摘要: A method is described for performing computations in a finite field GF(2N) by embedding it larger ring Rp where the multiplication operation convolution product and squaring rearrangement of bits. Multiplication has complexity N +1, which approximately twice as efficient optimal normal basis (ONB) or Montgomery GF(2N), while same efficiency ONB. Inversion solution quadratic equations can also be performed at least fast previous methods.
