HSE Economists Use Search Queries to Forecast Birth Rates
Researchers from the HSE Faculty of Economic Sciences have shown that the accuracy of birth rate forecasts for Russia can be improved by almost 50% by incorporating the dynamics of online search queries related to pregnancy and childbirth into forecasting models. In the best-performing models, the forecasting error fell from 4.6% to 3.2%. The findings have been published in Populations and Economics.

HSE Researchers Discover Who Eats Out in Russia-And Why
Around one-third of Russians (31.3%) rarely eat out or buy ready-made meals. The core group of active consumers—those who eat out or purchase prepared food almost every day or several times a week—accounts for only about 9% of the population. These are the findings of a study conducted by the HSE Institute for Social Policy. According to the researchers eating out is no longer a marker of high social status in Russia.

Differences with high probability and impossible differentials for the KB-256 cipher

Journal of Computer Virology and Hacking Techniques. 2024.
Chukhno A., Дмух А. А., Astrakhantsev R., Курочкин А. В., Астраханцева И. А.

In this paper differences with probability 1 were found for 6 and 7 rounds of KB-256 block cipher. Also using Biham’s et al. shrinking technique we find more than 1700 impossible differentials for the KB-256 cipher with number of rounds from 8 up to 18 (2 rounds more than in the original KB-256)

The difference relations and impossible differentials construction for the KB-256 algorithm
Chukhno A., Курочкин А. В., Фомичев В. М., Прикладная дискретная математика. Приложение 2022 Т. 15 С. 73–77
In this paper, new results of the analysis of the KB 256-3 block cipher algorithm are outlined. We set up a difference relation with probability 1 for the six-round algorithm under study and propose a key recovery method using this difference relation for the nine-round KB 256-3 algorithm. We construct an impossible differential for the ...

Расстояние единственности как определяющее свойство блочного шифра
Chukhno A., Расторгуева М. С., В кн.: Алгебра, теория чисел, дискретная математика и многомасштабное моделирование: современные проблемы, приложения и проблемы истории. Материалы XXII Международной конференции, посвящённой 120-летию со дня рождения академика Андрея Николаевича Колмогорова и 60-летию со дня открытия школы-интерната № 18 при Московском университете.: [б.и.], 2023. С. 164–166.
Зачастую, при оценке  надежности  алгоритмов блочного шифрования, возникают задачи, связанные с исследованием свойств и характеристик множеств подстановок.  Подстановки зачастую являются самостоятельными элементами итерационных преобразований соответствующих механизмов защиты. В этой связи изучение свойств подстановок, максимально усложняющих проведение процедуры дешифрования, приобретают особую практическую и теоретическую значимость.  С другой стороны, сам алгоритм блочного шифрования можно рассматривать как случайную ...

СТАТИСТИЧЕСКОЕ ТЕСТИРОВАНИЕ СОВРЕМЕННЫХ ИТЕРАТИВНЫХ БЛОЧНЫХ ШИФРОВ С ПОМОЩЬЮ ПРОГРАММНОЙ БИБИЛОТЕКИ "УНИБЛОКС-2015"
Perov A., Инновации в жизнь 2016 № 2(17) С. 89–97
The statistical analysis of iterative block ciphers is carried out for detection of dependences of statistical properties of output sequence depending on number of rounds. It is reasonable to utilize source codes available in the Internet, but their integration into own programs is impeded by at least the following reasons. Firstly, different implementations have different ...

О некоторых направлениях научных исследований в области криптоанализа симметричных алгоритмов
Perov A., Вестник НГУЭУ 2016 № 3 С. 290–298
A survey of some important scientic directions in the sphere of symmetric cryptography is presented. We emphasize problems connected with weak keys, with statistical analysis of symmetric algorithms and with investigation of iterative constructions. Some problems, specic to stream ciphers, iterative block ciphers and cryptographic hash-functions, are considered. We also advocate practical significance of scientic ...

О возможности применения сверточных нейронных сетей к построению универсальных атак на итеративные блочные шифры
Perov A., Пестунов А. И., Прикладная дискретная математика 2020 № 3 С. 46–56
The paper explores possibility of applying convolutional neural networks to the security analysis of iterative block ciphers. A new approach for constructing distinguishing attacks based on a convolutional neural network is proposed. The approach is based on distinguishing between graphic equivalents of ciphertexts received by the CTR (counter) encryption mode after different number of rounds, including the number of ...

In this paper we consider a bit-sliced implementation of the non-linear transformation shared by GOST R 34.12-2015 “Kuznyechik” block cipher and GOST R 34.11-2012 “Streebog” hash function. We combine analytical and computer methods to get a 226 Boolean operations representation. ...

In this paper we study rotational probabilities for 2-GOST block cipher, which is a modification of GOST 28147-89. We show that despite the fact that this algorithm does not belong to the family of ARX-transformations in some cases it is possible to evaluate its rotational properties and evaluate the applicability of rotational analysis. ...
