Abstract
1. Об'єкт винаходу: Спосіб криптографічного перетворення даних для систем обробки інформації в ЕОМ. 2. Галузь застосування: обчислювальна техніка, а саме до шифрувальних пристроїв і способів з використанням декількох ключів і/або алгоритму. 3. Суть винаходу: на другому етапі псевдо випадкову послідовність, попередньо перетворену в режимі заміни інформації, підсумовують по модулю 2 з послідовністю з необхідним періодом (2257-1), одержуючи на виході попередньо зашифровану інформацію, при цьому Гш на виході рекурентного регістра формують у відповідності із введеним у нього ключем. 5. Технічний результат: підвищення періоду повторення даних на виході, безпечного часу і зменшення імовірності перекриття ключів у просторі і часі, що забезпечує в цілому підвищення реальної криптостійкості.1. Object of the invention: A method of cryptographic data conversion for information processing systems in a computer. 2. Field of application: computer technology, namely to encryption devices and methods using multiple keys and / or algorithm. 3. The essence of the invention: in the second stage, the pseudo-random sequence, pre-converted in the mode of replacing information, is summed in module 2 with the sequence with the desired period (2257-1), receiving the output pre-encrypted information, while GS at the output of the recurrent register is formed in correspondence with the key entered in it. 5. EFFECT: increasing the period of data repetition at the output, secure time and reducing the probability of key overlap in space and time, which provides an overall increase in real cryptocurrency.
