Patent ID: 6973086

Claim:
A method for securely communicating packets that include the home address destination option in a mobile IPv6 protocol network, comprising: (a) providing a care of address to a mobile node that employs an access router to communicate with at least one resource over a visited network; (b) enabling a binding update message from the mobile node to be forwarded by the access router to another node for authentication, wherein the other node sends a binding acknowledgement message to the mobile node if a home IP address included in the binding update message is authentic; and (c) if the binding acknowledgement message from the other node is determined by the access router to verify the home IP address for the mobile node, enabling the mobile node to communicate another type of data through the access router with at least one resource over the visited network, wherein until the home IP address is verified by the access router, the mobile node is unable to communicate the other type of data through the access router.
