摘要
PURPOSE: An F-function processing device of a seed encoding system and a method thereof are provided to design a masking F-function to remove a process for conversion into an XOR masking value, thereby increasing implementation efficiency.;CONSTITUTION: Arithmetic operation masking converters(B2A,400,402) convert a logically operated masking value which logically operates a seed F-function input value and a random masking value into an arithmetic operation masking value. Masking G-function units(MG,500,502) input the arithmetic operation masking value to output an arithmetic operation.;COPYRIGHT KIPO 2011
