TLDR
In this paper, the authors proposed a scheme to charge a user executing cipher communication to obtain a proper cipher system in accordance with ciphering processing speeds and information for ciphering cipher intensity and charge corresponding to the selected cipher system.Abstract:
PURPOSE: To suitably charge a user executing cipher communication. CONSTITUTION: Each of an information presenting side communication terminal 10 and a user side communication terminal 10 is provided with plural ciphering devices 11 having respectively different cipher systems and a selection means 14 for selecting one of the devices 11. A key corresponding to the selected cipher system is generated by a key generating/selecting means 13. An amount corresponding to a cipher system selected by a charging means included in an information presenting center is charged to the user. Thus a proper cipher system is selected in accordance with ciphering processing speeds included in plural cipher systems or the sort of information for ciphering cipher intensity and charge corresponding to the selected cipher system can be properly executed.
