Предложена модификация схемы постобработки случайных чисел с использованием многоканального сигнатурного анализатора, коэффициента сжатия во времени и изменяемого количества источников энтропии. Проанализировано влияние основных параметров схемы на энтропию обрабатываемых последовательностей и результаты статистических тестов NIST 800-22. Оценены аппаратные затраты на реализацию на программируемых логических интегральных схемах и выполнено сравнение с аналогами. Полученные результаты подтверждают перспективность схемы для применения в энергоэффективных и требовательных к аппаратным затратам генераторах истинно случайных чисел.</p></abstract><trans-abstract xml:lang="en"><p>An analysis of post-processing circuits based on a linear feedback shift register is carried out. A modification of the random number post-processing circuit using a multi-input signature analyzer is proposed, which employs a time compression factor and a variable number of entropy sources. The influence of the circuit’s key parameters on the entropy of processed sequences and on the results of NIST 800-22 statistical tests is analyzed. The hardware costs of implementing the circuit on programmable logic integrated circuits are estimated, and a comparison with similar circuits is performed. The results confirm the circuit’s potential for use in energyefficient and area-efficient true random number generators.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>случайные данные</kwd><kwd>постобработка случайных чисел</kwd><kwd>многоканальный сигнатурный анализатор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>random data</kwd><kwd>random number post-processing</kwd><kwd>multi-input signature analyzer</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">Chai, H.
