Internet audio/visual secure transmission method having transmitter with pseudo random index table generating encrypted words/separate index set and internet transmitting with receivers table de encrypting.

摘要

The secure transmission method has an information system (10) transmitting to distant receivers (40,42,44,46), over a network link (20). The encrypted words are the same for all transmissions. For each transmission a pseudo random table index (T) is formed and a set of indexes are sent with the digital words to allow de encryption using tables in the receivers.
