ABSTRACT:
The computing device calculates an equivalence H0≡2m*k+1(mod n) relating to a divisor n of 2m*k+1(step A), computes an equivalence H≡2E(p, m, k)(mod n) of 2E(p, m, k)(mod n) from H0by an REDC operation (step B), and performs a correction operation by H=REDC (H, G)nfor g=2k*G(p, m, k)when 2p>m×k (step C).
