О Методах Оценки Стойкости К Атаке Усеченных Дифференциалов

The existing methods of performing the estimation of the byteoriented ciphers resistance to truncated differentials attack are considered. The approach allowing to estimate resistance of the feistel ciphers with rijndael-like round transformation and the large size of the block (more then 128 bits) to attack of truncated differentials is proved.
