ABSTRACT:
To allow flexible security level switching according communication situations, a password holding section holds a plurality of device authentication passwords, for example, a temporary password and a private password. The temporary password is valid only under a certain situation and the private password has a high level of confidentiality to increase the device security. A password management section allows the user to add a new password to the password holding section and delete an existing password therefrom. A password selecting section selects the most suitable password for current connection from among passwords in the password holding section according to a user event, information acquired by an external factor acquisition section, and information from a time control section. The selected password is output to a password checking section.
