Abstract
Square root extraction over GF(2m) is introduced and a new hardware architecture for exponentiation over GF(2m) based on the square root extraction is proposed. Compared with the classical square-and-multiply architecture, the proposed architecture is shown to calculate exponentiation with fewer cycles over GF(2m) in most cases.
