  • Abstract
    Conventional techniques for division in the polynomial factor ring F[z]/(m) or the integer ring Zn use a combination of inversion and multiplication. A new algorithm is presented that computes the division directly and therefore eliminates the multiplication step. The algorithm requires 2 degree(m) (resp. 2 log2 n) steps, each of which uses only shift and multiply-subtract operations.
