Method and apparatus for processing F-function in seed encryption system |
摘要 |
An apparatus for processing an F-function in a SEED encryption system includes: an arithmetic operation masking conversion unit for converting a logical operation mask value obtained by performing a logical operation of a SEED F-function input value and a random mask value into an arithmetic operation mask value; and a masking G-function unit for taking the arithmetic operation mask value from the arithmetic operation masking conversion unit as an input and producing an arithmetic operation output. |
