Abstract
A Galois field multiplier for GF(2.sup.n), with n=2m, multiplies two n-bit polynomials to produce a(x)*b(x)=a(x)b(x) mod g(x), where g(x) is a generator polynomial for the Galois field and '*' represents multiplication over the Galois field, by treating each polynomial as the sum of two m-bit polynomials:
