摘要
PURPOSE: A device and a method for converting the elements expressed in a power form on a Galois field into a polynomial form are provided to minimize the increase of a hardware space when the elements expressed in the power form on the Galois field are converted into the polynomial form. CONSTITUTION: A storage(301) stores the data expressed in the polynomial form. An operator(302) develops an equation by using a Galois field element of the power form as input, extracts variables from the developed equation, and transmits the variables. A selector(303) selects/outputs the data stored in the storage by responding to the input from the operator. A Galois field multiplier(304) operates/outputs the data from the selector.
