Abstract
A system and method are described for providing biometric authentication to mobile nodes, such as mobile nodes seeking a mobile Internet protocol (mobile IP) connection to a network. The mobile node sends a registration request that includes biometric data. If the biometric data is authenticated, the mobile node is provided with a network address, such as an IP address, to use in network communications.
Claims18
A method of authenticating a mobile node, comprising:
- receiving at a mobility agent a first registration request message associated with a mobile node, wherein the registration message includes biometric data;
- sending a second registration request from the mobility agent to a home agent, the second registration request including the biometric data;
- after receiving the second registration request at the home agent, determining whether the biometric data is associated with an authorized user;
- only after determining that the biometric data is associated with an authorized user, assigning a network address to the mobile node;
- and
- sending the network address to the mobile node in a registration reply message.
A method of authenticating a mobile node, comprising:
- sending an agent advertisement from an agent node, wherein the agent advertisement includes a request for biometric data;
- receiving, at the agent node, a registration request associated with the mobile node, wherein the registration request includes biometric data;
- sending, to an authenticator node, an access request including the biometric data;
- receiving, from the authenticator node, an access acceptance including a network address;
- and
- sending, to the mobile node, a registration reply assigning the network address to the mobile node.
A method of authenticating a mobile node, comprising:
- sending an agent advertisement from a mobility agent, wherein the agent advertisement includes a request for biometric data;
- receiving a first registration message associated with a mobile node, wherein the first registration message includes biometric data;
- sending a second registration request from the mobility agent to a home agent, the second registration message including the biometric data;
- after receiving the second registration request at the home agent, determining whether the biometric data is associated with an authorized user;
- in response to a determination that the biometric data is associated with an authorized user, assigning a network address to the mobile node;
- after assigning the network address to the mobile node, receiving at the home agent network data sent to the assigned network address;
- and
- forwarding the network data from the home agent to the mobile node.
A method of authenticating the user of a mobile telephone comprising:
- receiving, at the mobile telephone, an agent advertisement from an agent node, wherein the agent advertisement includes a request for biometric data;
- collecting biometric data of a user in response to receiving the agent advertisement;
- sending the collected biometric data to the agent node in a registration request message;
- after sending the collected biometric data, receiving a registration reply message including a home address assigned to the mobile telephone;
- and
- receiving, from the agent node, data addressed to the home address.
