<p>PROBLEM TO BE SOLVED: To resolve the problem that cost on the receiving side is increased and long time interval is taken for development since is required hardware is required exclusively for descrambling, because a high-speed processing is required due to large processing quantity for rearranging actual data of a packet on the transmitting side in the conventional scrambling methods. SOLUTION: As the scrambling method on the transmitter side, data attribute information in a data packet is converted, re-stored in the data packet, in formation about conversion algorithm used for the above conversion is enciphered and added to the data packet. As the descrambling method on the receiver side, conversion algorithm information added to the data packet is decoded, inverse conversion algorithm is generated, and the algorithm converted in this way is restored.</p> |
