Abstract

PURPOSE:To secure a high-degree privacy protection for the information by carrying out the code conversion while altering the programs sequentially. CONSTITUTION:The information sent from station A is encoded at code converting device PA based on the encoding program sent from code converting device PB of station B, transmitted via transmission line l1, and then decoded at device PB via the decoding program corresponding to the encoding program to be supplied to station B as the information. In this case, the encoding program is changed as the time elapses.
