PROBLEM TO BE SOLVED: To safely and accurately distribute authentication information to a user or a user terminal.;SOLUTION: This communication processing method includes a process for requesting authentication using predetermined authentication information through a network to an access destination; a process for acquiring the authentication information which is valid at present from an authentication information management part through a network by transmitting data showing self-validity when authentication failure is reported from the access destination; and a process for requesting the authentication using the acquired authentication information which is valid at present to the access destination. Assuming that the authentication fails, the authentication information management part is made to present data for showing self-validity, and to, for example, encrypt and distribute the authentication information which is valid at present so that it is possible to safely and easily distribute updated authentication information.;COPYRIGHT: (C)2008,JPO&INPIT
