This invention provides for the encoding of synchronization information in the transmitted streamed data so that the receiver and transmitter may synchronize their, internal cipher states. It uses a random number generator at the transmitter subsystem, as well as one-way cryptographic hash functions and streaming cipher , algorithms at, both the transmitter subsystem and the receiver subsystem. The output of the random, number generator at the transmitter is included in the transmitted data packet, and data, in the packet is encrypted using a key derived from this same output value. Since this, derivation is earned out using a number of encryption steps such as a one-way , hash, …

Why it's free to use
- Filed December 29, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 29, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
