Mobile IP communication scheme incorporating individual user authentication
First Claim
1. A mobile computer management device located in a home network of a mobile computer for enabling the mobile computer to carry out communications while moving over inter-connected networks, the mobile computer management device comprising:
- a registration unit for registering an information on a current location of the mobile computer, based on a registration message transmitted from the mobile computer, which is currently located outside the home network;
a transfer unit for transferring packets destined to the mobile computer to the current location of the mobile computer according to the information registered by the registration unit; and
a user authentication unit for carrying out a user authentication, prior to a registration of the information on the current location of the mobile computer, to judge a properness of a user of the mobile computer according to a user-input-based information contained in a response message returned from the mobile computer in response to a challenge message transmitted from the mobile computer management device to the mobile computer, and controlling the registration of the information by the registration unit according to a result of the user authentication.

Abstract
A mobile IP communication scheme capable of authenticating an individual user who is operating the mobile computer when the mobile computer is connected to a visited site network and transmits a current location registration message to the home agent is disclosed. A user authentication to judge a properness of a user of the mobile computer is carried out according to a user input based information, and the current location of the mobile computer is registered at the mobile computer management device (home agent) when the user is judged as a proper user. The user authentication can be carried out either at the mobile computer management device according to a user input based information received from the mobile computer, or at the mobile computer according to an information entered by the user at the mobile computer.
