An algorithm which computes the Fourier transform of a sequence of length n over GF(2<sup>m</sup>) using approximately 2nm multiplications and n<sup>2</sup>+ nm additions is developed. The number of multiplications is thus considerably smaller than the n<sup>2</sup>multiplications required for a direct evaluation, though the number of additions is slightly larger. Unlike the fast Fourier transform
