and approaches for determining the structural units of the individual video frame within which the control is performed. The method focuses on processing the bit representation of the DCT transformants, and at this processing stage transformant was considered as a structural component of the video stream frame at which the encoding is performed. At the same time, to ensure the video traffic bit rate controlling flexibility, decomposition is performed with respect to each of the transformants to the level of the plurality of bit planes. It is argued that the proposed approach is potentially capable to reducing the video stream bit rate in the worst conditions, that is, when component coding is performed. In addition, this principle of video stream fragmen code representation forming allows to control the level of error that can be made in the bit rate control process. However, in conditions where the bit representation of the transformant is encoded, the method is able to provide higher compression rates as a result of the fact that the values of the detection probability of binary series lengths and the values of detected lengths within the bit plane will be greater than in the case of component coding. This is explained by the structural features of the distribution of binary elements within each of the bit planes, which together form the transformer DCT. In particular, high-frequency transformer regions are most often formed by chains of zero elements. The solutions proposed in the development of the encoding method are able to provide sufficient flexibility to control the bit rate of the video stream, as well as the ability to quickly change the bit rate in a wide range of values.

The analysis of the problematic aspects of image processing technologies on aircraft board is carried out. Such technologies relate to the direction of search and preservation of the information component of video information. It is proved that under the conditions of a crisis management system, remote video services are expected to provide a high level of video delivery efficiency and at the same time provide the necessary level of information on the resulting information model. An imbalance is noted: on the one hand, it is possible to provide the necessary level of video information delivery efficiency, but with a low level of information reliability, and on the other hand, having ensured the necessary level of information provision, the reliability of the resulting video model about real events is lost. A prospective direction for solving the problem associated with a decrease in the information intensity of the video stream coming from the aircraft is provided. Particular attention is paid to the factor of preserving information without losing its efficiency and reliability. The rationale for the information sections of video information that contain information redundancy is given. It is proved that this complicates the decryption process. The direction of development of the scientific basis for increasing the efficiency of video information delivery from the aircraft with the preservation of the reliability of information is given. Systematic approach to solving the formulated problematic aspects for video information processing methods consists in developing a technology for their processing aimed at finding and highlighting important objects in the information model is proved It is proved that a promising way to reduce the information redundancy of video information received from the aircraft with the preservation of efficiency and reliability is the methods of allocating the most significant areas from all the information received. The promising technological concept of an effective syntactic description of the elements of aerial photograph areas, taking into account informative information is proposed. The results should be used in the design and manufacture of promising on-board digital scanners.

The article is devoted to the optimization of the structures and traffic development for information transmission in secured corporate networks by quantitative factor. Optimization is carried out in the local task of calculating rational amounts of information. To this end, a mathematical formulation of a local problem is formulated. Which is to optimize the resources of the information system by quantitative criteria. The task is solved by calculating rational amounts of information and entering them in the description of information system resources. It is necessary to evaluate the quality of networks that are being designed based on multicriteria optimization. This is due to the increase in volume and the variety of tasks being promoted to secured corporate networks. This optimization should take into account the full range of recent developments in the field of systematic approach, modern scalarisation principles, decomposition and aggregation techniques, graph theory, optimization algorithms, hierarchical synthesis structuring methods with consistent decision making. The task begins with the construction of information structures, which are linked oriented graphs. The vertices of the graphs are macro-level interaction tasks that carry out information exchange between local area network elements and local area networks, while arcs are information influences or messages. The structures for the micro level are accordingly constructed. Macro-level and micro-level interaction tasks are divided into three types: source resources; transit resources; user resources. The optimization of structures by quantitative factor is carried out in the local task of calculating rational amounts of information. The amount of information means the number of elementary characters. It should be noted that these are volumes of information that consist of basic rather than synthetic indicators. A reasonable amount of information must comply with the completeness of the information which are put forward by consumers task. If the amount of information is less than required, then the network element, the consumer, or the entire network will experience a lack of information. If the required volume is exceeded, there is an unproductive cost of generating, processing and transmitting information or the results of the tasks, as well as threats to the availability of the system. In the global case, the problem is much more complicated because part of the information flow can be an information destructive influence or a threat of breach of information security criteria.

The article is devoted to software bitsliced implementation of the Kalyna cipher using vector instructions SSE, AVX, AVX-512 for x86-64 processors. The advantages and disadvantages of different approaches to efficient and secure block cipher software implementation are shown. It is noted that bitslicing technology combines high speed and resistance to time and cache attacks, but its application to the Kalyna cipher is not available at the moment. The basic approaches to data representation and bitsliced encryption operations are considered, special attention is paid to the effective implementation of SubBytes operation, which largely determines the final performance. Existing methods for minimizing logical functions have been shown to either fail to produce the result in bitsliced format in the case of 8-bit non-algebraic SBoxs, or far from optimal. A heuristic algorithm for minimizing logic functions describing Kalyna SBoxes using the operations of AND, OR, XOR, NOT available in the instruction set of low- and high-end processors is proposed. The results show that a bitsliced description of one SBox requires about 520 gates, which is significantly less than other methods. Possible ways to increase performance by regrouping data into bitsliced variables before and after the SubBytes operation are indicated, which results in more efficient use of vector registers. The bitsliced implementations of Kalyna cipher were measured using C++ compilers from Microsoft and GCC for the Intel Xeon Skylake-SP processor. The results of the bitsliced Kalyna implementation can also be transferred to processors that do not support SIMD instructions, including low-end, to increase resistance to attacks through third-party channels. They also enable switching to ASIC or FPGA-based bitsliced implementation of Kalyna
