<P>PROBLEM TO BE SOLVED: To solve a problem that since a terminal makes authentication information required for receiving information/content distribution flow to a network since authentication between a server and the terminal is performed via the network, there is a case that the authentication information is eavesdropped by an unauthorized third party on the network in the information/content distribution via the network and the problem becomes further remarkable in the case of the information/content distribution to a radio communication terminal connected to the network via radio communication. <P>SOLUTION: Closed authentication processing is executed between the communication terminal and a storage medium connected to the communication terminal for the communication terminal to receive the information/content distribution from the server. The communication terminal receives the information/content distribution from the server according to a result of authentication processing. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
