First Claim
1. A method for auto-configuring a home address by a mobile node, the method comprising:
- transmitting an update message from a mobile node to a home agent, the update message comprising at least a random number and an option for requesting a home prefix from the home agent;
processing the update message, by the home agent, and transmitting a home prefix message with the home prefix, from the home agent to the mobile node, the home prefix message being protected by a configuration key derived from the random number;
deriving, by the mobile node, a home address from the home prefix and transmitting the home address to the home agent for verification of the uniqueness of the home address; and
sending an acknowledgement message, from the home agent to the mobile, upon successful verification.

Abstract
A method for auto-configuring a home address by a mobile node, the method includes transmitting an update message from a mobile node to a home agent. The update message includes at least a nonce and an option for requesting a home prefix from the home agent. The method further includes processing the update message, by the home agent, and transmitting a home prefix message with the home prefix, from the home agent to the mobile node. The home prefix message is protected by a configuration key derived from the nonce. The method also includes deriving, by the mobile node, a home address from the home prefix and transmitting the home address to the home agent for verification of the uniqueness of the home address and sending an acknowledgement message, from the home agent to the mobile, upon successful verification of the uniqueness of the home address.
