A method of computing the product D of two finite field elements B and C modulo an irreducible polynomial f1(x), wherein the finite field elements B and C are represented in terms of an optimal normal basis (ONB) of Type 1 over a field F2" and the irreducible polynomial f1(x) being of degree n, which comprises the steps of representing the element B as a vector of binary digits bi, where bi is a co-efficient of an i th basis element of the ONB representation of element B, in polynomial order representing the element C as a, vector of binary digits ci where ci is a co-efficient of an i th basis element of the ONB representation of element C, arranged in polynomial order initializing a …

Why it's free to use
- Filed December 29, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 29, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
