Open the CIPO recordAbstract From the Canadian patent
The present invention provides a transformation method for obtaining optimized hardware and software implementations of elliptic curve cryptographic systems including elliptic curve encryption, decryption and signature functions. The , method is applicable to any elliptic curve group G defined over any field F. More specifically, the present invention is characterized by speeding up the elliptic curve point multiplication operation which consists of the , calculation Q = eP where P is a member of G and e is an integer. This is achieved by transforming P = (x, y) to a point P' = (x' y') in order to , compute Q' = (u, v = eP'). The point P' is not necessarily on the elliptic curve, but …

Why it's free to use
- Filed December 4, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 4, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 4, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
