    Rationale for improving authentication protocols in the conditions of postquantum cryptography
    (Національний авіаційний університет, 2024) Havrylova, Alla; Aksonova, Iryna; Khokhlachova, Yuliia; Milevska, Tetiana; Dunaiev, Sergii
    The paper studies the relevance of the issues of encrypting confidential data for their transmission over unsecured channels of information and communication networks. An analysis of encrypted information exchange on the Internet based on the Google service was carried out in terms of the volume of encrypted web traffic. It is concluded that the difference in traffic volumes between countries is due to the popularity of the types of devices used, the geographic access infrastructure, as well as the availability of software that provides modern types of encryptions. The role of the HTTPS protocol in ensuring the security of working with resources on the Internet is substantiated. The NIST security requirements for modern information and communication systems in the post-quantum period are analyzed. It is determined that within a short period of time the power of computing devices increases exponentially, which entails an increase in the implementation of both already known and new attacks on cryptographic algorithms that ensure the strength of security services in networks. Based on the results of this study, the results of a comparative analysis of the complexity of classical and quantum algorithms were demonstrated. The classification of special attacks was considered according to the signs of influence on computing processes, according to access to systems and means, as well as according to the specifics of the attacks themselves. Solutions submitted for participation in the NIST competition for the definition of security standards through electronic digital signature mechanisms, encryption algorithms and key encapsulation are analyzed. The results of the analysis are presented in the form of a scheme of security and stability of the proposed protocols and algorithms. It is recommended to use TLS protocols to ensure the integrity and authenticity of users when establishing communication sessions with websites. A scheme of the process of authenticated encryption and authentication of an encrypted message transmitted over a TLS connection has been developed. A process scheme has been developed for authentication encryption and decryption of information when establishing a communication session in TLS protocols. A comparative analysis of the characteristics of the TLS 1.3 and TLS 1.2 protocols was carried out.

    Justification of directions for improving authentication protocols in information and communication systems
    (Національний авіаційний університет, 2023) Havrylova, Alla; Khokhlachova, Yuliia; Tkachov, Andrii; Voropay, Natalya; Khvostenko, Vladyslav
    The analysis of information about the conducted cyber-threats makes it possible to identify modern information security problems when transmitted through unprotected communication channels. When conducting such an analysis, various components of the methods of implementing cyber threats are considered, but in this paper, it is proposed to pay attention to the motivational component of the emergence of threats and the existing effective tools for countering them. Such a comprehensive approach will make it possible to predict various modes of cyberattacks that cybercriminals can use against certain systems and to prepare the necessary digital security systems for the implementation of future threats. The influence of the exponential growth of the capacities of computing devices on the growth of the possibilities of implementing attacks by cybercriminals on cryptographic algorithms was also revealed. In this regard, the work considered the possibilities of increasing the level of resistance to such interventions, which are ensured by the NIST requirements for stability and security in the conditions of the post-quantum period. To determine the level of security of data transmission over an insecure network with privacy, integrity and authentication, a comparative analysis of the capabilities of information transmission protocols was conducted. The results of the analysis are presented in the form of a scheme of security and stability of protocols and algorithms that made it to the finals of the NIST competition. To ensure the integrity and authenticity of users when establishing communication sessions with websites, it is recommended to use TLS protocols. A scheme of the process of authenticated encryption and verification ofthe authenticity of an encrypted message transmitted using a TLS connection has been developed. The process diagram of authentication encryption and decryption of information when establishing a communication session in TLS protocols has been developed. A comparative analysis of different versions of TLS protocols was carried out.

    Improved umac algorithm with crypto-code mceliece's scheme
    (Premier Publishing s.r.o., Austria, 2020) Yevseiev, S. P.; Havrylova, Alla
    The article discusses the mathematical model of the mini-version of the UMAC hashing algorithm, using various cryptoalgorithms as a pseudo-random substrate when generating key data, presents the results of studies of the considered mini-versions. A new approach is proposed to ensure the cryptographic stability of this hashing algorithm based on Mac-Elis crypto-code constructions on modified elliptic codes. This approach will provide the required level of cryptographic security in post-quantum cryptography.
