Для увеличения производительности при сохранении безопасности хеширования в алгоритме использованы хаотические отображения. Проведено тестирование исходного и модифицированного алгоритмов на устойчивость к коллизиям, которое показало малую вероятность коллизий. Сделан статистический анализ выходных последовательностей, а также производительности алгоритмов. Проведено тестирование алгоритма с помощью набора статистических тестов SP 800-22, которое показало, что двоичная последовательность, генерируемая предложенным алгоритмом, близка к случайной. Протестирована также производительность алгоритма: скорость хеширования модифицированного алгоритма увеличилась на 60 % по сравнению со скоростью хеширования обычного SHA-3.</p></abstract><trans-abstract xml:lang="en"><p>New hashing technique based on SHA-3 (Secure Hash Algorithm-3) is introduced. Chaotic maps are used in this technique to enhance performance without losing security. Introduced algorithm was tested for        resistance against collisions, statistical analysis of output sequences was performed, hashing performance was evaluated. The testing showed a low collision probability. The testing corresponds the standards of National Institute of Standards and Technology and showed that output sequences are close to random. Performance testing showed 60 % enhancement in comparison with plain SHA-3.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хеширование</kwd><kwd>шифрование</kwd><kwd>динамический хаос</kwd><kwd>лавинный эффект</kwd><kwd>статистический криптоанализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hashing</kwd><kwd>encryption</kwd><kwd>chaos</kwd><kwd>avalanche effect</kwd><kwd>statistical cryptanalisys</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bayindir L.
