“…One of the promising areas, according to the USA NIST experts, is the use of McEliece and Niederreiter crypto-code structures. Practical algorithms for providing basic security services: confidentiality, integrity and authenticity are proposed in [57][58][59]. This approach, taking into account their commercial implementation, does not contain cryptocurrencies and provides not only the required level of cryptographic security, but also the reliability and efficiency of the transmitted data.…”

“…The methodology is based on a comprehensive approach to assessing the effectiveness of the DL system based on the contributions of subsystems of regulatory, organizational, scientific-methodological, information and telecommunications, mathematical and software, logistics, personnel, financial and economic support. It is based on the methods of probability theory [7] and analysis of hierarchies [9] to describe the impact of the importance of contributions of subsystems of the DL system.…”

The current pace of development of information technology has created the preconditions for the emergence of a wide range of tools for providing educational services using distance learning technologies. This is confirmed by the intensification of the use of distance learning systems in the conditions of sanitary and epidemiological restrictions and the need for acute cost savings. The existing scientific and methodological apparatus for studying the quality of functioning of distance learning systems is mostly based on approaches to separate assessment of the effectiveness of their elements and the relevant quality indicators. This limits the ability to take into account important factors in the decision-making process and requires comprehensive consideration of the contributions of relevant subsystems to the functioning of the distance learning system. In order to solve this problem, the article presents a comprehensive methodology for assessing the effectiveness of distance learning system, based on methods of probability theory and hierarchy analysis and describes the patterns of influence on the effectiveness of distance learning system of importance and contributions of its subsystems. Comparative analysis of the data obtained by monitoring and forecasting performance indicators based on the proposed method, shows an increase in the reliability of the assessment within 15-18%, which in contrast to the existing reduction of standard deviation of performance indicators by an average of 26% and ensures the adequacy of the results within certain assumptions and hypotheses. In such conditions, the choice of an appropriate option for the construction of the DN system is ensured by the reliability of the forecast of the results of its operation in the range of 82-85%, which is high enough to make appropriate decisions. The value of this study lies in the possibility of using the tested scientific and methodological apparatus in forecasting the outcome of the system and saving material, financial and human resources in the process of implementing the relevant recommendations in practice. This fact makes it possible to eliminate limitations in the practice of building distance learning systems and creates a new opportunity to cover a wider range of factors that affect the quality of operation.The application of this technique makes it possible to predict the results of the joint operation of the relevant subsystems of the distance learning system, taking into account their contribution to the overall result.

“…In the Russian-language literature to denote [1][2][3][4][5] these concepts use "bookmarks", "loopholes" and "back door" and even "secret passages". Methods of embedding bookmarks in cryptographic algorithms can be divided into three main groups: weak bookmarks, transmission of information through hidden channels, the SETUP mechanism [6][7]. Weak bookmarks are a deliberate weakening of the algorithm, which allows you to know the secret information of the user based on open information [8][9].…”

The entry of mankind into the era of high technology, the rapid growth of computing technology contributes to the expansion of the range of electronic services. To ensure the security of sensitive information, personal data is used cryptographic systems of traditional cryptography (symmetrical cryptosystems) and cryptography with open keys (asymmetric cryptosystems). As a rule, the first provide security services, the second -the distribution of keys. However, in the conditions of totalitarian surveillance in society by the special services of developed countries in cryptographic algorithms "embedded" cryptographic bookmarks, which on the one hand provide "fast" access of special services to confidential information, on the other hand, allow attackers to hack into the cryptosystem and get user data. The article proposes a modification of the wellknown algorithm (OFM) S-box, which provides "elimination" of possible cryptographic bookmarks and increasing crypto resistance in the post-quantum period (the appearance of a full-scale quantum computer, that allows you to hack on the basis of The Grover and Shore algorithms modern symmetrical and asymmetrical cryptosystems). In addition, commercial implementation will ensure the "opposition" of possible crypto-deposits by the special services, that will reduce the risk of hacking by identifying "weak" (vulnerable) places based on cryptographic bookmarks.
