“…Along with mutual authentication, encryption and integrity keys are generated [12]. At the same time, the principle of cryptography (Kirchhoff's principle) is fulfilled in limiting the duration of using a permanent key to a minimum and using temporary keys [13]. The authentication procedure starts after the user is identified in the serving network by the procedure for ensuring the privacy of the location of the mobile station [16].…”

The analysis of mobile communication standards is carried out, the functional structure and interfaces of interaction between the structural elements of the cellular network are considered. To understand the principle of communication according to the GSM standard, a block diagram of a mobile switching center (MSC), base station equipment (BSS), control and service center (MCC), mobile stations (MS) is presented. The main algorithms for ensuring the confidentiality and security of mobile subscribers' data, in different types of standards, as well as the vulnerabilities of information flows are considered. In particular, the following dangerous types of attacks have been identified, to which mobile network subscribers are sensitive: sniffing; leakage of personal data; leakage of geolocation data; spoofing; remote capture of SIM-card, execution of arbitrary code (RCE); denial of service (DoS). It is established that the necessary function of the mobile network is the identification of subscribers, which is performed by IMSI, which is recorded in the SIM card of the subscriber and the HLR of the operator. To protect against spoofing, the network authenticates the subscriber before starting its service. In the case of subscriber identification, the subscriber and the network operator are protected from the effects of fraudulent access. In addition, the user must be protected from eavesdropping. This is achieved by encrypting the data transmitted over the radio interface. Thus, user authentication in UMTS, as well as in the GSM network, is carried out using encryption with a common key using the "hack-response" protocol (the authenticating party sends a random number to the authenticated party, which encrypts it according to a certain algorithm using a common key and returns the result back).

“…where Θ denotes the zero matrix, and the expression inside denotes that the relevant matrix is positive definite. Since, in view of the vector and matrix norms defined by (5) and 7, we have X(t) = x(t) , thus the total derivative of the Lyapunov function can be estimated as…”

“…As a method of investigation such systems, the second Lyapunov method with quadratic Lyapunov functions is used [2]. The second Lyapunov method using the Lyapunov function of Lurje-Postnikov type was used in [5] to obtain an estimation of a solution to a control equation with nonlinearity of a sector form.…”
