Recently, cryptographic applications based on finite fields have attracted much interest. This paper presents two new algorithms, called time-dependent and time-independent multiplication algorithms over a finite field GF(2m) by employing an interleaved conventional multiplication and a folded technique. The proposed algorithms permit efficient realization of the bit-parallel multiplication using iterative arrays. The results show that our proposed time-dependent and time-independent multipliers save about 38% and 54% space complexity as compared to the traditional multipliers, respectively.
