摘要
We propose a parallel pth powering method over an arbitrary finite field GF(p(m)). Using the proposed method, we present the explicit formulae for the computation of cubing over a ternary field GF(3(m)) which is defined by irreducible trinomials. We show that the field cubing computation for irreducible trinomials, which plays an important role in calculating pairing, can be implemented very efficiently.
