This research proposes an approach to identify and classify tools utilized in information operations that aim to exert suggestive influence. The proposed method combines fuzzy sets theory and fuzzy inference methods with a feature-based analysis approach. By employing this approach, the study focuses on identifying and categorizing tools such propaganda, fake, disinformation, manipulation, and artificial narrative. This framework provides a comprehensive and nuanced understanding of the various tactics employed in information operations, allowing for improved analysis and mitigation strategies.

On 24 February 2022 Russia launched a full-scale invasion of Ukraine. In addition to large-scale military operations against Ukraine, many information attacks were organized. These attacks began before the invasion: for several months, Russia has been actively paving the way for the war by launching different types of information operations in cyberspace. As an example, Russian propaganda media were promoting the idea of “Russian world”, which calls into a question the existence of Ukraine as an independent state and justifies Russian military aggression. In this work, Russian propaganda Telegram channels were analyzed using term frequency analysis with bag-of-words technique. For this analysis, text data from Telegram propaganda channels was collected and processed. The obtained results revealed different patterns in Russian propaganda against Ukraine via Telegram channels.

In recent years, post-quantum (quantum-resistant) cryptography has been actively researched, in particular, due to the National Institute of Standards and Technology's (NIST) Post-Quantum Cryptography Competition (PQC), which has been running since 2017. One of the participants in the first round of the competition is the Mersenne-756839 key encapsulation mechanism based on the AJPS-2 encryption scheme. The arithmetic modulo Mersenne number is used to construct the cryptoprimitives of the AJPS family. In this paper, we propose a forgery attack on the AJPS-2 cryptosystem using an active eavesdropper, and two modifications of the post-quantum AJPS-2 cryptosystem, namely, the modification of AJPS-2 using the arithmetic modulo generalized Mersenne number and Crandall number. Moreover, new algebraic problems are defined, on the complexity of which the security of the created modifications is based. The advantages of these modifications are the extension of the number class used as a module in the cryptosystem and the security against the forgery attack with the active eavesdropper, which was successful in the original AJPS-2.

The purpose of this work is to research AES-128 power analysis template attack and propose a practical way to mitigate such kind of side-channel attacks. The research includes a review of power analysis side-channel attacks, an experiment with the collection of Atmega328PU chip power samples using Hantek 6022BE oscilloscope, processing collected data, and modeling – building a statistical template of the device and analyzing parameters of the side-channel attack.The work is focused on preparation and carrying out the experiment. The experimental bench layout and procedures for collecting and processing the data are considered in detail. The result of this work is the confirmation of the effectiveness of power analysis template attacks on AES-128 for Arduino Uno hardware, and a mechanism for mitigating such kind of attacks on the particular hardware and software implementation. Research materials described in the current work could be used for developing other side-channel template attack mitigation mechanisms for other cryptographic implementations.
