Abstract

Применительно к модулю шифрования/дешифрования существуют способы раскрытия ключа или ключей, используемых этим модулем, путем анализа данных, поступающих в модуль или исходящих из него. Чтобы ослабить эту опасность, предлагаемый способ мультимодульного шифрования предусматривает, что последующий модуль в цепочке модулей шифрования/дешифрования начинает действовать как только ему становится доступной часть результатов, выдаваемых предшествующим модулем цепочки.Международная заявка была опубликована вместе с отчетом о международном поиске.
