Open the CIPO recordAbstract From the Canadian patent
An encryption key generator (100) is disclosed which is highly resistant to cryptographic analysis or brute force attacks and which accommodates the , destruction of an encryption key after each use by providing for the recreation of the key without need of key directories or other encryption key storage processes. A constant value (51) and a secret E-Key Seed (50) are applied as an input to a bit-shuffling algorithm (52) to provide a first manyto-few bit mapping and produce a first pseudo-random number. The first pseudorandom number in turn is applied as an input to a secure one-way hash algorithm (53) to provide a second many-to-few bit mapping and produce a second pseudo-random …

Why it's free to use
- Filed March 9, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 9, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 9, 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.
