Title:
METHOD FOR MAKING ACCESS TO MOBILE IP NETWORK SAFE
Document Type and Number:
Japanese Patent JP3831331
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To safely perform access to a network.
SOLUTION: Mobility agents offer connectivity to a mobile node via Advertisement messages in a form that can be authenticated by the mobile node. Each advertisement message is signed by the advertising mobility agent and accompanied by a certificate that contains a public key of the advertising mobility agent and is signed by a private key of the administrative server of the advertising mobility agent. Thus, if the mobile node has the public key of the administrative server, the mobile node can authenticate the Advertisement message. When the mobile node does not have the public key of the administrative server, the mobile node requests the public key when it registers with the mobility agent. The public key of the administrative server is sent in a certificate signed by the private key of the administrative server ultimately responsible for authentication of the mobile node.
